The influences of environmental factors on the abiotic methylation were studied. The biggest production of methylmercury was found after 2 days of incubation in presence of FA. The rate of production of methylmercury depends upon temperature. In presence of FA from sediment, the biggest production of methylmercury was found under 40℃. In presence of FA from soil, production rate increases with temperature. The biggest production of methylmercury was found when solution pH was 2 and 4 in presence of FA from sediment and soil, respectively. Increase in concentrations of inorganic mercury and FA solution causes an increase in the production of methylmercury. Under irradiation with ultraviolet ray, blacklight lamp as well as natural light, methylation is stimulated, especial for irradiation of ultraviolet light.

环境条件对汞甲基化作用的影响研究得出，在底泥和土壤FA体系中甲基汞产量均在反应2天后达到最大值；在底泥FA体系中汞的甲基化在反应温度为40℃时产量最大，而在土壤FA体系中，甲基汞产量在10～60℃之间随反应温度升高而增加；底泥和土壤FA体系中汞的甲基化分别在pH值为2和4时最大；甲基汞产量均随无机汞浓度和腐殖质浓度的增加而增加；紫外线、黑光灯和自然光照射都可促进甲基汞的生成，紫外线的作用尤其明显。
