Social and health issues are now considered as an integral part of waste management system. Scavengers or waste pickers are the main victims in waste management sector. Objective of the cross sectional study carried out for a group of scavengers living in huts was to highlight the socio-demographic characteristic, working conditions and occupational health risks with main emphasis on relation of infectious disease prevalence and waste picking activity in Bahawalpur area. Of the 100 waste pickers and 100 non-waste pickers HIV was not detected in any participant, HBV was detected in 4 and 2 % and HCV in 28 and 6 % respectively. Considerable differences were observed in the detection rates of HCV (OR: 6.09, 95 % CI 2.4, 15.5; p = 0.000) and either markers (OR: 5.4, 95 % CI 2.35, 12.5; p = 0.000) in waste pickers compared to general population. The higher incidence of Hepatitis among waste pickers compared to non waste pickers is a function of their occupation, unhygienic living conditions, lack of immunization, ignorance and need of training regarding waste handling. 相似文献

The aim of this study was designed to determine the influence of welding fumes on oxidative stress in humans and the role of metals. A questionnaire was designed to collect information regarding personal characteristics, including age, weight, height, and medical history; life style such as smoking status and exercise habits; and occupational history such as working history, working environment, employment duration, and use of protective equipment. Body mass index (BMI) in kg/m2 was then calculated for each participant. Blood samples were also drawn to determine malondialdehyde (MDA) levels and various metals in plasma. Significantly higher plasma MDA (4.08 µg/L) was observed as compared to controls (1.61 µg/L). Blood metal analysis also showed elevated level of metals in welders for cadmium, chromium, lead,and nickel. Data indicated that workers occupationally exposed to welding fumes for prolong periods possessed higher metal levels associated with increased oxidative stress as evidenced by elevated MDA levels. 相似文献

Municipal solid waste management was studied for 1 year in a representative urban area of Lahore city for environmental sustainability. The effects of financial status of the household and the seasonal variations on generation rate and compositions of municipal solid waste (MSW) were determined. MSW generation rate and the economic status of the households were positively correlated (p < 0.05). Seasonal variations observed were significant only for organics (p = 0.001), plastics (p = 0.008) and food waste fractions (p = 0.009) in MSW. Response surface regression model developed and analysed by Minitab-15® showed that the interaction of season and different economic zones of the town on the MSW generation rate was non-significant (p = 0.334). Elemental and heating value analyses of the mixed organic fractions in kitchen waste had carbon 47.93%, hydrogen 6.20%, nitrogen 2.24%, sulphur 0.23%, oxygen 39.01%, and C and N ratio 27.78. Findings concluded that food waste was 56% of total MSW with 71.03% moisture content and a modest heating value of 5566 J/g. Existing temporary storage capacity of MSW is 51% of the total MSW generated considering the weighted MSW generation rate of 0.57 kg/person/day calculated in this study. Composting could be a possible final disposal option due to high moisture and organic content and can be studied in future research. Development of a transfer station, introduction of home composting programmes and awareness towards proper segregation and reduction of waste at the household level is suggested to attain sustainability in the MSW management system. 相似文献
