Abstract: Fish and game meat contain different essential nutriments for a good health. However, it can also contain contaminants, such as mercury and lead, that pose a health risk. To guide the communities that base their diet on hunting or fishing, the main objective of the project is to develop a portable analytical platform that allows the monitoring of contamination by heavy metals of country food on the field. To this end, an analytical strategy for the dissolution of food flesh that can be deployed outside of the laboratory and used by non-scientists has been established. This strategy includes sampling, flesh dissolution, analyte separation and matrix exchange for the analysis in addition to fluorimetric detection and quantitation of the analytes. Since the quantification system for this platform is still under development, we therefore developed an ICP-MS/MS method to quantify lead and mercury in our food extracts. This method was developed to analyze arctic char, a fish consumed all year long in some northern communities and in which the contamination level can vary significantly. The analytical process from sampling to monoelemental analysis by ICP-MS/MS will be discussed in this document.
