The concentrations of Cr, Cd, Pb, Hg, and As in water, poultry meat, fish, vegetables, and rice plants obtained from the area adjacent to the Hazaribag tannery campus, Dhaka, Bangladesh, were estimated and compared with permissible levels established by the WHO and FAO and levels reported previously by other authors. The metal contents were in the following order according to the concentration in contaminated irrigation water: Cr?>?Pb?>?As?>?Hg?>?Cd. Mean concentrations of Cr, Pb, Hg, and As in irrigated water were above the permissible levels, whereas the results were below the permissible levels for Cd. The metal concentrations in poultry meat, fish, rice, and vegetables were in the following orders: Pb?>?Cr?>?Cd?>?Hg?>?As, Pb?>?Cr?>?Cd?>?As?>?Hg, Pb?>?As, and Cr?>?Pb?>?Cd?>?As?>?Hg, respectively. The mean concentrations of metals in poultry meat, fish, rice, and vegetables were much higher than the permissible levels. The trends of weekly intake of heavy metals (WIMs) from poultry meat, fish, rice, and vegetables were as follows: Pb?>?Cr?>?Cd?>?Hg?>?As, Pb?>?Cr?>?Cd?>?As?>?Hg, Pb?>?As, and Cr?>?Pb?>?Cd?>?As?>?Hg, respectively. WIMs for all the metals were lower than the provisional maximum weekly intake recommended by WHO/FAO and USNAS. 相似文献

ABSTRACT Residential satisfaction is a vital component of individual quality of life which has been explored by researchers from different perspectives. This study takes the stance to investigate residential satisfaction from sociodemographic standpoints. The purpose is to contribute to further research on residential satisfaction by exploring specifically the impact of age, gender and marital status on overall residential satisfaction and in more detail with components of residential satisfaction of residents living in apartment buildings in Dhaka, Bangladesh. Quantitative analyses of a survey of 204 residents living 59 apartment buildings in Dhaka was conducted to examine whether there is any relation between residential satisfaction with age, gender and marital status of the apartment dwellers. This study also examined if these sociodemographic characteristics had a moderator effect on some of the key components of residential satisfaction. Primary findings indicate that there exists a significant relationship between residential satisfaction with age, gender, and marital status. Further analysis revealed that the “Married” group was more satisfied than the “Single/Never married” group, senior people tend to be more satisfied than are younger respondents and females were more satisfied than males concerning overall residential satisfaction. This study concludes that potential sociodemographic differences among households in apartment developments in Dhaka should be considered for effective residential satisfaction and to create a socially sustainable living environment. 相似文献
