In this study,the pollution characteristics of microplastics in the wayer and sediments of Sanggou bay were investigated in December 2017,after the harvest of large-scale aquaculture,with the aim to study the effects of aquaculture activities and hydrodynamics on pollution characteristics and spatial distribution of microplastics in the bay. The results showed that the types of microplastics in the water and sediments of Sanggou bay were mainly fibers,fragments,films,foams and particles. The microplastic abundances in the water and sediments were 1.8 ~ 31.2 N/L,31.2 ~ 1246.8 N/kg,respectively. The average particle sizes of microplastics in water and sediments were 0.51 0.20 mm and 1.54 1.02 mm,respectively. The results of spatial distribution of microplastics in Sanggou bay showed that the high abundance area mainly appears in the inshore waters,and the abundance of microplastics tends to decrease from the inner areas of estuary to the outshore areas. The heterogeneity of microplastic abundance and spatial distribution in Sanggou bay is mainly affected by human activities such as aquaculture,living and shipping,as well as hydrodynamics. In the future,fine sampling and analysis are needed to fully understand the temporal and spatial distribution of microplastics pollution in the bay areas.   海洋微塑料输运的数值模拟研究进展 期刊论文 地球科学进展, 2019, 卷号: 34, 期号: 1, 页码: 72-83 作者:  张晨;  王清;  赵建民 收藏  |  浏览/下载：31/0  |  提交时间：2020/07/08 微塑料  数值模拟  输运  海洋动力过程  Microplastics  Numerical Simulation  Transportation Of Microplastics  Marine Dynamic Process   Severe Nitrate Pollution and Health Risks of Coastal Aquifer Simultaneously Influenced by Saltwater Intrusion and Intensive Anthropogenic Activities 期刊论文 Archives of Environmental Contamination and Toxicology, 2019, 卷号: 77, 期号: 1, 页码: 79-87 作者:  Jun Wu;  Xiaohu Wen 收藏  |  浏览/下载：4/0  |  提交时间：2020/06/17 GROUNDWATER NITRATE  LAND-USE  CONTAMINATION  SALINIZATION  WATER
