Causes of pollution in Wenchang River

The pollution of the Wenchang River is caused by human activities, agricultural production and natural factors.

1. Due to the impact of urban development and production and living activities, a lot of industrial wastewater, domestic sewage, garbage and other garbage are discharged into the Wenchang River, causing river water pollution. The failure of residents along the river to develop good garbage classification and disposal habits has also exacerbated river pollution.

2. In the river basin, agricultural chemicals such as pesticides and fertilizers are used on cultivated land and farmland, and these chemicals are easily washed away by rainwater into the Wenchang River, causing adverse effects on the quality of the water body.

3. Extreme weather (such as heavy rains, floods, etc.) may cause the Wenchang River to overflow, causing a large amount of soil and debris to enter the water body, further exacerbating the water pollution problem.

The pollution of the Wenchang River is the result of the interweaving of multiple factors. Measures need to be taken to protect the ecological environment and reduce pollution sources.
