“…One essential component of terrestrial ecosystems is soil, and they experience strong pollution pressure. Microplastic contamination of soils is being increasingly documented, with potential consequences for soil biodiversity and function [49,99,108,145,197,198]. However, the ecological impacts of microplastics in soils have been well reviewed [25,203].…”

Microplastic–toxic chemical interaction: a review study on quantified levels, mechanism and implication

et al. 2019

Current problem facing researchers globally is microplastics as well as toxic chemical pollution of the ecosystem. Microplastics carry toxic chemicals in the ecosystem serving as a vector for transport. In this study, a review of the literature has been conducted with the following objectives: (1) to summarize the concentrations of toxic chemicals such heavy metals and hydrophobic organic contaminants sorped on microplastics; (2) to evaluate their spatial distribution regarding adsorbed contaminant; (3) to discuss plausible mechanism by which microplastics adsorp or desorp toxic chemicals in the environment; (4) to discuss implications of their occurrence in air, water and soil media; and (5) to discuss the impact of ingested microplastics to human health. Microplastics are ubiquitous environmental contaminant. Concentrations of sorped toxic chemical varied by location which represents a local problem; industrialized areas (especially areas experiencing crude oil-related activities or have history of crude oil pollution) have higher concentrations than less industrialized areas. Ingestion of microplastics has been demonstrated in a range of marine and soil organisms as well as edible plants, thus possibly contaminating the base of the food web. Potential health effect to human is by particle localization, chemical toxicity and microbial toxins. We conclude by highlighting the gap in knowledge and suggesting key future areas of research for scientists and policymakers.

“…Most of the studies are structured very similarly using mechanical agitation within a salt solution for the detachment and density separation of MP. In two cases a foregoing and in six cases a subsequent additional oxidation of soil organic matter with H2O2 or other oxidants was applied, followed by lightmicroscopy and FTIR spectroscopy (LM+FTIR) for particle counting and identification of MP (Liu et al, 2018;Zhang and Liu, 2018;Han et al, 2019;Lv et al, 2019;Zhou et al, 2019;Chen et al, 2020;Ding et al, 2020;Huang et al, 2020;Zhang et al, 2020;Zhou et al, 2020). The 11 studies showed a median MP particle number of 1076 items kg -1 with a 25 % quantile of 78 items kg -1 , a 75 % quantile of 2500 items kg -1 and a maximum of 690000 items kg -1 .…”

“…This is the only study on traffic-derived soil MP in China, and is only among two studies worldwide. In a globally unique sampling, Lv et al (2019) investigated ponding as an entry pathway of MP to rice cultures. The respective concentrations in paddy fields with and without rice-fish co-cultures, often used systems of production in Southeast Asia, were very low (up to 18±6 items kg -1 ) between the rice-planting periods and more than twice as high in the planting season when the fields are ponded.…”

Abstract. Worldwide, microplastic (MP) has been commonly recognized as a threat for soil ecosystems. Terrestrial soils are widely contaminated by MP due to the application of sewage sludge and wastewater, plastic mulching, littering, the input of tire wear from roads and atmospheric deposition. Within the last decade, an increasing number of individual studies focused on item counts and masses of MP in different global soil environments. We reviewed these studies to achieve a representative picture of common degrees of contamination. The majority of the prospected agricultural and horticultural sites was exposed to sewage sludge and mulching film application and showed concentrations of
