Risk Assessment of Agricultural Plastic Films Based on Release Kinetics of Phthalate Acid Esters

Plastic films have become an integral part of fruit and vegetable production systems, but their release of phthalate acid esters (PAEs) is a threat to human health. The release kinetics of PAEs and measures of risk are still not well understood. We investigated 50 agricultural films, with concentrations ranging from 2.59 to 282,000 mg kg–1. The seven commercially available film types included were polyvinylchloride (PVC), metallocene...
