The source of heavy metals and its indication to the sediment transfer in the Hangzhou Bay

摘要

-Suspended matters are important carriers of heavy metals in the hydrocycle.In this paper, the field investigation , lab. experiment and "corresponding analysis" were made to study sources of the heavy metals and the transfer of suspended matters from the Hangzhou Bay.This conclusion shows that the contents of heavy metals in this area are the natural background values ; the distributions of heavy metals are controlled by the plume front.
