1. Ubiquity of Microplastics in Agricultural Soils
Microplastics infiltrate agricultural soils through multiple channels, including plastic mulch films, contaminated fertilizers, and irrigation with polluted water.
Their persistence is heightened by slow degradation rates, allowing them to accumulate over years.
A recent global study revealed that microplastics are now found in soils from China to Europe and the Americas, sometimes reaching concentrations that rival those in contaminated ocean environments.
This widespread presence underscores the urgent need to address their long-term impacts on soil health.
