The application of plastic film mulching can greatly improve dryland productivity, while the release toxic phthalate esters (PAEs) from has generated concern. This study investigated effects mulched and residual on PAE concentrations in soil-crop system assessed risks to people eating crop products. PAEs concentration 0–25 cm soil layer farmland was 0.45–0.81 mg/kg, average 0.37–0.73 mg/kg non-mulched decreased by 19%. reached highest July, being 0.80–0.84 soil, also appeared gradually May at 0.62–0.74 October, were almost same non–mulched soils harvest time October 0.37–0.44 mg/kg. With amounts increasing 0 kg/ha 2700 (equivalent total amount after 60 years continuous mulching), no significant changes, 0.54–0.93 Maize (Zea mays L.) roots could absorb accumulate PAEs, bio-concentration factor (BCF) 1.6–2.3, stems, leaves, grains 79%–80% those 0.77–1.47 For ingestion maize or potato (Solanum tuberosum tubers grown containing 450–2700 kg/ha, hazard index (HI) less than 1, carcinogenic (CRs) 2.5 × 10−7–2.2 10−6, estrogenic equivalences 6.17–17.73 ng E2/kg. provides important data for risk management farmlands.
