Distribution Characteristics of Petroleum in Water Quality of Hangzhou Bay
Based on the water quality monitoring data of 12 voyages in Hangzhou Bay from 2017 to 2019, the distribution characteristics of petroleum in the water quality survey project were analyzed. It was found that the content range of petroleum in the waters of Hangzhou Bay were 0.008~0.042 mg/L, 0.011~0.0...

| description | Based on the water quality monitoring data of 12 voyages in Hangzhou Bay from 2017 to 2019, the distribution characteristics of petroleum in the water quality survey project were analyzed. It was found that the content range of petroleum in the waters of Hangzhou Bay were 0.008~0.042 mg/L, 0.011~0.046 mg/L, 0.007~0.094 mg/L respectively, from 2017 to 2019, and the annual average content were 0.023 mg/L, 0.023 mg/L and 0.016 mg/L, all met the Class I sea water quality standard. In terms of seasonal change, the petroleum indicators in water quality were not obvious due to the influence of physical factors such as tidal current, sediment content and wind force, and they all belonged to fluctuations at low contents. In terms of interannual changes, the petroleum pollutants content were generally the same in 2017 and 2018, compared with the first two years, there was a significant decrease in 2019, with a certain downward trend. In terms of plane distribution, it mainly presented multipoint source distribution, and high value areas mainly appeared in coastal waters of Jiaxing and the south coast of Hangzhou Bay. Through correlation analysis and research, it was found that the content of petroleum was significantly negatively correlated with the suspended solids. The suspended solids in seawater had adsorption effect on petroleum pollutants, Thus the greater the mass of suspended solids in seawater, the lower the content of petroleum. |
