- W4220782512 abstract "<p>The occurrence, distribution, characterization and quantification of microplastics (MPs) and phthalic acid esters (PAEs) from the freshwater&#160;aquatic environment&#160;are not thoroughly explored in the Indian&#160;Himalayas&#160;despite concern over their adverse effects on human health and ecosystem. In this study, we have investigated the presence of MPs and PAEs in an aquatic system from&#160;Indian subcontinent. The MPs were detected in all water and sediment samples with abundances ranging from 02&#8211;64 particles/L and 15&#8211;632 particles/kg dw, respectively. The abundance of MPs, dominated by&#160;polyethylene&#160;and&#160;polystyrene, with the majority being fibres and fragments indicated that they were derived from plastic paints, boats or synthetic products. The concentrations of PAEs in the surface sediment samples varied from 06-357&#160;ng/g dw. The most abundant PAEs in the sediments were dibutyl&#160;phthalate&#160;(DBP) and di(2-ethylhexyl) phthalate (DEHP), since they were present in all the samples collected from the lake basin. The relatively higher abundances of MPs and higher concentrations of PAEs were generally found in the vicinity of areas impacted by anthropogenic activities. A clear correlation between the abundance of microplastics and PAEs concentration was observed suggesting that they are closely attributed to a single source. This study also provides an alternative approach to utilize the chemical additives in plastics as markers to trace the presence and distribution of MPs in the aquatic environment.</p>" @default.
