Abstract: The results show that heavy metal pollution in sea water along the estuary of Jiaozhou Bay is mainly from the discharge of industrial wastewater nearby the estuary. The heavy metals content in marine organisms is affected not only by the content of heavy metals in sea water, but also by temperature. Benthons have a higher heavy metals content than fish, and marine organisms enriche more copper than other heavy metals.
