中国医学科学院卫生研究所于1980年组织成立了全国生物监测协作组,监测项目之一是探索有机氯化合物在人乳中的蓄积水平。为确保分析数据的准确、客观,该组织要求各参加实验室完成并通过AQA(分析质量保证),即合成奶样中未知含量的有机氯农药与多氯联苯的分析考核。为此,我们对国内外有关方法进行了反复摸索探讨,结合现有仪器设备 Chinese Academy of Medical Sciences Institute of Health organized the establishment of a national collaborative biological monitoring team in 1980. One of the monitoring projects is to explore the accumulation of organochlorine compounds in human milk. To ensure accurate and objective analysis of the data, the organization asked participating laboratories to complete and pass AQA (Analytical Quality Assurance), an analytical assessment of organochlorine pesticides and PCBs with unknown levels in synthetic milk samples. To this end, we have repeatedly explored the methods at home and abroad, combined with existing equipment
