Microplastics contamination of soils
From Science Trends:  
So far, the majority of microplastics research has focused on the marine environment. Whilst the ocean is likely the ultimate destination for small plastic 
particles, the role of terrestrial environments should not be overlooked. Soils in agricultural and urban areas have the potential to be highly contaminated
with microplastic (particles between 0.1 m and 5 mm) and possibly also nanoplastic (particles measured in the nanometer range). These systems may represent
major environmental reservoirs of micro(nano)plastic, with several potential exposure pathways for organisms and human populations. For more see: https://sciencetrends.com/plastics-in-ou ...
