摘要
目的 了解一次性使用塑料制品在使用过程中邻苯二甲酸酯的溶出情况。方法 对腹膜透析液、CPDA血液保存液、输液器、保鲜膜、一次性使用塑料袋和塑料瓶装水利用液液萃取、固相萃取分离富集、反相高效液相色谱法进行分析。结果 医用器具均检出邻苯二甲酸二异辛酯（DEHP）,最高溶出量达77.51μg/L,一次性使用塑料袋检出邻苯二甲酸二丁酯（DBP）,溶出量为91.45μpg/kg,保鲜膜和桶装水未检出邻苯二甲酸酯。结论 医疗器具中溶出的DEHP直接进入人体,其危险性应引起足够的重视。
Objective To explore the kinds and levels of phthalates leaching from disposable plastic products. Methods Samples of peritoneal dialysis solution, blood preservative solution, infusion instruments, preservative film, disposable plastic bags and water in plastic bottles were analyzed for phthalates by RP-HPLC after liquid-liquid extraction and/ or solid phase extraction. Results Di(2-ethylhexyl) phthalate (DEHP) was leached from all medical instruments, the maximum level of which reached 77.51μg/ L. Di-n-butyl phthalate was leached from disposable plastic bags, the level of which reached 91.45μg/ kg. Phthalates were not found in samples of preservative film and water in plastic bottles. Conclusion As DEHP leaching from the medical instruments might directly enter the human body, attention should be paid to its health hazards.
