面源污染 nonpoint source pollution
Nonpoint source pollution results from a wide variety of human activities on the land. Each of us can contribute to the problem without even realizing it.
土地的面源污染是人们各种各样的生产生活行为导致的不同来源的土地污染。我们每个人都可能在不知不觉间制造了某种污染源。
Most nonpoint source pollution occurs as a result of runoff. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with.
绝大多数面源污染的产生都与径流有关。雨水和融雪在地面流淌或渗入地下的过程中，可以吸附并携带上它们所接触到的任何一种污染物。
