Rationalization of water quality monitoring locations under spatiotemporal heterogeneity of diffuse pollution using seasonal export coefficient.

Journal of Environmental Management, 2020
Water quality is continuously changing because of anthropogenic origin of point and diffuses (non-point) pollution sources. Most of the time diffuse sources are not considered for rationalization of sampling sites as their accurate estimation is tedious ...

Assessment of real and perceived cost-effectiveness to inform agricultural diffuse pollution mitigation policies

, 2020
Diffuse water pollution is a major problem in many agroecosystems, especially in irrigated areas linked to ecosystems of high ecological value. Pollution abatement policies imply the modification of agricultural measures and are usually rejected by ...

The problem of agricultural 'diffuse' pollution: Getting to the point.

Science of the Total Environment, 2019
Despite introduction of legislation such as the EU Nitrates and Water Framework Directives (Directives 91/676/EEC and 2000/60/EC respectively), agricultural practices are often still regarded as a major factor in poor water quality across many EU member ...

Diffuse nitrogen pollution in a forest-dominated watershed: Source, transport and removal

, 2020
Along with gradually controlled point source discharges, diffuse nitrogen pollution has become an important cause of eutrophication. Diffuse nitrogen export from forests is an inherent characteristic, and increasing human disturbance aggravates this ...

Riparian forests mitigate harmful ecological effects of agricultural diffuse pollution in medium-sized streams.

Science of the Total Environment, 2019
Agricultural pollution persists as a significant environmental problem for stream ecosystems. Uncultivated buffer zones or reforestation of riparian zones are advocated as a key management option that could compensate the harmful land use impacts.

Natural Wetlands Treating Diffuse Pollution

2006
This chapter presents a case study to assess the temporal and spatial hydraulic and biochemical functioning of groundwater-fed ditch ecosystems and their contribution to the overall catchment and particularly nutrient dynamics of a riparian peatland located in the River Eider Valley.

Enhanced diffusion of pollutants by self-propulsion

Physical Chemistry Chemical Physics, 2011
Current environmental models mostly account for the passive participation of pollutants in their environmental propagation. Here we demonstrate the paradigm-changing concept that pollutants can propagate themselves with a rate that is greater than the rate for standard molecular diffusion by five orders of magnitude.

Understanding the risks from diffuse pollution on wetland eco-systems: The effectiveness of water quality classification schemes

, 2020
Eco-environmental safety and health is an important concept for the protection of flora and fauna in the wetland eco-system. Identifying impacts of human activities on wetland ecology and risk factors of environmental decline have become significant ...

Pollution by Diffusive Processes

1973
The most serious types of pollution are those following the release of the pollutant from points within or on the boundary of a gaseous or liquid medium. The problems to be considered in this paper relate to the determination of the distribution of the pollutant within the medium and along the boundary of the medium.

The ecohydrological approach, SWAT modelling, and multi-stakeholder engagement - A system solution to diffuse pollution in the Pilica basin, Poland.

Journal of Environmental Management, 2019
The reduction of diffused nutrient pollution from agriculture is one of the defining challenges of our time, demanding system solutions. A nitrogen and phosphorus (N&P) reduction strategy at the catchment scale is the most realistic and effective long ...
