Scientists surveyed microplastic pollution across five types of land in a Chinese mining-agricultural city and found the highest levels in greenhouse farmland, with nearly 3,738 particles per kilogram of soil. Agricultural plastic waste, irrigation water, and fertilizers were identified as the main sources of contamination. The study shows that farming practices are major contributors to microplastic buildup in the soil that produces our food.
