They are useful to validate the pollutant load estimates to establish cause effect relations between diverse sources of pollution and water quality and also to assess the response of the river system to different management scenarios.
Finally, we only examined a single health outcome and thus other outcomes should be examined; while asthma exacerbation is robustly associated with ambient air pollution, this particular health outcome may be primarily driven by total pollutant load and, as such, may be less sensitive to pollutant composition than other health endpoints.
The SUSTAIN model developed two BMP cost-effectiveness curves for flow volume and pollutant load reductions.
The treatment plants, Mr. Pynn said, remove "94 percent of the pollutant load," far exceeding the requirements of the Clean Water Act.
This study estimated the appropriate pollutant load reduction from point sources in Kwangyang Bay, Korea, using an eco-hydrodynamic model.
Types of waste material and kind of pre-treatment prior to landfilling strongly influenced the pollutant load.
A major part of the pollutant load is transported during peak runoff periods after snowmelt or intense rainfall.
Landscape ponds are vulnerable to eutrophication due to continuous pollutant load from surface run-off and excessive fish feeding.
At all three sites, a clear negative correlation between pollutant load and the distance from the roadside could be found.
The pollutant load is influenced strongly by the rainfall regime, and can even double during extremely rainy years.
The development of efficient bioremediation techniques to reduce aquatic pollutant load in natural sediment is one of the current challenges in ecological engineering.
