农艺措施对土壤中酞酸酯消减的调控作用研究进展

酞酸酯是邻苯二甲酸的酯化衍生物,作为增塑剂或塑化剂被广泛应用于各种生活用品及塑料制品中,是目前世界上产量最大、应用面积最广的人工合成有机化合物.但近年来研究表明,酞酸酯是一类环境内分泌干扰物,在人和其他动物体内有着类似雌激素的作用,影响生殖系统功能,并且具有"三致"效应.我国设施土壤中酞酸酯污染较为普遍,不仅对土壤生态...

Regulation of Agronomic Measures on Dissipation of Phthalic Acid Esters in Soil: A Review

Phthalic acid esters, esterified derivatives of phthalic acid, are widely used in various daily necessities and plastic products as a plasticizer. They are currently a type of synthetic organic compounds with the largest production and the most widely used area. However, it has been discovered that phthalic acid esters are a type of environmental endocrine disruptors in recent years, showing estrogen-like effects in humans and other animals and affecting the function of reproductive systems, as well as exhibiting carcinogenicity, mutagenicity and teratogenicity for human. The pollution of phthalic acid esters in facility soils is relatively common in our country, which not only has potential harm to the soil ecosystem, but may also enter the interior of human body through food chains, thereby endangering human health. Therefore, it has become an important issue about how to accelerate the dissipation of phthalate pollution in farmland soil, which needed to be solved urgently by the national environmental protection department and agricultural department. The present paper reviews the domestic and foreign studies concerning the impact of agronomic measures on the dissipation behavior of phthalic acid esters from the aspects of water regulation, temperature regulation, application of exogenous additives, and cropping system management. In addition, the research in this field is prospected from three aspects: 1) to deeply and systematically decipher the chemical-microbiological regulation mechanisms of agronomic measures on the dissipation of phthalic acid esters in soil; 2) to establish the synthetical regulation technologies of agronomic measures for phthalate dissipation in soil, 3) to fully consider the combined effect of several phthalates or their intermediate metabolites when studying the regulation of agronomic measures on phthalate dissipation in soil. It is expected to provide a reference and expand new ideas for the enhanced bioremediation of phthalate contaminated soil through agronomic measures.
