Yes,eating organic foods is a great way to reduce the amount of pollutants in your body, but you can’t entirely escape pollution, no matter where you live.

Persistent organic pollutants, or POPs, are everywhere–in our food, soil, air, and water. They can travel far distances, so that even if you live in an area relatively free of the use of pesticides or industrial processes, pollutants will find their way to you.

In many instances, the levels of POPs found far from a source of pollution are significantly lower than the levels near the source. However, for some POPs, even low levels can be dangerous because they resist break down. When they get into your body, they stick around, accumulating in fatty tissues.

There is a global movement, involving over 150 countries, to eliminate some of the most dangerous of these POPs, which include pesticides, industrial chemicals, and their byproducts. Some of them have already been banned in the U.S.

全球超過150個國家發(fā)起運動，堅決杜絕使用一些危害甚大的持久性污染物：包括殺蟲劑、工業(yè)化學劑及相關副產(chǎn)品。美國禁止使用其中的一些。
