生活垃圾填埋场构建临时道路,通常采用碎石加土工布、钢板、建筑垃圾等,通过对采用土工格栅构建临时道路的试验,比较不同材料构建临时道路的优缺点,得出填埋场临时道路采用双层土工格栅是可行的,对车辆的稳定性、卸点的安全性是其它材料难以达到的,可作为临时道路的首选材料。 相似文献

生活垃圾发酵填埋处理技术是针对目前我国经济发展现状及垃圾及垃圾处理出现的问题而提出的一种新的处理方法。将传统的有机垃圾发酵处理技术与填埋技术结合起来,将垃圾处理五城市建设结合起来,把垃圾中可隐解有机物在人为条件下快速生物降解转化为腐殖质并还原于土壤,在较短内实现生态恢复,使拉圾填埋土地尽快成为建筑用地。 相似文献

Assessment of Environmental Health Children’s Population Living in Environmental Injustice Scenarios
Gabriela Domínguez-Cortinas Enrique Cifuentes Edna Rico Escobar Fernando Díaz-Barriga Martínez 《Journal of community health》2012,37(6):1199-1207
We conducted a cross sectional study, involving 145 children randomly selected from three different socioeconomic locations. We selected social, environment and health indicators and measured the prevalence and prevalence odds ratios. Children from the brick producing site (segregation index 5), are exposed to high levels of multiple toxic agents, and showed the highest morbidity rates and malnutrition, anemia, dental fluorosis, and the lowest IQ, followed by children from municipal garbage dump (segregation index 4), where we detected the highest prevalence of dermatological and enteric diseases. Children from the Central Zone (segregation index 2) showed the lowest rates of malnutrition and higher IQ than the other two groups. A unified vision of social, health and environmental indicators opens the possibility of novel intervention programs and a legal framework that specifically protect children against environmental exposures. 相似文献

Background
Patients with diabetes on insulin therapy use sharps (e.g., needles) on a regular basis and a considerable proportion of them, within their home environments. These sharps and other bloodstained materials, if not disposed of appropriately has the potential to be a public health hazard.Objective
Our objective was to explore the practices related to sharps disposal among patients with diabetes from North Colombo Teaching Hospital (CNTH), Ragama, Sri Lanka.Methods
We conducted a cross-sectional study on 158 patients with diabetes from the CNTH. Patients had to use sharps for the daily management of their disease for inclusion into the study group. Data were collected on sharps disposal practices using an interviewer-administered questionnaire. Clinic records were also used as a secondary data source.Results
Most patients, 153/158 (96.8%) used syringes to inject insulin. Forty-three patients (27%) involved others (e.g., family) when disposing of sharps. Used sharps were commonly disposed to the household garbage bin by 66 participants (41.7%). Other methods used for sharps disposal were: sharps container, toilet pit, household garbage dump and indiscriminate measures. Importantly most patients, 147 (93%) had received no information on how to dispose of sharps after usage.Conclusion
Patients commonly used unsafe practices in home-based sharps disposal. These included disposing of in the household garbage bin, burning sharps in the household garbage dump and disposing of into the common garbage dump of the community. Being male and being >?60 years of age was associated with a higher dependence on family members for sharps disposal. Patient education and public resources for sharps handling can help improve this situation.13.

The association of infantile diarrhoea with the presence of garbage in the environment was investigated in Canabrava, a peripheral neighbourhood of Salvador, northeast of Brazil. A cross-sectional study was conducted with all the 184 children aged less than two years residing in Canabrava, which is located close to the city garbage dump. Variables selected for study included the method used for the disposal of excrement, type of floor, mother's education, unemployment of the head of the family, regularity of the water supply, presence of toilet, storage of garbage inside the house, age, gender, duration of breastfeeding, and the number of people per room. The estimated prevalence of diarrhoea was 21.2%. Exposure to garbage in the environment was found to be the most important factor associated with diarrhoea (adjusted odds ratio [AOR] = 3.98, 95% CI 1.56-10.13). Other important variables were the mother's education (AOR = 2.79, 95% CI 1.09-7.13), maternal breastfeeding (AOR = 2.30, 95% CI 1.05-5.04), and unemployment of the head of the family (AOR = 2.09, 95% CI 0.93-4.69). These findings indicate the necessity of adopting solutions in the public domain and of intersectorial policies for the reduction of diarrhoea. 相似文献

摘要:目的 分析江苏省农村地区生活垃圾、生活污水处理、家庭饮水习惯、农药使用与防护及土壤监测现状。方法 按照分层随机抽样的方法从江苏省全部13个省辖市中选取65个乡镇260个村1 300个农户。调查生活垃圾、生活污水、家庭饮水习惯,农药使用与防护情况,并进行土壤监测。结果 在260个行政村中,8.08%的调查村生活垃圾为随意堆放,21.54%的调查村生活污水为直接排放;在1 300户调查户中,居民饮用水类型以集中式供水为主(占91.69%),饮水习惯以喝开水为主(占86.23%);在823户使用农药的调查户中,54.07%的调查户选择现用现买不储存农药,有74.00%的调查户选择将废弃包装药瓶(袋)堆放在田边或垃圾堆,47.79%的调查户选择在施药时仅采用穿长袖衣、裤的单一保护方式,仅有16.71%的调查户在施药时采用全面的保护措施;高淳县、吴江区、丹阳市、姜堰市存在土壤镉含量不合格的情况。结论 2013年江苏省农村地区家庭饮水习惯和土壤监测结果况较好,生活垃圾随意堆放和生活污水直接排放的情况时有发生,大部分农户在使用农药时的防护方式较单一,废弃包装药瓶(袋)处置不规范。 相似文献

AbstractIn Tomatlán, a small city on the Mexican Pacific Coast there is a tolerance zone in which a group of sex workers, separated from the rest of the city by a garbage dump, offer their services to local men. The women present themselves materially and symbolically as agents of regulation with respect to male sexuality, itself constructed as overwhelming and insatiable, which, were it not for services provided by the sex workers, would threaten the family-based social order. Through in-depth interviews with 19 sex workers and 5 municipal officials, this paper discusses how the sex gender system results in a series of borders that are both geographical and subjective. Such borders have to do with periphery and control, body and intimacy, and the boundaries of animality. 相似文献
