Abstract

Increased mismanaged plastic has led to widespread microplastic (MPs) contamination in the marine environment. Our study investigates MPs across the inner, outer, and mangrove regions of the Kollidam River estuary on the east coast of India. Surface water and sediment samples at 18 locations were analysed for size, shape, colour, and polymer type. The average MP abundance in surface water and sediment was 2.42 particles. m⁻³and 1580 ± 705 particles. kg⁻¹d.w. respectively. The predominant polymer types observed were PP (40%), PE (26%), and PAc (24%). Medium-sized particles (1–2.5 mm) are more in surface water (44%), and small-sized (0.01–1 mm) particles dominate in sediment samples (50%). The most common MP shapes were fibres and fragments, with transparent MPs being the most frequently observed colour. The results highlight that the mangrove region acts as a potential sink for microplastic pollution.

印度东海岸科利达姆河口的微塑料污染：内河口、外河口和红树林河口区域的比较研究

越来越多的管理不当的塑料导致了海洋环境中广泛的微塑料（MPs）污染。我们的研究调查了印度东海岸科利达姆河口内、外和红树林地区的微塑料。我们对 18 个地点的地表水和沉积物样本的大小、形状、颜色和聚合物类型进行了分析。地表水和沉积物中的平均 MP 丰度分别为 2.42 微粒/米-3 和 1580 ± 705 微粒/千克-1d.w.。观察到的主要聚合物类型为 PP（40%）、PE（26%）和 PAc（24%）。中等大小的颗粒（1-2.5 毫米）在地表水中较多（44%），小颗粒（0.01-1 毫米）在沉积物样本中占多数（50%）。最常见的 MP 形状是纤维和碎片，透明 MP 是最常观察到的颜色。研究结果表明，红树林地区是微塑料污染的潜在汇集地。图文摘要

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
