Abstract Drinking water source is an important guarantee of domestic for urban residents, which has been affected mainly by non-point pollution and aroused widespread concern in various countries. However, with the change underlying surface types, there are significant differences control strategies. In this study, two strategies were proposed typical conditions high-density built-up agricultur...
a r t i c l e i n f o This paper investigates the effect of governance on levels of water pollution for all industrial activities as well as by some specific industry category in a sample of OECD economies. Using an institutional ecological economic conceptual framework, the effects of several measures of governance are empirically examined. Our findings reveal that the rule of law, regulatory ...
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 ...
Fuel spillage during locomotive refueling is expensive, as is maintaining spill collection and containment systems, and waste treatment costs. The Association of American Railroads has developed the first standard for a locomotive refueling system for North American railroads. The locomotive fueling interface standard is an open, non-proprietary standard designed to prevent fuel spillage. Proto...
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 ...
environmental pollution consists of different types of pollutants in air, soil, and water. due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. air pollution in areas with oil and gas refineries nearby is an important problem. this study aims to survey the effects of gas refinery air pollutants on conocarpus erectus...
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...
