Description
Summary:[Display omitted] •Micro- and nano-plastics in agricultural soils represents a major environmental threat.•Standard methods for microplastic separation and detection are urgently needed.•Microplastics affect agroecosystem functioning by accumulating heavy metals or organic contaminants.•Plasticizers represent a major source of pollution within microplastics.•Adoption of biodegradable films will help reduce soil microplastic accumulation. It is now widely acknowledged that microplastic pollution represents one of the greatest anthropogenically mediated threats to Earth-system functioning. In freshwater and marine ecosystems the presence of large amounts of microplastic appears almost ubiquitous, with frequent reports of negative impacts on aquatic health. In contrast, however, the impact of plastic in terrestrial environments remains poorly understood. In agroecosystems, microplastics (particles
