Dietary Exposure

Brief summary

The aim of this study is to evaluate the occurrence of chemical hazards exposure in the Singapore population and assess their association with food consumption.

Detailed description

Human biomonitoring is an exposure assessment approach with the potential value-add supplementation to existing sources of information for regulatory risk assessments and for supporting food safety policies. The collaboration involving academic partners from the sciences and public health disciplines to quantify the in vivo chemical exposure of chemicals will take reference from the findings in the Singapore's total diet study on the prioritised chemical hazards of interest for a more precise assessment of the distribution of risk in the population. Direct measurement of chemicals and/or metabolites in biological specimens obtained from study subjects will be conducted to provide a more comprehensive understanding on the baseline dietary chemical exposure in the local population. Dietary assessment using food frequency questionnaire will be administered to the same group of study subjects to associate human exposure to chemical hazards with food consumption across the different population groups in Singapore.

Interventions

OTHERFood Frequency, Social, Lifestyle, Demographic Questionnaires and Blood Collection

Questionnaires on food frequency, social, lifestyle, and demographics will be administered to participants and will be correlated with the presence of chemical hazards in the blood. The chemical hazards analyzed will be referenced from Singapore's Total Diet Study, based on the prioritized chemical hazards of interest to investigate the distribution of risk in the population.
