摘要 目的评价天津市售牙膏中氟化物、砷、铅及微生物指标的安全性。方法在天津市区各大商场、商店采集牙膏60种,其中包括普通牙膏14种、药物牙膏18种、含氟牙膏28种(其中儿童用加氟牙膏6种,国产成人用加氟牙膏19种,进口成人用加氟牙膏3种),国产牙膏的产地分别为天津、北京、上海、广东等10余个省市。氟化物用氟离子选择电极测定,砷和铅用等离子发射光谱法,微生物指标按GB8372-1995《牙膏》方法检验。结果5种儿童用含氟牙膏水溶性氟化物含量为539~877mg/kg;3种国产成人用含氟牙膏水溶性氟化物含量为1582~1697mg/kg。1种进口牙膏铅含量高达43.09mg/kg,为限值的2.9倍。52种牙膏的细菌总数、粪大肠菌群、绿脓杆菌和金黄色葡萄球菌均符合国标要求。结论天津市售牙膏的卫生质量基本合格,个别国产加氟牙膏的氟化物以及进口牙膏的铅含量超标。 Objective To evaluate the safety of the levels of fluoride,arsenic and lead in toothpaste and the microbiological index of the toothpaste saled in Tianjin. Methods 60 tubes of toothpaste were sampled from the department stores and shops in Tianjin. The toothpaste samples included 14 tubes of commen toothpaste,18 tubes of medicated toothpaste,28 tubes of toothpaste blended with fluoride. Among 28 tubes of fluoride-adding toothpaste,6 tubes were specially used for children,19 tubes were domestic products for adults,3 tubes were imported for adults. All of the domestic toothpaste sampled were made in more than 10 cities and privinces such as: Tianjin,Beijing,Shanghai,Guangdong,etc. The levels of fluoride in toothpaste were determined by ion selective electrode,arsenic and lead were determined by inductively coupled plasma emission spectroscopy,the microbiological indexes were determined based on GB8372-1995 (toothpaste?雪. Results The contentes of soluble fluoride were 539-877 mg/kg for 5 tubes of fluoride-adding toothpaste used for children, 1 582-1 697 mg/kg for 3 tubes of domestic fluoride-adding toothpaste used for adults. The content of lead in an tubes of imported toothpaste was as high as 43.09 mg/kg,2.9 time the value of the national standard. The total count of bacteria,the count of fecal coliform,Paeruginosa,Staph aureus in 52 tubes of toothpaste sampled met the requirement of the related national standards. Conclusion The sanitary quality of 60 tubes of toothpaste sampled for this study saled in Tianjin was qualified in general,but very few had the sanitary problems in the aspects of fluoride excess in domestic fluoride-adding toothpaste and lead excess in imported toothpaste.
