Global microplastic (MP) contamination and the effects on environment are well described. However, potential for MP consumption to affect human health remains controversial. Mice consuming ≈80 μg/kg/day of 1 μm polystyrene MPs via their drinking water showed no weight loss, nor were detected in internal organs.

The spatial distribution of microplastics in topsoils of an urban environment - Coimbra city case-study

Environmental Research, Journal Year: 2022, Volume and Issue: 218, P. 114961 - 114961

Published: Dec. 8, 2022

Due to their seemingly ubiquitous nature and links environmental human health problems, microplastics are quickly becoming a major concern worldwide. Artificial environments, such as those found in urban represent some of the main sources microplastic. However, very few studies have focused on occurrence soils. The aim current research was evaluate microplastic contamination soils from artificial natural land uses throughout Coimbra city, Portugal. Sixty-seven spaces ten use areas were evaluated. dumps, landfills, parking lots, industries construction areas, forests, parks, moors (wetlands), pastures agricultural areas. Microplastic extraction done by density separation. Quantification size measurements carried out using microscope. Polymer types identified μ-FTIR for 25% samples. content ranged 5 × 103 571 particles·kg−1, with mean 106 particle·kg−1. green park highest concentration (158 particle·kg−1) forest one lowest (55 particle·kg−1). landfill (150 particle·kg−1), industry (127 dump (126 levels microplastics. polymers detected polypropylene polyethylene, followed polyvinyl chloride rubber, sizes measured between 50 250 μm. Our results indicate that can contain higher amounts compared environment. This suggests easily transported through landscape retain Land planning may present an opportunity better control environments.
