Pollution monitoring of marine organisms grown in the Zhoushan Sea of China

The sustainable regeneration of the biggest fishery resource in the Zhoushan Sea area of China has been adversely affected in recent years. Wastewater discharged into the marine ecosystem is the main source of pollution. Affected organisms such as hairtail prawn, jellyfish, crab, laver and kelp were monitored, and the contributions and fluxes of three sort of pollutants(oils, Cr and phenol) from the expansion of rural enterprises in the Yangtze River valley, the Qiantang River valley, the Ningbo coastal area and the Zhoushan islands were calculated. More than 16 chemical pollutants were jointly responsible for the decrease in the yield and quality of marine organisms. Furthermore, combined contamination effects and their joint toxicity differed between summer and winter, because they were varied with different temperature, salinity, pH and E h.
