Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

PLANTS, PEOPLE, PLANET, EarlyView.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found
