Advances on joint toxicological effect of mixture pollutants were reviewed according to development of various stages. Methods from qualitative to quantitative study of joint toxicological effect together with disadvantages and advantages were systematically introduced with focus on qualitative study and development of quantitative study. M -QSAR which draws lessons from QSAR of individual chemicals is still at primary stage, but is prospective for sustainable development in 21st century which can not only facilitate the development of environmental pollution chemistry but provide more reliable scientific approaches and theory basis to estimate ecology risk of pollutant.
