Studies evaluating the relationship between microbes and human health at non-point source beaches are necessary for establishing criteria which would protect public health while minimizing economic burdens. The objective of this study was to evaluate water quality and daily cumulative health effects (gastrointestinal, skin, and respiratory illnesses) for bathers at a non-point source subtropica...
This paper analyzes effects of nonpoint source pollution on regulation optimal contracts in asymmetric information situation. We consider a continuum of agents (to formalize major characteristic of nonpoint source pollution) which pollute another agent (affected agent). We distinguish different forms of externalities and examine if it is always necessary to modify optimal contract of each respo...
In this article, novel gradient-based online learning algorithms are developed to investigate an important environmental application: real-time river pollution source identification, which aims at estimating the released mass, location, and time of a based on downstream sensor data monitoring concentration. The is assumed be instantaneously once. problem can formulated as non-convex loss minimi...
The excessive use of pesticides and fertilizers during agricultural production causes water pollution, which is an important type non-point source pollution (NSP). Large amounts harmful substances, such as nitrogen phosphorus, flow into surface along with farmland runoff, leading to eutrophication other problems. However, the pollutant discharge capacity different types cultivated land varies g...
Potentially harmful elements (PHE) occur both naturally from geogenic sources and from anthropogenic derived pollution. Anthropogenic sources can be further categorised into those derived from point sources. A point source is a single identifiable source which is confined to a very small area such as that arising from disposal of waste material or from an industrial plant. Diffuse pollution ari...
An atmospheric transport-chemistry model is applied to investigate the effects of source configuration in simulating regional sulphur deposition footprints from elevated point sources. Dry and wet depositions of sulphur are calculated for each of the 69 largest point sources in the UK. Deposition contributions for each point source are calculated for 2003, as well as for a 2010 emissions scenar...
