采用显微红外光谱仪和共聚焦激光拉曼光谱仪对不同厂家、批次和品种的化学药品注射剂进行测试,对其不溶性微粒中的塑料微粒进行检测和分析。结果发现:样品中< 30 μm、30 ~ 100 μm和> 100 μm的塑料微粒的平均浓度分别为18.6、8.65、0.85个/L。塑料微粒的材质种类包括聚丙烯(PP)、聚乙烯(PE)、聚苯乙烯(PS)和聚对苯二甲酸乙二醇酯(PET),上述塑料微粒在注射剂中的平均浓度分别为21.05个PP/L、5.85个PE/L、0.3个PS/L和0.4个PET/L。该研究对化学药品注射剂不溶性微粒中的塑料微粒进行检测与分析,提示了化学药品注射剂的潜在风险。
Microplastics insoluble particles of chemical injections of different manufacturers,batches and varieties were detected and analyzed by microscopic infrared spectrometer and confocal laser Raman spectrometer.The results showed that the average concentrations of plastic particles with particle size of lower than 30 μm,30-100 μm and larger than 100 μm were 18.6,8.65 and 0.85 pieces/L,respectively.Meanwhile,the materials of plastic particles include polypropylene(PP),polyethylene(PE),polystyrene(PS) and polyester(PET),and the average concentrations of the above four plastic particles in the injections were 21.05,5.85,0.3 and 0.4 pieces/L,respectively.This is the first time to propose the detection and analysis of plastic particles in insoluble particles of chemical injections in this paper.Although the content of plastic particles is far below the standard value stipulated in the Chinese Pharmacopoeia,it suggests the potential risk of chemical injections.
