【Abstract】 Phthalate acid esters(PAEs)are widely used as plasticizers and constitute one of the most frequently detected organic environmental contaminants. With the deterioration of the eco-environment in China during the past three decades, many studies on the occurrence of PAEs in greenhouse soil-crop systems and their risk evaluations have been conducted; this allows us to carry out a fairly comprehensive assessment of PAE contamination at a nation-wide scale. The sources of PAEs in agricultural soil mainly include agricultural film,chemical fertilizer, and sewage irrigation. We collected published data of PAE levels in soil-crop systems(greenhouse vegetable and open field planting systems)from the Pearl River delta, Yangtze River delta, Bohai rim, and northeast China. The concentrations of dibutyl phthalate(DBP)and di(2-ethylhexyl)phthalate(DEHP)in vegetables in the Yangtze River delta were higher than those in the Pearl River delta and Bohai rim, while the concentrations of DBP and DEHP in soils in northeast China were lower than those in other regions. The daily intake of PAEs was evaluated for different age groups from different regions of China, suggesting potential health risks. The control strategies for greenhouse PAE pollution are summarized and offer a scientific basis for the control of PAEs in greenhouses.更多还原
