The concentrations of COD, NO2-N, NH4-N, NO3-N, DIN, PO4-P of 48 water samples were monitored in Yangshan Port of 2020. The EI were used to evaluate the pollution degree and eutrophication status of water which show that nitric nitrogen(NO3−-N) is the main form of inorganic nitrogen(DIN), while the eutrophication in Yangshan Port area is mainly phosphorus limited, mainly moderate eutrophication. The EI in autumn is higher than that in spring. Correlation analysis shows that inorganic nitrogen(DIN) and phosphate radical(PO4-P) have good correlation, but no obvious correlation with COD. Meanwhile, inorganic nitrogen(DIN) and phosphate radical(PO4-P) have obvious negative correlation with salinity.

摘要

The concentrations of COD, NO2-N, NH4-N, NO3-N, DIN, PO4-P of 48 water samples were monitored in Yangshan Port of 2020. The EI were used to evaluate the pollution degree and eutrophication status of water which show that nitric nitrogen(NO3−-N) is the main form of inorganic nitrogen(DIN), while the eutrophication in Yangshan Port area is mainly phosphorus limited, mainly moderate eutrophication. The EI in autumn is higher than that in spring. Correlation analysis shows that inorganic nitrogen(DIN) and phosphate radical(PO4-P) have good correlation, but no obvious correlation with COD. Meanwhile, inorganic nitrogen(DIN) and phosphate radical(PO4-P) have obvious negative correlation with salinity.
