化学性污染的危害 常用农药污染 有机氯农药如六六六、滴滴涕等,曾因广谱、高效、价廉、急性毒性小而广泛使用。这些农药具有高度的化学、物理和生物学的稳定性,半衰期长达数年,在自然界极难分解。由于有机氯农药易溶于脂肪,在食品加工过程中单纯洗涤并不能去除,食用后容易在体内蓄积。有机氯的 The dangers of chemical pollution Commonly used pesticide contamination of organochlorine pesticides such as BHC, DDT, etc., had a wide spectrum, high efficiency, low cost, acute toxicity is widely used. These pesticides have a high degree of chemical, physical and biological stability, half-life of up to several years, extremely difficult to break down in nature. Since organochlorine pesticides are easily soluble in fat, they can not be removed by simple washing during food processing, and are easily accumulated in the body after eating. Organic chlorine
