Abstract:

The herbicide atrazine has caused high pollution risk to farmland soil in north China, and the effective in-situ remediation of atrazine pollution has become a research hotspot. Due to the advantages of high efficiency, low cost and being environment-friendly, microbial remediation technology has received widespread attention to remediate atrazine contaminated soil in-situ. In this paper, the effects of soil factors on the kinetics of atrazine adsorption-desorption, as well as the proliferation and vitality of functional microorganisms were summarized from the aspects of soil texture, pH, physical structure, nutrient level and so on. Meanwhile, some feasible suggestions and schemes were proposed to enhance the results of in-situ microbial remediation in the future. In conclusion, this paper can lay a foundation for the selection of bioremediation measures for contaminated soil according to local conditions, and provide theoretical guidance for strengthening microbial remediation of contaminated soil in-situ.

Key words: soil constituent, physicochemical property, bioavailability, adsorption-desorption
