“…According to the data, the normal value of LDO in spring in the coastal waters of Quanzhou should be 6.37–8.24 mg/L, but the actual value of LDO measured was between 6.64 and 11.58 mg/L, which may be due to the proximity of the coastal water to urban and industrial waste water, the harmful substances reduce the oxygen consumption rate of activated sludge, resulting in the increase of LDO ( Chen et al, 2018 ). Or because of the inflow of wastewater containing strong oxidants, resulting in the oxidation of bacterial cell material, preventing their normal cell metabolism and even causing bacterial death, reducing the microbial demand for oxygen, and ultimately increasing the content of LDO in the water ( Phyu et al, 2024 ). From the increase of NO 3 – and NH 4 + contents in the water quality of coastal water, it can also be seen that the marine pollution caused by sewage discharge is aggravating ( Akarsu et al, 2020 ).…”

As a typical transitional area between the land and sea, the offshore area is subjected to the triple synergistic pressure from the ocean, land, and atmosphere at the same time, and has obvious characteristics such as complex and diverse chemical, physical, and biological processes, coupled and changeable environmental factors, and sensitive and fragile ecological environment. With the deepening of the urbanization process, the offshore area has gradually become the final receptions of pollutants produced by industry, agriculture, and service industries, and plays a key role in the global environmental geochemical cycle of pollutants. In this study, the Quanzhou Bay offshore area was selected as the research object. Sediment and water samples were collected from 8 sampling points within about 150 km of coastline in the Quanzhou Bay offshore area. 16s rDNA high-throughput sequencing method was used to investigate the variation rule of microbial diversity in the offshore area, and multi-parameter water quality analysis was carried out at the same time. The results showed that the distribution characteristics of microbial communities and water quality in the Quanzhou Bay offshore area showed significant differences in different latitudes and longitudes. This difference is closely related to the complexity of offshore area. This study can provide scientific support for protecting and improving the ecological environment of offshore areas.
