To investigate the pollution level and development trend of lead in the preserved egg in our country.
By the national food contamination monitoring system and under the strict analysis quality control, the content of lead in the preserved eggs was analyzed according to the national standard method (GB/T 5009.12-2003) in fourteen provinces from 2000 to 2006.
All 1358 data on contents of lead in the preserved eggs were obtained during seven years, the total average was 1.782 mg/kg, the maximum was 334.0 mg/kg, P90 was 3.50 mg/kg, P95 was 7.397 mg/kg and P97.5 was 12.01 mg/kg, all exceeded 2 mg/kg of the national limit standard, and the rate of violated samples exceeded 10.0%. Analyzing from time, contents of lead in the preserved eggs were depressive from 2.994 mg/kg to 1.138 mg/kg year after year.
The lead contamination in preserved eggs was serious in whole country. It shows that the continuous work of monitoring and forewarning should be carried out to make the contamination of lead in preserved eggs to reduce year by year.
调查我国皮蛋中铅的污染水平及发展趋势。
通过国家食品污染物监测系统，在严格的分析质量控制下，按照国家标准方法（GB/T 5009.12 - 2003）对2000年至2006年期间14个省份的皮蛋中铅含量进行分析。
七年间共获得1358个皮蛋铅含量数据，总平均值为1.782mg/kg，最大值为334.0mg/kg，P90为3.50mg/kg，P95为7.397mg/kg，P97.5为12.01mg/kg，均超过国家限量标准2mg/kg，超标样品率超过10.0%。从时间上分析，皮蛋中铅含量逐年下降，从2.994mg/kg降至1.138mg/kg。
全国皮蛋铅污染严重。表明应持续开展监测和预警工作，使皮蛋中铅污染逐年降低。
