Due to possible presence of hazardous substances in food products that may have deleterious effect to consumer's health, food safety aspects are still a worldwide concern. Hazardous substances could be manifested as food borne diseases. Heavy metal, like lead (Pb), is one of hazardous substances that may contaminate food products. This metal may contaminate food products through apparatus used for processing, air or water used during processing. Student snack foods (PJAS) are commonly prepared and dished in an opened place and hence will probably trigger a contamination of lead. As part of risk assessment, intake level of those foods and quantification of lead in those foods should be carried out to obtain exposure level of lead calculated as percentage of safe intake level (Tolerable Daily Intake, TDI). The aim of this study was to obtain exposure level of lead contamination from PJAS in SMA Kemah Indonesia 2 and SMK Bina Insan Mulia students calculated as percentage of TDI. Consumption data were collected through a survey applying food recalls 24 hours and food frequency questionnaire methods. PJAS samples were collected and purchased from selling location around the two schools and Pb was determined by atomic absorption spectrophotometer (AAS). From consumption •data and Pb concentration, exposure level of Pb to TDI can be calculated. The result of consumption survey revealed that there are six kinds of PJAS products mostly consumed by SMA Kemah Indonesia 2 students and five kinds, those consumed by SMK Bina Insan Mulia students. The mean concentration of Pb in the PJAS of SMA Kemah Indonesia 2 are respectively 0.8091; 0.5333; 0.4183; 0.6251; 0.4872; and 0.3034 ug/g, while those of PJAS of srvfl< Bina Insan Mulia are 0.4413; 0.3954; 0.4183; 0.4183; and 0.4643 ug/g, respectively. Taking into account the concentration of Pb in the PJAS of SMA Kemah Indonesia 2, and average intake of PJAS, total intake ofPb based on mean, median and modus of consumption are 71.08; 56.52; and 47.13 pg/day, while those of SMK Bina Insan Mulia are 62.83; 54.04 and 39.03 ug/day, respectively. Taking into account the TDI value of 3.6 gg/Kg bw/day and assuming the population body weight of 60, exposure level of Pb in SMA Kemah Indinesia 2, calculated based on mean, median, and modus of consumption, are 32.91; 26.17; and 21.82 %, respectively, while those of Slvfl< Bina Insan Mulia are 29.09; 25.02; and 18.07 %, respectively. Based on overall results, it was concluded, that level of Pb intake of students at the SMA Kemah Indonesia 2 and St•vK Bina Insan Mulia from PJAS are still lower than TDI value.
