The Economics of Non-Point-Source Pollution [PDF]

open access: possibleAnnual Review of Resource Economics, 2011
Non-point-source (NPS) pollution refers to a form of pollution in which neither the source nor the size of specific emissions can be observed or identified with sufficient accuracy. In NPS pollution the ambient concentration of pollutants associated with the individually unobserved emissions is typically observed.

Pollution: Non-Point Source

2016
The biosphere is a life-supporting system to the living organisms. The detection of hazardous compounds in Antarctica, where these compounds were never used or no man has ever lived before, indicates how serious is the problem of long-range atmospheric transport and deposition of non-point-source pollution.

An Efficient Algorithm for Non-point Source Pollution Management Problems

Journal of the Operational Research Society, 1994
Summary: A dynamic programming (DP) algorithm is proposed for a class of non-point source pollution control problems. The formulation deals with the selection of a spatial distribution of management practices in such a way as to meet a control agency's sediment pollution target. The inherently combinatorial nature of these problems -- stemming from the

Modeling the non-point source pollution risks by combing pollutant sources, precipitation, and landscape structure

Environmental Science and Pollution Research, 2019
Traditional models of nutrient simulation usually focus on the pollutant sources and precipitation, lacking the quantification of landscape structure. We developed a new prediction model of pollution risks by combing pollutant sources, precipitation, and landscape structure, which was defined as the source-precipitation-landscape model (SPLM). The SPLM

Legacy pollution and our struggle to control non-point source pollution

Open Access Government, 2023
Legacy pollution and our struggle to control non-profit source pollution Changes to the natural landscape are pervasive. The construction of dams, alterations to river water courses, flood controls, farming, urbanization and deforestation all contribute to the current condition of our water resources.

Characteristics of Urban Non-Point Source Pollution in Suzhou City

2009 International Conference on Environmental Science and Information Application Technology, 2009
Urban non-point source (NPS) pollution of Suzhou City in different land use was investigated from Nov. 2006 to Sep. 2008. The results show that pollutants concentrations were very variable and dispersed for different sampling sites. The median values of Event Mean Concentrations (EMC) of COD, SS, NH3-N, TN and TP were 119-225, 93-188, 2.30-11.77, 6.35 ...

Simulating the evolution of non-point source pollutants in a shallow water environment

Chemosphere, 2007
Non-point source pollution originating from surface applied chemicals in either liquid or solid form as part of agricultural activities, appears in the surface runoff caused by rainfall. The infiltration and transport of these pollutants has a significant impact on subsurface and riverine water quality.
