有机物生物降解性评价方法综述

Methods for the assessment of organic compounds biodegradability:A review

评价有机物生物降解性的方法和文献很多,但缺乏系统性介绍评价方法及指导方法选择的综述性文献.本文围绕有机物的生物降解性评价,简要介绍了评价有机物生物降解性的指示性参数及厌、好氧有机物生物降解性评价方法,着重介绍了评价方法选择的标准和原则,并详细分析了不同试验方法使用过程中产生有机物生物降解率差异的原因.最后,以世界经济合作与发展组织(OECD)制定的标准为例,全面介绍了该评价方法的选择使用过程并整合这一评价体系绘制了方法选择路线图,指出了各项试验方法的优越性.

There are plenty of methods used for the assessment of organic compounds biodegradability,but lack of comprehensive literatures in systematically introducing the assessment methods and guiding the choice of the methods.This paper briefly introduced the indicative parameters in assessing organic compounds biodegradability and the assessment methods of aerobic and anaerobic biodegradation,with the focus on the principles and criteria in the choice of the assessment methods,and analyzed in detail the reasons for the differences in the biodegradation rates of organic compounds when different test methods were adopted.Taking the standards established by the Organization for Economic Co-operation and Development（OECD） as an example,the process of choosing and applying the assessment methods was introduced,the systematic method-choosing route was integrated,and the advantages of the OECD standard methods were pointed out.
