Abundance, distribution and characterization of microplastics in Tropical River Estuary, South East Coast of India
Rivers play pivotal role in transporting plastic litter into the ocean. The present study aimed to estimate microplastics (MPs) in Palar River (PR), that receives waste inputs of agricultural, industries, fishing, and domestic origin. Water and sediment samples were collected during low tide, at seven locations from inner check dam to mouth region. Highest concentration of MPs in water are observed at PR-6 (28.01 × 104 particles.km−2) and the lowest was recorded at PR-4 (2.6 × 104 particles.km−2). In sediment, highest count was detected at PR-1 (8.8 × 102 ± 226 particles.kg−1 d.w) and the lowest was recorded in PR-6 (2.5 × 102 ± 14 particles.kg−1d.w). MPs distribution in water is more in the outer mouth (PR-6) in comparison to inner region (PR-4). Fibres were dominating morphotype of MPs, comprised of 79.4% in water and 89.8% in sediment samples. According to size classification, the majority of particles (41.02% in water and 56.1% in sediment) were in the size range of 1 μm to 1000 μm. Characterization of MPs through Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy revealed that High Density Polyethylene (HDPE) is the dominant polymer indicating the use of plastic fishing nets and ropes along with the outfall from nearby industries may be the main contributor to the microplastic pollution in the river.
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.
