Mapping Microplastics in Zarivar Lake's Water Column, Western Iran: A Study on Abundance, Composition, and Ecological Risk Assessment
The ubiquitous presence of microplastics (MPs) in marine ecosystems has raised global concerns due to their persistent nature, low density, and significant harm to marine environments life. Given the unique specifications and associated risks of MPs to unique organisms and different species inhabiting Zarivar lake, this study aimed to assess the distribution of MPs in water column of this large freshwater lake. Samples were collected from 15 stations across the lake and analyzed for MPs abundance, shape, size, color and polymer type using stereomicroscopy, SEM, and FTIR. Spatial analysis using ArcGIS was conducted to map the distribution of MPs across the lake. The mean abundance of MPs was 35.8 particles/L. The presence of MPs in samples of Zarivar lake was confirmed, with a predominance of fiber and fragment-shaped MPs of various sizes. Fourier Transform Infrared Spectroscopy (FTIR) analysis showed the presence of polymers such as polystyrene, polypropylene, polyamide, polyethylene terephthalate, polyurethane, and polyvinyl carbonate. The existence of these MPs poses a significant threat to this local ecosystem.
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.
