中文摘要：

有机物-重金属复合污染物及其与土壤环境因子间的作用具有普遍性和多样性,其生物有效性与单一组分污染不同,单一污染理论常常无法解决复合污染问题。基于土壤有机物-重金属复合污染的生物有效性研究现状,从生物有效性变化类型、机制及影响因素3个方面,综述土壤有机物-重金属复合污染的生物有效性研究进展,并提出该领域研究中的不足和展望。

英文摘要：

The combined pollutant of organic substance and heavy metals, the interaction between the combined pollutant and soil environmental factors is universal and multifarious, and its bio-availability is different from that of the single component pollution. The single pollution theory usually fail to explain compound pollution phenomenon. Based on status quo of research on the bioavailability of the combined pollutant, from the variation types, mechanism, and influence factors of bio-availability, the research progress on the bio-availability of combined pollution of the soil organic substance and heavy metals was summarized, and the existing deficiencies and research prospects were put forward.
