中文摘要：
目的调查成都市市售一次性塑料餐饮具中邻苯二甲酸酯类（phthalic acid esters,PAEs）的残留情况,为评估其使用安全性提供基础数据。方法对成都市市售一次性塑料餐饮具进行分层抽样,共获得7类60份样品,使用气相色谱-质谱联用法对其中16种PAEs的残留量进行检测。结果 16种PAEs中检出邻苯二甲酸二乙酯、邻苯二甲酸异丁酯、邻苯二甲酸二丁酯和邻苯二甲酸二（2-乙基）己酯,检出率分别为6.7%（4/60）、10.0%（6/60）、46.7%（28/60）和28.3%（17/60）;最高检出量分别为10.3、6.4、7.2和65.6 mg/kg。其余12种PAEs在所有样品中均未检出。结论本次抽检样品中部分PAEs检出率较高、最高残留量较大,且有不得用于食品接触材料的PAEs检出,故有必要进一步测定其在不同食物模拟液中的特定迁移量,以评估对健康的影响。
英文摘要：
Objective The aim of this study was to determine the content of phthalate in disposable plastic tableware sold on Chengdu market,and to provide primary data for safety evaluation. Methods Sample selection was based on stratified sampling. Sixteen phthalate compounds were investigated in 60 disposable plastic tableware,divided into seven groups. The analysis was performed by gas chromatography-mass spectrometry（ GC-MS）. Results In this survey,diethyl phthalate,diisobutyl phthalate,dibutyl phthalate and diethylhexyl phthalate were detected,while the other 12 phthalate compound were not. The positive rates of the four detected phthalate were 6. 7%（ 4/60）,10. 0%（ 6/60）,46. 7%（ 28/60） and 28. 3%（ 17/60） respectively,and the highest concentrations were 10. 3,6. 4,7. 2 and 65. 6 mg/kg,respectively. Conclusion The observed level of detection rates and maximum concentrations were relatively high in this survey. In addition,some subgroups of PAEs that were not allowed to use in food contact materials were detected. Therefore,the migration in different food simulant would be analyzed in the next step for further health outcome assessment.
