Microplastics contamination poses a serious threat to marine biota, so the current study was carried out to assess the incidence of microplastics in the gastrointestinal tracts of pelagic and benthic species collected from the six sampling sites along Thoothukudi region from January 2021 to December 2021. In the present study, benthic species (0.67 ± 0.14 MPs/indiv) showed a higher abundance of microplastics than pelagic species (0.53 ± 0.11 MPs/indiv). The dominance of microplastic shapes, sizes, colours and polymers found were comparable among both pelagic and benthic species, this being fibre (27.56% and 48.33%), 0.5-1mm (39.78% and 42.94%), blue (50% and 40.85%), and PE (46.24% and 48.18%), respectively. The present study showed that microplastics are ubiquitous in both habitats, which raises serious concerns for public health. Hence, measures focusing on reducing local emissions and plastic waste disposal should be implemented to control microplastic pollution in the marine environment.
微塑料污染对海洋生物群构成了严重威胁，因此开展了本研究，以评估2021年1月至2021年12月从图提科林地区六个采样点采集的浮游和底栖物种胃肠道中微塑料的发生率。在本研究中，底栖物种（0.67±0.14个微塑料/个体）显示出比浮游物种（0.53±0.11个微塑料/个体）更高的微塑料丰度。在浮游和底栖物种中发现的微塑料形状、大小、颜色和聚合物的优势情况相当，分别为纤维（27.56%和48.33%）、0.5 - 1毫米（39.78%和42.94%）、蓝色（50%和40.85%）以及聚乙烯（46.24%和48.18%）。本研究表明，微塑料在这两种栖息地中都普遍存在，这引发了对公众健康的严重担忧。因此，应实施侧重于减少本地排放和塑料废物处置的措施，以控制海洋环境中的微塑料污染。
