European farmland could be biggest global reservoir of microplastics, study suggests

Sewage sludge is commonly used on agricultural land as a sustainable and renewable source of fertiliser throughout European countries, in part due to EU directives that promote the diverting of sewage sludge away from landfill and incineration and towards energy production and agriculture.

“Our results highlight the magnitude of the problem across European soils and suggest that the practice of spreading sludge on agricultural land could potentially make them one of the largest global reservoirs of microplastic pollution,”
