To investigate the level of lead in cereals and related products from Zhejiang market, and to provide the preliminary assessment.
Lead was detected in 4855 samples of cereals and related products during 2014-2019, food consumption data was taken from Zhejiang residents' consumption survey in 2015-2016.
The total detection rate of lead in cereals and related products was 59. 03%, and the acceptance rate was 99. 3% when compared to the national food safety standards(GB 2762-2017). The average lead level in cereals and related products was 0. 031 mg/kg, high mean level was found in millet with 0. 049 mg/kg, low mean level was in grain cans with 0. 020 mg/kg. The average dietary exposure to lead via cereals and related products was 0. 16 μg/(kg·d), and 0. 45 μg/(kg·d) for high consumer(P97. 5).
Lead in cereals and related products are at very low contamination levels, residents' average daily intake of lead from grains and products was low in Zhejiang Province, but measures are still needed to reduce lead in cereal products considering the adverse health effects of lead.
调查浙江市场谷物及相关产品中的铅含量，并进行初步评估。
检测2014 - 2019年期间4855份谷物及相关产品样本中的铅含量，食品消费数据取自2015 - 2016年浙江居民消费调查。
谷物及相关产品中铅的总检出率为59.03%，与国家食品安全标准（GB 2762 - 2017）相比，合格率为99.3%。谷物及相关产品中铅的平均含量为0.031毫克/千克，小米中铅平均含量较高，为0.049毫克/千克，谷物罐头中铅平均含量较低，为0.020毫克/千克。通过谷物及相关产品的铅平均膳食暴露量为0.16微克/（千克·天），高消费者（P97.5）为0.45微克/（千克·天）。
谷物及相关产品中的铅污染水平极低，浙江省居民从谷物及产品中铅的日均摄入量较低，但考虑到铅对健康的不良影响，仍需采取措施降低谷物产品中的铅含量。
