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。
Objective To investigate the residues of phthalic acid esters (PAEs) in disposable plastic tableware in Chengdu and provide the basic data for evaluating the safety of their use. Methods Sixty samples of seven types of plastic food and drink were collected by stratified sampling in Chengdu. The residues of 16 kinds of PAEs were detected by gas chromatography-mass spectrometry. Results Diethyl phthalate, isobutyl phthalate, dibutyl phthalate and di (2-ethylhexyl) phthalate were detected in 16 kinds of PAEs. The detection rates were 6.7% (4/60), 10.0% (6/60), 46.7% (28/60) and 28.3% (17/60), respectively. The highest detection rates were 10.3, 6.4, 7.2 and 65.6 mg / kg, respectively. The remaining 12 PAEs were not detected in all samples. Conclusion The detection rate of some PAEs in this sampling sample is high, the maximum residue is large, and PAEs which are not used in food contact materials are detected. Therefore, it is necessary to further determine the specific migration of PAEs in different food simulants. To assess the impact on health.
