point source pollution

Agricultural non-point source pollution had no certain pollution source which had obvious potential, complexity and invisibility.

Soil phosphorus as agricultural non-point source pollution is one of the main factors which led to water pollution.

The result indicated that eutrophication would not be induced in Baiguishan Reservoir without point source pollution.

As an effective tool to control non-point source pollution, constructed wetlands are increasingly recognized by many countries.

Nitrogen (N) and phosphorus (P) are the two nutrients most often associated with mismanagement and non-point source pollution.

Therefore, the primary pollution control objective must be point source pollution and diffuse source of domestic wastewater in rural areas.

The situation on agricultural non-point source pollution was presented by the scene investigation, sampling and analysis in the laboratory.

Nitrogen fertilizer application inducing non-point source pollution is the main reason for groundwater contamination in the area.

Non-point source pollution is one of major reasons resulting in bad quality of water, so human has paid great attention to it.

The main causes of non-point source pollution are agrochemicals and waste from livestock and poultry and aquiculture .

Point source pollution comes mainly from industrial facilities and municipal wastewater treatment plants.

With the effective control of point source pollution, non-point source pollution becomes the main factor of water pollution.

The non-point source pollution is a serious problem in the water environment, with natural source developed and economic developing.

So the agricultural non-point source pollution has been considered as the main pollution source of eutrophication.

So, the excessive application of organic fertilizer had very big influence on agricultural non-point source, pollution.

When properly managed, wetlands can help prevent non-point source pollution from degrading water quality.

Non-point source pollution is the Nation's leading source of surface water and ground water quality impairment.

Agricultural non-point source pollution and runoff had close linearity correlation in the River watershed.

To calculate average perennial load of non point source pollution, a direct measurement method is developed.

The agricultural Non-Point source pollution is a ubiquitous environmental question in the whole world.

On the basis of the result, the control scheme of non-point source pollution in Huangpu River was put forward.

The agricultural non-point source pollution had become the main cause of rural environmental deterioration in China in recent years.

Non-point source pollution loading calculating.

It is worthy wide generalized a technics in the process of pollution treatment for agriculture and country non-point source pollution.

Agricultural non-point source pollution has become one of the most important sources of the world's water pollution.

So it is necessary to analyze and evaluate the cost and benefit of BMPs applied in agricultural non-point source pollution prevention.

And the importance of controlling agricultural non-point source pollution was expounded.

Control of agricultural non-point source pollution (AGNSP) is very important for improving water quality in watershed.

Therefore the study on non-point source pollution in Dagu watershed has very high theory value and realistic meaning.

Research work on agricultural non-point source pollution caused by soil erosion is a hot-point issue in recent 20 years.

With more control of point source pollution, nonpoint source pollution attracted more and more attention.

How to regulate "non-point source" pollution, such as pesticides from agricultural run-off, is a continuing, and harder, debate.

A project has been set up to study the non-point source pollution on Zhuhai city.
