The authors aimed to assess genotoxic damage in the lymphocytes of workers chronically exposed to ionizing radiation. The studied population included 15 exposed donors of the radiology unit of a public hospital in La Plata, Argentina. The control group included 15 nonexposed employers from administrative areas that the authors matched by age, sex, and smoking habits. The mean frequency of cytogenetic damage was higher in the exposed group than in the unexposed group for aneuploidy and structural chromosome aberrations. They observed the highest difference when achromatic lesions (or gaps) were considered. The comet assay showed that the frequency of cells with low damage was higher in the exposed group than in the unexposed group. A mean length analysis showed significant differences between exposed and nonexposed people. The results can be considered to be consistent evidence of occupational radiation exposure, and the results indicate that the workers must be advised to avoid or minimize their exposure.  相似文献

Although other aromatic compounds (e.g., benzene, toluene, polycyclic aromatic hydrocarbons (PAH), etc.) have been thoroughly studied over the years, styrene has been given little attention probably due to its lower rate of industrial use. In addition, it is less toxic than benzene and PAH, proven carcinogens. However, it is classified as a mutagen and thus potentially carcinogenic. Its main use is in the production of the polymer polystyrene and in the production of plastics, rubber, resins, and insulators. Entry into the environment is mainly through industrial and municipal discharges. In this review, the toxicological effects of styrene on humans, animals, and plants are discussed. Its mode of entry and methods of monitoring its presence are examined. Although its effects on humans and aquatic life have been studied, the data on short- or long-term exposures to plants, birds, and land animals are insufficient to be conclusive. Since exposure to workers can result in memory loss, difficulties in concentration and learning, brain and liver damage, and cancer, development of accurate methods to monitor its exposure is essential. In addition, the review outlines the present state of styrene in the environment and suggests ways to deal with its presence. It might appear that the quantities are not sufficient to harm humans, but more data are necessary to evaluate its effect, especially on workers who are regularly exposed to it.  相似文献

Assessment of ecological risks during manufacturing, use, transport, and disposal are becoming increasingly important as planning tools during development of new products. The objective of this study was to establish the potential ecotoxicological hazard associated with two polycarboxylate polymers in water, sludge, sediment, and soil. The concentrations of both polymers were quantified using 14C-radiolabeled synthesis and liquid scintillation counting (LSC). The program included water column acute and chronic exposures with Ceriodaphnia dubia, Pimephales promelas, and Selenastrum capricornutum, sediment exposures with Chironomus riparius, and soil exposures with Eisenia foetida. Sludge treated with either polymer, from a semicontinuous activated sludge unit, was used to evaluate the effect on growth of five plants. The hazard assessment program for both polymers indicated a very low order of toxicity as defined by the U.S. EPA and OECD. Very small fractions of each polymer may not be removed by waste treatment and could accumulate in sediments, but should not pose a significant risk because of their low toxicity to benthic organisms. Terrestrial testing demonstrated that soil needs to be saturated with these chemicals to produce adverse effects. Bioaccumulation potential for both polymers was extremely low. Use of these polymers does not appear to pose a significant risk to the environment, based on their low inherent toxicity. Received: 27 January 1997/Accepted: 9 September 1997  相似文献

The relatively short life cycles of harpacticoid copepods makes them appropriate animals for use in tests that rapidly assess the acute, sublethal, or chronic effects of sediment contaminants. In this study, four harpacticoid copepod species (Nitocra spinipes, Tisbe tenuimana, Robertgurneya hopkinsi, and Halectinosoma sp.) were isolated from clean marine sediments, and procedures for laboratory culturing were developed. Halectinosoma sp. was abandoned due to handling difficulties. For the remaining species, the influence of food type and quantity on life-cycle progression was assessed. A mixed diet, comprising two species of algae (Tetraselmis sp. and Isochrysis sp.) and fish food (Sera Micron) was found to maintain healthy cultures and was fed during laboratory tests. Water-only exposure to dissolved copper (Cu) showed that the times (range) required to cause 50% lethality (LT50) were 24 (22–27) h at 50 μg Cu/l for T. tenuimana; 114 (100–131) and 36 (32–40) h for 200 and 400 μg Cu/l, respectively, for N. spinipes; and 119 (71–201) and 25 (18–33) h for 200 and 400 μg Cu/l, respectively, for R. hopkinsi. 96-h LC50 (concentration causing 50% lethality) were also determined for adult N. spinipes exposed to cadmium, copper, zinc, ammonia, and phenol. A ranking system was generated based on the ease handling and culturing, rate of maturity, food selectivity and sensitivity to Cu. From this ranking, N. spinipes was determined to be the most suitable species for use in developing sediment-toxicity tests. The measurement of total reproductive output of N. spinipes during 10-day exposure to whole sediment was found to provide a useful end point for assessing the effects of sediment contamination.  相似文献

The effects of sublethal treatments (20% and 60% of LC50/24 h) with plant-derived molluscicides on the reproduction of the giant African snail Achatina fulica were studied. Azadirachta indica oil, Cedrus deodara oil, Allium sativum bulb powder, and Nerium indicum bark powder singly and binary combinations on reproduction and survival of A. fulica were investigated. Repeated treatment occurred on day 0, day 15, and day 30. These plant-derived molluscicides significantly reduced fecundity, egg viability, and survival of A. fulica within 15 days. Discontinuation of the treatments after day 30 did not lead to a recovery trend in the next 30 days. Day 0 sublethal treatment of all the molluscicides caused a maximum reduction in protein, amino acid, DNA, RNA, and phospholipid levels and simultaneous increase in lipid peroxidation in the ovotestis of treated A. fulica. It is believed that sublethal exposure of these molluscicides on snail reproduction is a complex process, involving more than one factor in reducing the reproductive capacity of A. fulica.

Recently, we showed for the wastewater of a large Swiss university hospital that primary DNA damage, assessed by a bacterial SOS repair assay (umuC test), could be largely assigned to a specific class of antibiotics, the fluoroquinolones (FQs) (Hartmann et al.[1998] Environ Toxicol Chem 17:377–382). In an attempt to confirm the significance of FQs for the bacterial DNA damaging effects in native hospital wastewaters, 25 samples from five German clinics were screened in this study by the umuC test. The results were compared to HPLC-derived concentrations of ciprofloxacin, an important member of the FQs. Ten samples (40%) were umuC-positive and ciprofloxacin concentrations ranged from 0.7 to 124.5 μg/L (n = 24). Primary DNA damage, as indicated by the umuC test, correlated strongly with ciprofloxacin concentrations in a logistic, dose-dependent manner (r2 = 0.896), almost irrespective of the use of S9 metabolic activation. The lowest observed effect concentration (LOEC) for ciprofloxacin was 5.2 μg/L (+S9) and 5.9 μg/L (−S9). Similar to our previous findings, these results indicate that positive umuC results in hospital wastewater are strongly dependent on the presence of fluoroquinolone antibiotics. In a second part of the study, previously generated Ames and V79 chromosomal aberration data of the same samples (Gartiser and Brinker [1995] in Umweltbundesamt Texte 74/95) were compared with the newly generated results. Neither the mutagenic effects detected by the Ames assay (8%, n = 25) nor the positive V79 results (46% n = 13) seemed to be caused by ciprofloxacin. Therefore, the Ames and V79 results suggest the presence of additional mutagens that are yet to be identified. Received: 8 March 1998/Accepted: 27 August 1998  相似文献

The xylenes (o, m, p), which are produced in large amounts and widely used, must be considered as environmental contaminants, as they have been identified in the atmosphere of many countries. Their acute and chronic toxicity in mammals is moderate. Mutagenic and teratogenic properties can be excluded. Carcinogenic potential has been at present inadequately studied. In man some disturbances are evident at the concentration of 45 ppm. Hepatic metabolism is a valid process of detoxification and its high rate limits the risk of accumulation of the xylenes in adipose tissue. Ecotoxicological data refer almost exclusively to water. No long-term tests have been made. However, the high volatility, elevated elimination, and the low factor of accumulation suggest the impact on aquatic environment should be limited. Xylenes are easily biodegraded by many microorganisms. Photoxydation is one of the main degradation processes, responsible for the disappearance of the xylenes from the atmosphere.  相似文献

Ecotoxicological evaluation of cork-boiling wastewaters   总被引:1,自引:0,他引:1  
Toxicity tests with Vibrio fischeri, Daphnia magna, and Lemna minor were used to evaluate acute and chronic toxicity of cork-boiling wastewaters and correlation analysis was performed with physicochemical parameters. Acute toxicity values (EC50) ranged from 2.3% to 24.2% in the Microtox test and from 4.4% to 29.5% in the Daphnia test. According to these values, 78% of the samples were classified as acutely toxic to the most sensitive species (V. fischeri). Significant correlation was obtained between EC50 and chemical oxygen demand, biochemical oxygen demand after 5 days, total organic carbon, tannin and lignin and total solids. No significant correlation was found between the two acute tests. The D. magna chronic test showed significant differences between all tested concentrations and the control, with an EC50 of 0.32%. An EC50 value of 26.0% was calculated for L. minor. For the analysis of cork-boiling wastewater toxicity and routine biomonitoring, the use of the Microtox test is suggested, to afford greater environmental protection.  相似文献

苯酚的遗传毒性研究   总被引:5,自引:0,他引:5  
通过小鼠骨髓染色体畸变和小鼠精子畸形试验,对苯酚的遗传毒性进行了观察.结果在50、100、200mg/kg体重3个剂量组中,染色体畸变率和畸变细胞百分率显著高于阴性对照组,且有统计学意义.在相同剂量范围内与阴性对照组相比,小鼠精子畸形百分率未有显著性差异。结合国外有关报道,可以认为苯酚是一种具有遗传毒性的诱变剂。长期职业接触可能会对作业工人产生远期危害.  相似文献
