Health risk and occupation in agricultural settings in Italy 总被引:2,自引:0,他引:2
Miligi L Aprea C Settimi L 《International journal of occupational and environmental health》2005,11(1):96-102
In Italy several studies have examined the association between cancer and occupation in agricultural settings, focusing on exposure to pesticides. Most of the cohort studies evaluated cancer mortality in licensed pesticide users. Many case-control studies considered hematolymphopoietic malignancies, and the most recent studies observed increased risks for use of specific chemical classes of pesticides. Preliminary data on pesticide-related illnesses must be taken into account, and a national surveillance system should be implemented to identify areas at high risk and to promote exposure-control programs. 相似文献

This paper provides an overview of U.S. government pesticide risk management efforts over time and in recent years, relevant to chronic health risks of pesticides. Pesticides are in widespread usage in the U.S. With hundreds of active ingredients and thousands of products on the market, management of pesticide risks has been a daunting challenge. The first legislation providing federal authority for regulating pesticides was enacted in 1910. With the establishment of the U.S. Environmental Protection Agency in 1970 and amendments to the pesticide law in 1972, the federal government was for the first time given the authority to regulate health and environmental risks of pesticides. However, older pesticide risks were not addressed until legislation was enacted in 1988, requiring "reregistration" and 1996, requiring that pesticide food standards are safe for children. In result, the U.S. has seen an expansion of development of pesticide products that are registered as "reduced risk" or are biologicals. Additionally a large number of older pesticides have been cancelled or reduced from the market and/or from individual food uses. Through biomonitoring data, the U.S. may now be seeing trends in reduction of exposure to certain pesticides, the organophosphate insecticides. However, pesticide sales data through 2001 do not provide evidence for such trends. 相似文献

Epidemiologic information about asbestos-related diseases in Italy, derived from mortality data, epidemiologic surveillance, and analytical studies, is presented. These systems evidence exposures to asbestos and relative risks for populations exposed in work environments and also in the general environment, and provide objective data to identify sources of exposure and for risk management. Limitations and perspectives of Italian studies are considered, and public health issues evaluated: the risk for migrants, social security aspects, and asbestos-related disease in the courts. Although asbestos use was banned in 1992, information and risk communication efforts should be implemented to empower affected individuals and communities and to pursue equitable allocation of resources for primary prevention and health surveillance. 相似文献

Formative evaluation of south Georgian migrant farm workers' access to information and products to promote pesticide protection and understanding of cancer risk associated with pesticide exposure was conducted using field observation, in-depth interviews of Georgia's Migrant Health Program's outreach workers, and structured face-to-face surveys of migrant farm workers. The data indicated that fewer than one-third of the pesticide products reviewed contained messages about pesticide use and exposure risk for humans. Risk information on products appeared in English only. Few protective devices were available for purchase. Migrant farm workers were aware in a very general sense of health risks posed by pesticides, but they were specifically unaware of the reach of pesticides sprayed, as illustrated by their field behaviors. Findings also demonstrated the need to educate outreach workers about migrant farm workers' cancer risk, so that they may act as migrant farm workers' health advocates to reduce the adverse effects associated with pesticide exposure. 相似文献

It has been suggested that high exposure to pesticides, including poisoning, experienced by agriculture workers and rural residents may result in an elevated risk of psychiatric disorders and suicidal behavior. Epidemiological data supporting this hypothesis are very limited. An updated systematic review was conducted in epidemiologic literature on the relationship of pesticide exposure with depression and suicide published over the last 15 years by using MEDLINE database. A total of 11 studies on depression and 14 studies on suicide met inclusion criteria. Depression or other psychiatric disorders have shown increased risks associated with previous pesticide poisoning in 5 studies, with statistically significant odds ratios (OR) ranging from 2.08 to 5.95. Lower risk estimates have been found for chronic pesticide exposure. Among studies on suicide, 4 reports found increased suicide rates in areas with intensive pesticide use (OR between 1.60 and 2.61) compared to areas with lower pesticide use. Occupation in agriculture has shown a significant association with higher suicide risk than other occupational groups in 4 studies (OR between 1.30 and 4.13), but not in one recent report. Regarding specific pesticides, lifetime use of chlorpyrifos was related with increased suicide mortality (OR = 2.37) in one study. Scientific evidence of association between pesticide exposure and either depression or suicide has been shown in some populations, in studies using varying epidemiological approaches, but is still very limited and inconclusive. Review of the literature warrants further research to explore such relationships, in particular prospective studies among large samples of high- and low-dose-exposed workers, using detailed exposure assessments, and evaluating other potential sources of psychological stress. 相似文献

There are hundreds of studies of cancer and agriculture chemicals. However, few have focused on a single pesticide or class of pesticide. While cancer studies of nonspecific pesticide exposure among populations may provide hypotheses for additional testing, they contribute little to the understanding of the health risks of specific agricultural chemicals. This review concentrates on both the cancer findings and the exposure parameters in cohort studies of workers who manufacture or apply pesticides. Occupational studies of pesticide manufacturers and applicators provide important contributions to the causal assessment of the carcinogenicity of specific pesticides because the exposure is often longer, more intense, and better defined than for other study populations. Among the studies reviewed, there is little indication of increased cancer risk among pesticide manufacturers or sprayers. Limitations in sample size, exposure assessment, and the small number of studies make causal inference difficult. Additional methodological improvements with respect to exposure would contribute significantly to the understanding of the potential cancer risk from individual pesticides. 相似文献

A preliminary study undertaken by the CSIR in July 1993
on the health effects of aerial crop spraying of pesticides in the Vaalharts
irrigation area in South Africa indicated that potential health risks could
exist for the inhabitants of this area. An extensive scientific health risk
assessment and epidemiological study to determine the actual health risks, is
very expensive and requires medical and financial justification. The aim of
this study was to develop a theoretical health risk model, which could be
used as a predictive tool to determine as accurately as possible from the
data available if a complete scientific health risk assessment study is
justified. The actual amounts of pesticides sold in the Vaalharts area by two
major pesticide manufacturers were used to perform a theoretical health risk
assessment. The risks were assessed by making use of RISK*ASSISTANT, a
computer modeling system and chemical database. The United States
Environmental Protection Agency's (EPA) health risk model was applied to
the data to identify the hazards, assess the exposures and dose response, and
characterize the risks. Three exposure scenarios, namely, the ingestion of
food and water and the inhalation of air were evaluated. The method used to
calculate the risks varied according to the type of health hazard and the
results were characterized accordingly. The acute health effects due to
exposure to pesticides are well known and the risks are easy to determine.
However, the risks associated with chronic health hazards were more difficult
to calculate. For this reason a ranking model was developed which made use of
a point scoring system. This model highlights those pesticides which have the
greatest possibility of causing chronic health effects. From the results it
can be concluded that very large amounts of pesticides are used in the
Vaalharts area and that the community might be at risk to chronic health
effects. Although the theoretical health risk assessment model was
successfully used in this study, its effectiveness as a predictive tool still
has to be proven by a complete scientific study.

Current practices of applying agricultural chemicals play a major role in the environmental health concerns of agriculture. Those who mix, load, and handle the concentrated formulations run the greatest risk of exposure but field hands and others can encounter significant levels of pesticides. Drift can be a major source of contamination to residents, wildlife, and water sources. Improved methods of application and ways of reducing the total amount of pesticide applied can help reduce environmental contamination. Chemigation, direct injection, closed system handling, and fertilizer impregnation are examples of technology that affect the efficiency of applying agricultural chemicals. An area of beneficial research is related to leak and spill technology. Current surveys indicate that point sources such as spills, mixing and loading areas, back-siphoning, and direct routes for surface water movement into the ground are often a major cause of pesticides reaching groundwater. The commercial dealer/applicator provides storage, handling, mixing, and loading for large amounts of chemicals and has received limited guidance regarding the products. Education remains an important element of any rural environmental health strategy. With appropriate information about pesticide risks and groundwater, people will be better equipped to address environmental concerns. By design, agricultural chemicals are biologically active and, in most cases, toxic. Thus, they pose potential risks to humans, wildlife, water, and the environment in general. The magnitude of the risks depends to some degree on the methods and techniques used to apply the chemicals. Pesticides are applied by persons possessing a variety of skills, using equipment ranging from hand-operated systems to aircraft. 相似文献

Nearly 50% of the world labour force is employed in agriculture. Over the last 50 years, agriculture has deeply changed with a massive utilisation of pesticides and fertilisers to enhance crop protection and production, food quality and food preservation. Pesticides are also increasingly employed for public health purposes and for domestic use. Pesticide are unique chemicals as they are intrinsically toxic for several biological targets, are deliberately spread into the environment, and their toxicity has a limited species selectivity. Pesticide toxicity depends on the compound family and is generally greater for the older compounds; in humans, they are responsible for acute poisonings as well as for long term health effects, including cancer and adverse effects on reproduction. Due to their intrinsic toxicity, in most countries a specific and complex legislation prescribes a thorough risk assessment process for pesticides prior to their entrance to the market (pre-marketing risk assessment). The post-marketing risk assessment takes place during the use of pesticides and aims at assessing the risk for exposed operators. The results of the risk assessment are the base for the health surveillance of exposed workers. Occupational exposure to pesticides in agriculture concerns product distributors, mixers and loaders, applicators, bystanders, and rural workers re-entering the fields shortly after treatment. Assessing and managing the occupational health risks posed by the use of pesticides in agriculture is a complex but essential task for occupational health specialists and toxicologists. In spite of the economic and social importance of agriculture, the health protection of agricultural workforce has been overlooked for too many years, causing an heavy tribute paid in terms of avoidable diseases, human sufferance, and economic losses. Particularly in the developing countries, where agricultural work is one of the predominant job, a sustainable model of development calls for more attention to occupational risks in agriculture. The experience of many countries has shown that prevention of health risk caused by pesticides is technically feasible and economically rewarding for the individuals and the whole community. A proper risk assessment and management of pesticide use is an essential component of this preventative 相似文献

The epidemiology of pesticide exposure and cancer: A review 总被引:4,自引:0,他引:4
Cancer is a multifactorial disease with contributions from genetic, environmental, and lifestyle factors. Pesticide exposure is recognized as an important environmental risk factor associated with cancer development. The epidemiology of pesticide exposure and cancer in humans has been studied globally in various settings. Insecticides, herbicides, and fungicides are associated with hemopoetic cancers, and cancers of the prostate, pancreas, liver, and other body systems. The involvement of pesticides in breast cancer has not yet been determined. In developing countries, sufficient epidemiologic research and evidence is lacking to link pesticide exposure with cancer development. Agricultural and industrial workers are high-risk groups for developing cancer following pesticide exposure. Children of farm workers can be exposed to pesticides through their parents. Maternal exposure to pesticides can pose a health risk to the fetus and the newborn. The organophosphates are most the commonly used compounds, but the organochlorines are still permitted for limited use in developing countries. Pesticide exposure, independently or in synergism with modifiable risk factors, is associated with several types of cancer. 相似文献

Use of point-of-sale data to track usage patterns of residential pesticides: methodology development
Nyree Bekarian Devon Payne-Sturges Stuart Edmondson Bill Chism Tracey J Woodruff 《Environmental health : a global access science source》2006,5(1):15
Background
Residential-use pesticides have been shown to be a major source of pesticide exposure to people in the United States. However, little is understood about the exposures to household pesticides and the resultant health effects. One reason that little is known about home-use pesticide exposure is the lack of comprehensive data on exposures to pesticides in the home. One method to help ascertain the amount of pesticides present in the home is use of point-of-sale data collected from marketing companies that track product sales to obtain the volume of pesticides sold for home-use. This provides a measure of volume of home-use pesticide. 相似文献13.
Determining aggregate and cumulative risks from exposures to pesticides presents a number of challenges. The analysis must capture the correlations in residues that occur from both additive and exclusionary processes in the use of pesticides. The analysis also requires a quantitative mechanism for evaluating risks associated with exposures to mixtures of pesticides. This paper presents an analysis of aggregate exposures and risks associated with exposures to a pesticide, Alpha, and the cumulative exposure to and risk from three pesticides, Alpha, Beta, and Gamma. The cumulative risks are evaluated by determining the systemic (absorbed) doses that result from inhalation, dermal, and oral exposures to the pesticides. A 'relative toxicity' model is used to evaluate cumulative risks. The assessment of cumulative exposure was performed using the LifeLine Version 1.0. The model simulates pesticide exposure using an individual-based approach where daily exposures are evaluated for each person, season, and location. 相似文献

A major goal of studying farmworkers is to better understand how their work environment, including exposure to pesticides, affects their health. Although a number of health conditions have been associated with pesticide exposure, clear linkages have yet to be made between exposure and health effects except in cases of acute pesticide exposure. In this article, we review the most common health end points that have been studied and describe the epidemiologic challenges encountered in studying these health effects of pesticides among farmworkers, including the difficulties in accessing the population and challenges associated with obtaining health end point data. The assessment of neurobehavioral health effects serves as one of the most common and best examples of an approach used to study health outcomes in farmworkers and other populations exposed to pesticides. We review the current limitations in neurobehavioral assessment and strategies to improve these analytical methods. Emerging techniques to improve our assessment of health effects associated with pesticide exposure are reviewed. These techniques, which in most cases have not been applied to farmworker populations, hold promise in our ability to study and understand the relationship between pesticide exposure and a variety of health effects in this population.

Pesticides are widely used in agricultural production to prevent or control pests, diseases, weeds, and other plant pathogens in an effort to reduce or eliminate yield losses and maintain high product quality. Although pesticides are developed through very strict regulation processes to function with reasonable certainty and minimal impact on human health and the environment, serious concerns have been raised about health risks resulting from occupational exposure and from residues in food and drinking water. Occupational exposure to pesticides often occurs in the case of agricultural workers in open fields and greenhouses, workers in the pesticide industry, and exterminators of house pests. Exposure of the general population to pesticides occurs primarily through eating food and drinking water contaminated with pesticide residues, whereas substantial exposure can also occur in or around the home. Regarding the adverse effects on the environment (water, soil and air contamination from leaching, runoff, and spray drift, as well as the detrimental effects on wildlife, fish, plants, and other non-target organisms), many of these effects depend on the toxicity of the pesticide, the measures taken during its application, the dosage applied, the adsorption on soil colloids, the weather conditions prevailing after application, and how long the pesticide persists in the environment. Therefore, the risk assessment of the impact of pesticides either on human health or on the environment is not an easy and particularly accurate process because of differences in the periods and levels of exposure, the types of pesticides used (regarding toxicity and persistence), and the environmental characteristics of the areas where pesticides are usually applied. Also, the number of the criteria used and the method of their implementation to assess the adverse effects of pesticides on human health could affect risk assessment and would possibly affect the characterization of the already approved pesticides and the approval of the new compounds in the near future. Thus, new tools or techniques with greater reliability than those already existing are needed to predict the potential hazards of pesticides and thus contribute to reduction of the adverse effects on human health and the environment. On the other hand, the implementation of alternative cropping systems that are less dependent on pesticides, the development of new pesticides with novel modes of action and improved safety profiles, and the improvement of the already used pesticide formulations towards safer formulations (e.g., microcapsule suspensions) could reduce the adverse effects of farming and particularly the toxic effects of pesticides. In addition, the use of appropriate and well-maintained spraying equipment along with taking all precautions that are required in all stages of pesticide handling could minimize human exposure to pesticides and their potential adverse effects on the environment. 相似文献

This article seeks to characterize the risks related to the use of pesticides in dairy production, in terms of legislation, health and perception of risk for workers involved in this activity. It is based on methodological articulation that included: a) systematic review of the reference literature on the research topic; b) analysis of related legislation (veterinary products and pesticides); c) risk identification regarding the use of veterinary products formulated using active ingredients listed as pesticides; d) and risk perception analysis of a group of dairy production workers. Results indicate a situation of particular interest to Public Health. Regarding dairy production workers, the invisibility of risks associated with handling pesticides for veterinary use, increases their exposure and is related to several health problems, especially for women. This same invisibility leads to a neglect of the prohibition period between pesticide use and consumption of other products. Part of the problem may be associated with the non-classification of pesticides for veterinary use as 'pesticides' (they are classified as veterinary products), which highlights the importance and the urgency of discussion of the theme. 相似文献

The inappropriate use of toxic chemicals is common in developing countries, where it leads to excessive exposure and high risks of unintentional poisoning. The risks are particularly high with the pesticides used in agriculture, where poor rural populations live and work in close proximity to these compounds, which are often stored in and around the home. It is estimated that 99% of all deaths from pesticide poisoning occur in developing countries. Whilst the acute toxicity of pesticides has been well documented, there is still relatively little known of the effects on health of chronic pesticide exposure. Organophosphate insecticides have been extensively used in agriculture in developing countries, with little protection for the communities and individuals thus exposed. Given the indisputable chronic exposure of vulnerable groups to organophosphate compounds, including pregnant women, the fetus and young children, the potential for widespread adverse effects is considerable. Thus, whilst there is some evidence that chronic exposure may have adverse effects on health, there is an urgent need for high-quality observational and interventional studies of both occupational and environmental exposure to these compounds. 相似文献

Pesticide exposure and poisoning among children can lead to devastating long-lasting health effects that impact their human rights, with communities in low- and middle-income countries experiencing the negative impacts of pesticides more profoundly than those in high-income countries. While United Nations agencies recommend banning highly hazardous pesticides responsible for serious pesticide poisonings, childhood pesticide poisoning is rarely discussed, especially from a human rights perspective. In India, a country with a large population of children and widespread pesticide use, no law or policy addresses pesticide poisoning among children. This lack of prioritization leads to gaps in poisoning surveillance and lack of government action to prevent poisoning, causing violations of children’s rights. The proposed pesticides ban can reduce pesticide poisoning among children in India, but to fully protect children’s rights, the government needs to establish comprehensive pesticide poisoning surveillance and ensure the mainstreaming of pesticide poisoning prevention into law and policy based on a human rights framework. 相似文献

Exposure assessment as a component of observational health studies and environmental risk assessment
Ott MG 《Scandinavian journal of work, environment & health》2005,31(Z1):110-4; discussion 63-5
Assessing pesticide and nonpesticide exposures in agricultural settings is a daunting task. This is especially the case when such assessments are undertaken as a component of health studies to evaluate cancer risk. In this review, key exposure assessment issues are outlined and discussed in the context of pesticide-specific health risk assessments and three recent studies of large, geographically defined farmer and farm family populations. The specific topics addressed include the assessment of cumulative exposures to both older and more recently registered pesticides, the role of biomarker studies in exposure assessment, and uses of data on nonroutine high-exposure events. 相似文献

OBJECTIVE: We describe the sociodemographic characteristics and determinants of pesticide exposure in agricultural workers applying pesticides. METHODS: The workers selected were included in a case-control study carried out in the Autonomous Community of Valencia in Spain. Contact was made by telephone and individuals who had been involved in agricultural work during the relevant period of exposure were interviewed face-to-face to gain information on the following determinants of pesticide exposure: crops and periods worked, mixing of products, treatment equipment, participation in the washing of equipment, use of personal protection during the treatments and knowledge of the risks of pesticide exposure. RESULTS: Eighty-nine workers, aged between 16 and 46 years old, were included. Most of the interviewees had primary education or less. Pesticide treatments were mostly applied on high crops (82%), with manual equipment (61%) and throughout the year (45%). Workers frequently performed tasks involving additional exposure to pesticides (mixing chemicals, 66%, or washing equipment, 60%). Sixty-five percent of the workers used no personal protection or used it defectively. No differences were found in personal protection use according to age, family income or education. Most of the workers (90%) reported knowledge of the health risks of pesticide exposure and 21% of them rated the risk as null. CONCLUSIONS: Workers involved in pesticide application use personal protection measures very defectively. There is a clear need to develop specific prevention programs for these workers. The determinants of pesticide exposure in agricultural workers described in this study should be properly assessed in epidemiological studies of the health effects of pesticides on agricultural workers. 相似文献
