Abstract Objective To investigate the dietary lead exposure level among children aged 3 to 4 years in Jiading District, Shanghai Municipality, and assess the health risk caused by lead exposure, so as to provide the basis for the management of children's food safety. Methods Based on the 2023 Dietary and Health Status Surveillance Project in Jiading District, children aged 3 to 4 years from 12 streets (townships) in Jiading District were selected as the subjects using a multi-stage stratified random sampling method. The consumption frequency and daily intake of seven subcategories of four major food groups (beans, tofu), cereals (wheat, rice), meat (animal viscera), and aquatic products (mantis shrimps, bivalves) consumed by children over the past three months were collected using a food frequency questionnaire. Food samples were collected according to the food safety risk monitoring plan in Jiading District, and the lead content was detected. The health risks of dietary lead exposure among 3-4-year-old children were quantitatively assessed using the single-factor pollution index method, the Nemerow comprehensive pollution index method, and the margin of safety (MOS) method. Results A total of 143 3-4-year-old children were surveyed, including 69 boys (48.25%) and 74 girls (51.75%). A total of 317 food samples were tested, and lead was detected in all seven subcategories of food samples, with an overall detection rate of 77.29%. The detection rates of lead in bivalves and mantis shrimps of aquatic products were relatively high (98.75% and 100.00%, respectively). The mean lead content of various foods ranged from 0.003 4 to 0.090 7, with the highest level found in bivalves. The lead content of all food samples did not exceed the standard. The single-factor pollution index of seven subcategories ranged from 0.017 2 to 0.148 0, and the Nemerow comprehensive pollution index ranged from 0.116 5 to 0.424 4, both of which were less than 0.7. The MOS (mean) ranged from 0.000 3 to 0.003 9, with an overall MOS (mean) of 0.012 2. The MOS (P95) ranged from 0.005 7 to 0.055 9, with an overall MOS (P95) of 0.112 4, both of which were less than 1. Conclusions The lead pollution level in the diet among children aged 3 to 4 years in Jiading District is safe and clean, with an acceptable impact on food safety. However, the detection rate of lead is relatively high, and the main source of dietary lead exposure is aquatic products.
