Distributions of COD and petroleum hydrocarbons and their relationships with occurrence of red tide in East China Sea

Abstract

Abstract: Based on the data of CODand petroleum hydrocarbons collected in the cruise from April 25 to May 2, 2002 in intensive red tide occurrence areas in East China Sea, the distribution of COD,and petroleum hydrocarbons and the eutrophication index(EI) were analyzed. The results showed that the EI and COD value were both high in coastal water, and decreased gradually away from shore. After the preliminary study on the relationships between correlative factors and occurrence of red tide, it was found that high EIand CODwere necessary. There would be great chances for the red tide to break out under conditions that the EIwas between2.5 and 15 and CODconcentration was between 0.8 to 1.4 mg稬^-1 in seawater, along with the favorable temperature and salinity.

Key words: East China Sea, Red Tide, COD, Petroleum hydrocarbons, Eutrophication
