Microplastic contamination is ubiquitous in riparian soils and strongly related to elevation, precipitation and population density
2021
Abstract Although environmental research has recently begun to focus on the ubiquity of microplastics in terrestrial systems, there is still lack of comprehensive data which describe microplastics levels in soils and the factors influencing the distribution of this contaminant. Here, we show that microplastics contamination (3877 ± 2356 p kg1) is omnipresent in numerous soil samples collected along the Yangtze River. Subsoils (4005 ± 2472 p kg1) showed higher levels of microplastics than topsoils (3748 ± 2301 p kg1), while polyamide (32%) was the most commonly found polymer in the samples. Small microplastics particles (
