摘要
选取江淮流域某地4镇的稻田土壤和稻米,对稻米中重金属铅、镉含量和稻田土壤中重金属铅、镉含量关系进行调查。结果表明,稻米中铅、镉含量多少与稻田土壤中铅、镉含量多少成正相关关系,稻米对重金属元素镉有生物富集作用。
The four rice planting area in jianghuai basin was chosen to investigate the correlation between Cd, Pb in paddy soil and in rice. The results showed that there was a positive correlation between Cd, Pb content in paddy soil and in rice. And there was a significant bioaccumulation between the rice and Cd.
