二(口恶)英类是对生态环境影响重大的持久性有机污染物,也是国际公认的环境内分泌干扰物质．我国目前加大了二(口恶)英类污染的控制力度,颁布了一些二(口恶)英类污染控制标准．但由于目前国内开展二(口恶)英类检测的单位还很少,我国主要污染源二(口恶)英类环境释放量及一些重要化学品中二(口恶)英类杂质的含量还不很清楚,由于某些化学品生产和使用已造成了一定程度的二(口恶)英类环境污染,并对人体健康构成威胁．本文按照美国国家环保局１９９６年修订的高分辨气相色谱/低分辨质谱分析二(口恶)英类标准方
Two (evil) British class is a major impact on the ecological environment of persistent organic pollutants, is also an internationally recognized environmental endocrine disruptors. At present, China has stepped up its efforts to control the pollution caused by two types of pollutants and promulgated some “two (evil)” British standards for pollution control. However, due to the fact that there are still only a few units for testing British (Evil) type in China at present, the quantities of E (English) and E (English) It is clear that due to the production and use of certain chemicals, a certain amount of environmental pollution has been caused and that this poses a threat to human health. This article according to the United States National Environmental Protection Agency in 1996 revised high resolution gas chromatography / low resolution mass spectrometry two (evil) British class standard side
