Method Yixiangyou 2115, Chuanyou 6203, F you 498, Deyou 4727, Shenliangyou 5814, Shenliangyou 862, Nei 4 youyuxiang No. 1, and Shuyou 217 were selected as test varieties, and the enzyme preparation (×500) was evenly spread on rice leaves at 6 000 mL/hm2, 5 d before and 5 d after heading stage, respectively. The arsenic, cadmium and mercury enrichments in various rice varieties were compared. Meanwhile, the content of arsenic, cadmium and mercury in Yixiang 2115, Chuanyou 6203, Deyou 4727, and F you 498 applying with the enzyme preparation at 0, 2700, 5400 and 9000 mL/hm2 were compared. Result Arsenic and cadmium contents tended to vary in rice varieties, and mercury contents were measured lower than the given limit value of 0.05 mg/kg in most cases. For the enzyme preparation, application dose had an insignificant impact on arsenic and mercury, but had a significant impact on cadmium, showing extremely significant difference among rice varieties and experimental groups and sign
