Abstract

The impact of microplastics has been a significant concern for human health and aquatic organisms. Last few decades, the understanding the microplastic occurrences in freshwater environments is very limited compared with marine environments. The present study aims to investigate the microplastic contamination in water and surface sediments of Vellayani Lake, Thiruvananthapuram, Kerala to assess the potential ecological risk status of the largest freshwater lake environment. The NOAA (National Oceanic and Atmospheric Administration) protocol was applied for this systematic assessment of plastic fibers. Totally, 95 microplastics were founded in both surface sediment and water samples. The mean value of microplastic in sediments and water ranging from 5.4 particles/kg and 4.1 particles/l, respectively. The morphology of microplastics suggests that the founded microplastic were dominated by fibrous and amorphous particles. The microplastics were derived into Vellayani Lake by the consequence of tourism and anthropogenic activities.

印度喀拉拉邦Vellayani湖微塑料的分布、特征和生态风险

微塑料的影响一直是人类健康和水生生物关注的重大问题。在过去的几十年里，与海洋环境相比，对淡水环境中微塑料存在的了解非常有限。本研究旨在调查喀拉拉邦Thiruvananthapuram Vellayani湖的水和地表沉积物中的微塑料污染，以评估最大淡水湖环境的潜在生态风险状况。NOAA（美国国家海洋和大气管理局）协议被应用于塑料纤维的系统评估。在表层沉积物和水样中共发现95种微塑料。沉积物和水中微塑料的平均值分别为5.4颗粒/千克和4.1颗粒/升。微塑料的形态表明，所形成的微塑料主要由纤维状和无定形颗粒组成。这些微塑料是由于旅游业和人类活动的结果而衍生到Vellayani湖的。
