Microplastic Contamination in Kollidam River Estuary, East Coast of India: A Comparative Study Across Inner, Outer and Mangrove Estuarine Regions
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.
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.
