摘要

Based on the monitoring results of environmental quality in Yueqing Bay during 2007 -2014, the current situation of environmental quality in the bay was analyzed and assessed. The results show that pH, DO, CODMn, petroleum, and heavy metals (Cu, Pb, Zn, Cd, Hg, As and Cr) in the seawater of Yueqing Bay did not exceed the second class standard of Seawater Quality Standard (GB 3097-1997), but inorganic nitrogen and reactive phosphate in the seawater of Yueqing Bay exceeded the second class standard seriously, and the water quality of the bay was in an eutrophic state； the standard index of evaluation factors of sediment quality was smaller than 1 , meeting the demands of sediment quality for environmental protection.
