Oil extraction may cause extensive environmental impact that can affect health of populations living in surrounding areas. Large populations are potentially exposed to oil extraction related contamination through residence in areas where oil extraction is conducted, especially in low and middle income countries (LMICs). Health effects among people residentially exposed to upstream oil industry ...

The study investigates water quality pollution impacts on urbanization by analyzing temporal and spatial characteristics of different water quality parameters, and simulating economic loss of water quality pollution in Xi’an, China from 1996 to 2003. Results show that organic pollutants were the greatest contributors of surface water quality pollution from 1996 to 2003. High values existed in p...

From 1 March to 31 May 1990, Bacillus cereus was recovered from 24 of 5,534 (0.49%) blood cultures and 22 of 1,088 (2.02%) other body fluid cultures. The rarity of this organism as a pathogen and comparison with previous baseline rates led to the conclusion that it was a pseudoepidemic involving some form of culture contamination. Generalized precautions taken without specific knowledge of the ...

The U.S. Environmental Protection Agency (EPA) has reported that over 45 percent of the nation's waterbodies are impaired and has identified nonpoint sources as the major contributors to water quality problems. Although federal and state government agencies have largely controlled pollution from point sources through infrastructure grants and permit programs, few statutes and regulations target...

As pollution incidents frequently occurred in the functional water areas of the Taihu Basin, Yangtze Delta, effective emission control to guarantee water quality in the Taihu Basin became the priority for environmental management. In this study, a new total emission control (TEC) method was proposed with an emphasis on the concept of water environmentally sensitive areas (WESAs). This method wa...
