【摘要】 为了解塑膜袋中的PAEs对番茄的污染程度。以套塑膜袋番茄为试材,采用GC-MS法测定番茄皮和番茄肉中的11种PAEs化合物。结果表明,套塑膜袋番茄皮中检出6种PAEs,浓度在0~2.70 mg/kg范围内;茄肉中含有4种PAEs,浓度在0~0.04 mg/kg之间。套纸膜复合袋番茄皮中检出5种PAEs,含量在0~5.17 mg/kg之间;茄肉中检出2种PAEs,浓度为0~0.07 mg/kg。可见塑膜袋中的PAEs对番茄有一定污染,主要富集于番茄皮部分,番茄肉中PAEs浓度较低。更多还原

【Abstract】 To investigate the pollution levels of PAEs in Tomato bagged with plastic film bag, Tomato samples bagged with different plastic bags were chosen as subjects. By using GC-MS, 11 PAEs compounds in peel and pulp were determined. Results showed that 6 PAEs were detected in tomato peel bagged with single plastic bag, the contents were 0-2.70 mg/kg; 4 PAEs were detected in pulp, which between 0-0.04 mg/kg. The contents of 5 PAEs in tomato peel bagged with paper-film composite bag were 0-5.17 mg/kg, while the 2 PAEs in pulp were 0-0.07 mg/kg. It was concluded that PAEs do exist in tomato bagged with plastic film bag,which mainly enriched in the part of the tomato peel, with lower concentrations in the pulp.更多还原
