Abstract

The environmental risks posed by microplastics (MPs) in soils have garnered global attention. Previous studies have mainly examined on the distribution of MPs in agricultural soils, which are heavily impacted by plastic films. However, knowledge about MPs pollution across diverse land-use types remains scarce. In the present study, we investigated the pollution of MPs in three types of soils (agricultural soil, industrial soil, and transportation soil). The results revealed that 100% of the soil samples tested contained MPs, with concentrations ranging from 50 to 5600 items/kg. Agricultural soils exhibited the highest abundance of MPs, while transportation soils had the lowest. Fragments and small-sized particles (0–1 mm) were the most prevalent types and sizes. Polypropylene (PP) and polyethylene (PE) accounted for 45.40% and 28.85% of the total polymer content, respectively. The primary colors of MPs were white and transparent (52.70%), followed by black (23.56%). Variations in plastic debris colors may offer clues about the sources of plastic pollution. Three evaluation methods were applied to evaluate the ecological risks of MPs in soils. The findings indicated that industrial and agricultural areas posed greater risks, underscoring the need for more targeted pollution management strategies for MPs.

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.
