В главе представлена информация о Стокгольмской конвенции, этапах ее формирования и "грязной дюжине". Описаны физико-химические свойства, распределение в окружающей среде, метаболизм и деградация, токсичность основных стойких органических загрязняющих веществ (СОЗ), таких как хлорорганические пестициды (ХОП) и полихлорированные бифенилы (ПХБ). Ключевые слова: «грязная дюжина»; Стокгольмская конвенция; СОЗ; ХОП; ПХБ; физико-химические свойства; распределение в окружающей среде; метаболизм и деградация; токсичность. In the chapter, the "dirty dozen" of the Stockholm Convention and the stages of its formation are presented. The physical and chemical properties, distribution in the environment, metabolism and degradation, toxicity of the main persistent organic pollutants (POPs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are described. Keywords: "dirty dozen"; Stockholm Convention; POPs; OCP; PCBs; physical and chemical properties; distribution in the environment; metabolism and deg-radation; toxicity.

ABSTRACT Anaerobic microbial dechlorination is an important step in the detoxification and elimination of polychlorinated biphenyls (PCBs), but a microorganism capable of coupling its growth to PCB dechlorination has not been isolated. Here we describe the isolation from sediment of an ultramicrobacterium, strain DF-1, which is capable of dechlorinating PCBs containing double-flanked chlorines added as single congeners or as Aroclor 1260 in contaminated soil. The isolate requires Desulfovibrio spp. in coculture or cell extract for growth on hydrogen and PCB in mineral medium. This is the first microorganism in pure culture demonstrated to grow by dehalorespiration with PCBs and the first isolate shown to dechlorinate weathered commercial mixtures of PCBs in historically contaminated sediments. The ability of this isolate to grow on PCBs in contaminated sediments represents a significant breakthrough for the development of in situ treatment strategies for this class of persistent organic pollutants.

An automated high-throughput SPE method for selected persistent organic pollutants comprising 17 organochlorine pesticides, 22 polychlorinated biphenyls, 9 polybrominated diphenylethers and octachlorostyrene in human serum and plasma was developed.

Organic pollutants cause many environmental problems to our environment because of their toxicity, non-degradation and ability to long-range transport. The most common organic pollutants are known as persistent organic pollutants (POPs) and are known as hydrocarbons. Effective techniques for the removal of hydrocarbons and heavy metals from soil have drawn great attention. Remediation techniques represent one of the most important of these techniques because of their gentle impact on the environment. The study highlights numerous methods for Physical and chemical remediation techniques with explanation of the ability of some plants and agricultural wastes for remediation.

Organochlorine Pesticides (OCPs) is a kind of typical Persistent Organic Pollutants (POPs) with high toxicity, semi-volatility, environmental persistence and bio-magnification. Because of its large number of application in history, the residue level of OCPs in environmental media is rather high. This paper summarizes the existing status of the residue level and distribution of OCPs in China’s lakes in recent years, which is helpful to evaluate the pollution status of the OCPs in lake and provides a basis for effective governance.
