The purpose of this research was to explore the concept of an environmental racism claim through the use of several environmental
management tools. The EPAs Toxics Release Inventory, Cumulative Exposure Project, and the Los Angeles County Department of
Health Services' Hot Zone Census Tract Assessment were combined with racial and socioeconomic data to test claims that minorities
in South Central Los Angeles are disproportionately exposed to environmental lead. Multivariate analysis indicated that race
is strongly associated with the number of cases of elevated blood lead levels in South Central, irrespective of poverty status.
Proximity to point sources, a common focal point for studies of environmental racism, was not a contributing factor to health
outcomes. Proximity to transportation corridors was consistently the strongest indicator of environmental lead exposure, while
median home values were significantly and positively related to elevated blood lead levels. Implications for environmental
justice advocates and social and environmental scientists are discussed. 相似文献

Suburbanization and drought: A mixed methods vulnerability assessment in rainy Massachusetts 总被引:1,自引:0,他引:1
This paper presents evidence that water restrictions in suburbanizing eastern Massachusetts towns are becoming more common, controlling for climate. We then assess the relationship between these suburban droughts and residential development. Focusing on the suburbs of Boston, seven towns independent of the Boston water supply system were selected to represent differing levels of sprawl-style growth. Water restrictions are becoming more frequent in all of the towns studied, and models demonstrate that restrictions are increasing in duration, independent of climate. Interviews suggest that residential development is playing a central role in this increasing sensitivity to suburban drought, though other factors are also important. Long-term planning and integration of land-use planning and water management emerged as two key paths for attenuating the impacts of development. 相似文献

The microbiological and physico-chemical characteristics of the drinking water supplied by the Central Borehole at the University
of Benin, Ugbowo Campus were investigated. The investigation entailed assessment of the pH, turbidity, total suspended solids,
total dissolved solids, dissolved oxygen, temperature, salinity, conductivity, nitrate, nitrite, phosphate, sulphate, chloride,
N-nitroso compounds, cadmium, chromium, nickel, lead, zinc, manganese, iron, coliform count, BOD5 and COD of the water at the Central Borehole and at ten residential quarters. The assessment indicated that the water was
fit for drinking and other domestic applications. Results were also compared with WHO, EU and Nigeria FEPA standards. The
results showed that the pH values of the water (5.01–5.86) and total coliform count (1–2/100 ml) expressed as MPN were outside
the limits set by the WHO, EU and FEPA. The data also showed that the other water quality parameters assessed were within
WHO, EU and FEPA permissible limits. The results of ANOVA showed that significant changes occurred during distribution. 相似文献
