Abstract

To access the distribution in fractions of heavy metals in paddy fields in Wenling city in Zhejiang Province, China, extensive sampling was carried out to identify spatial correlation and bioavailability to rice grown on these soils at the regional scale. The results showed that Cd in soil were predominantly association with exchangeable and Fe-Mn oxide fraction; while Cu, Ni, Pb and Zn with residual fraction. Most heavy metals studied in rice were significantly (P<0.01) correlated with exchangeable fraction, which is considered as readily bioavailability to rice.
