Organic Pollutants


Yes,eating organic foods is a great way to reduce the amount of pollutants in your body, but you can’t entirely 1 escape pollution, no matter where you live.



Persistent 2 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 3 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.






选择有机食物大大减少了污染物进入体内,但是无论你身在何处都无法一点不受污染的侵害。



持久性污染物无处无在——我们的食物、土壤、空气、水。持久性污染物“跋山涉水”也会靠近你,即使你生存的地方没有使用杀虫剂或工业生产。



远离污染源的污染程度明显比污染源低很多。但是,即使是相对低的污染浓度也可能是安全隐患,因为污染物无法分解,当进入体内,滞留体内,堆积在脂肪组织。



全球超过150个国家发起运动,坚决杜绝使用一些危害甚大的持久性污染物:包括杀虫剂、工业化学剂及相关副产品。美国禁止使用其中的一些。
