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。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.
