Microplastics Occurrence in Earthworm (Lampito mauritii) from the Mettur Dam, Southern India and Contamination Indices: Investigation and Indication
Ubiquitous pollution due to microplastics through the food chain is a major cause of various deleterious effects on human and animal health. This study aimed to investigate the existence and characterization of microplastics in earthworms (Lampito mauritii) collected from the Kaveri River, Mettur Dam, Southern India. The MPs were extracted from 40 earthworms by 10% of potassium hydroxide digestion medium. The extracted MPs were characterized using an optical microscope, Attenuated total reflectance-Fourier-transform infrared (ATR-FT-IR) spectroscopy, and field emission scanning electron microscopy-energy dispersive X-ray analysis (FESEM-EDX). Totally, 435 MPs are particles in the gut of the 40 earthworms, and four forms of MPs are fragments, films, threads, and pellets along with the smallest (0.1 mm) and greatest (1 mm) of MPs. ATR-FT-IR spectrum indicated three prominent polymer compounds, namely cellophane (CP), polyamide (PA), and polyarylether (PAE). The FESEM images observed that the majority of the microfibers had smooth surfaces and linear forms along with attachment of heavy metals. Our results highlight the preliminary insights into the presence of MPs in earthworm gut.
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.
