摘要:
于2019年10月,对江苏省(连云港、盐城和南通3市)近岸海域6个站位进行了1个航次的表层海水微塑料采样,监测分析了微塑料的粒径、丰度和组分分布情况。结果表明,江苏省近岸海域表层海水中微塑料污染广泛存在,监测站位检出率100%。微塑料粒径分布为0.02~4.80 mm,微米级微塑料占比最高(总体粒径占比83.4%),6个站位中15,24,36和37站位毫米级微塑料占比较高,呈现距离海岸越近毫米级微塑料占比越高的趋势。微塑料的丰度为0.06~1.18 个/m3,平均丰度为0.33 个/ m3,站位丰度排序为:36站位<26站位<37站位<24站位<15站位<59站位,其中站位最大丰度为站位最小的19.6倍。6个站位中,59站位的微塑料组分最多。所有微塑料组分中,乙烯醋酸乙烯酯共聚物(EVA)占比最高。微米级微塑料共有16种塑料组分,其中EVA占49.0%,聚氨基甲酸乙酯(PU)占24.3%;毫米级微塑料共有5种塑料组分,其中聚苯乙烯(PS)占比最高(43.3%)。

Abstract:
In October 2019, the surface seawater microplastics samples were collected from six stations in coastal waters of Jiangsu Province (Lianyungang, Yancheng and Nantong) during one voyage, and the particle size, abundance and component distribution of microplastics were monitored and analyzed. The results showed that microplastics pollution existed widely in surface seawater near the coast of Jiangsu Province, and the detection rate of microplastics was 100%. The size distribution of microplastics ranged from 0.02 mm to 4.80 mm, and the proportion of micron grade microplastics was the highest (83.4%). Among the six stations, the proportion of millimeter grade microplastic was highest at station 15 , 24 , 36 ,and 37, and the closer to the coast, the higher the proportion of millimeter grade microplastic was. The abundance of microplastics ranged from 0.06 to 1.18 n/m3, with an average abundance of 0.33 n/m3. The abundance of microplastics at all stations ranked as follows: station 36
