BACKGROUND Relatively few studies have examined the association between air pollution and stroke mortality. Inconsistent and inclusive results from existing studies on air pollution and stroke justify the need to continue to investigate the linkage between stroke and air pollution. No studies have been done to investigate the association between stroke and greenness. The objective of this study...

In many locations around the globe, large reservoir sustainability is threatened by land use change and direct pollution loading from the upstream watershed. However, the size and complexity of upstream basins makes the planning and implementation of watershed-scale pollution management a challenge. In this study, we established an evaluation system based on 17 factors, representing the potenti...

Contrary to the general trend of only a few actual trades occurring within point-nonpoint source water quality trading programs in the United States, two trading projects in the Minnesota River Basin, created under the provisions of National Pollutant Discharge Elimination System (NPDES) permits, have generated five major trades and numerous smaller ones. In this paper, these two projects are d...

OBJECTIVES To compare methods for defining the population at risk from a point source of air pollution. A major challenge for environmental epidemiology lies in correctly identifying populations at risk from exposure to environmental pollutants. The complexity of today's environment makes it essential that the methods chosen are accurate and sensitive. METHODS Environmental and mathematical m...

The use of nitrogen (N) fertilizer marked the start modern agriculture that boosted food production to help alleviate shortages across globe but at cost severe environmental issues and critical stress agroecosystem. This paper was aimed determining fate transport nitrite ammonia under future climate projections by adapting recommended land management practices are supposed reduce nitrate N in s...

The water quality of six important rivers in Haihe River Basin, including Yongding River, Luanhe North Canal, Daqing South Canal and Chaobai was evaluated. influence point source non-point on analyzed. causes environmental pollution the major were preliminarily revealed. results show that is good, impact discharge body small. Other are affected by different degrees pollution. Based analysis res...
