地膜在大田作物生产中的应用增加了小麦籽粒中邻苯二甲酸酯（PAEs）的积累，对人体健康构成潜在风险。然而，不同旱区水稻籽粒中邻苯二甲酸酯含量的变化规律尚不清楚，邻苯二甲酸酯在水稻籽粒不同组织中的分布也尚未得到研究。采用田间试验方法，研究了3个省5个点2种处理（覆膜和不覆膜）下PAEs在谷物中的含量、分布及环境因子对其的影响。结果表明，小麦籽粒中PAEs总量（∑PAEs）为445 ~ 764 μg/kg，主要以邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二异丁酯（DIBP）和邻苯二甲酸二异丁酯（DBP）的形式存在。覆膜处理土壤和小麦籽粒中PAE总含量显著高于对照。覆膜对面粉和麸皮中邻苯二甲酸酯比例的影响因试验地点而异。对照组谷物PAEs与年平均气温呈显著负相关，覆膜处理土壤PAEs与麸皮PAEs呈显著正相关。研究结果对综合评价旱地小麦覆膜对粮食安全的影响具有重要意义。
The application of plastic film in field crop production elevated the phthalate esters (PAEs) accumulation in wheat grains, which poses potential risks to human health. However, the variation of grain PAEs contents in different dryland areas is not clear, and the distribution of PAEs in different tissues of grains has not been studied yet. In the present study, field experiments in five sites (three provinces) with two treatments (soil with and without film mulching) were carried out to study the concentration and distribution of PAEs in grains and the effects of environmental factors on them. Results showed that the total PAE concentration (∑PAEs) in wheat grains ranged from 445 to 764 μg/kg, mainly in the forms of di-(2-ethylhexyl)-phthalate (DEHP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP). Compared with control, total PAE concentrations in soils and wheat grains were significantly higher in treatments with film mulching. The effects of film on the proportion of PAEs in the flour and bran varied with experiment sites. Grain PAEs in the control groups presented significantly negative correlation with annual temperature, while there was a positive correlation between soil PAEs and bran PAEs in the film treatment. Results in this study are of great significance to comprehensively evaluate the effect of film mulching on grain safety in dryland wheat production.
