邻苯二甲酸二(2-乙基己基)酯(DEHP)具有致畸致癌的作用,对塑料附近农田蔬菜进行了采样调查,应用GC/MS联机检测技术检测了12种蔬菜样品中DEHP的浓度水平。结果表明,按照EPA提出的人体每天限制剂量(RfD)为20μg/kg体重,则塑料工业区蔬菜DEHP含量已经超出安全标准。蔬菜不同品种累积DEHP的能力大不相同,其中冬瓜、茄子、毛豆、小白菜累积DEHP含量较高,为重污染蔬菜品种;番茄、小辣椒、丝瓜累积DEHP含量较低,在塑料厂周边农田种植和食用相对较安全。
Di-2-ethylhexyl phthalate (DEHP) has teratogenic and carcinogenic effects. Samples of farmland vegetables near the plastic were sampled. The concentrations of DEHP in 12 vegetable samples were detected by GC / MS on-line Level. The results showed that according to the EPA proposed human daily limit dose (RfD) of 20μg / kg body weight, the plastic vegetable DEHP vegetable industry has exceeded the safety standards. The ability of different varieties of vegetables to accumulate DEHP is quite different, among which, the content of DEHP in the winter melon, eggplant, soybean and cabbage is high, which is the heavy-polluted vegetable; the content of DEHP in tomato, pepper and loofah is low, And food is relatively safe.
