Abstract
This study analyzed the contamination level of harmful heavy metals in 3820 types of food samples currently available in Korea in 2010. A total of 119 types of samples were collected including corns, vegetables, fruits, fishes, mollusks, shellfish, crustacean, seaweed, bean products, meats and eggs from major 7 cities. These samples were analyzed using ICP-MS after pre-treatment with Microwave-digestion system. Analysis results of Lead, Cadmium and Mercury were compared with the standard specifications of Korea Food Standards Codex. As a result, high level of Pb, Cd, Hg were detected in “cockle”, “dried-squid” and “shark-meat”. Acceptable intake for consumers was checked using PTWI. Such results will be utilized as data on the exposure of human body through foods. In addition, satisfactory results were obtained through purchase and analysis of NIST CRM (National Institute of Science Technology Certified Reference Material) to obtain reliability on analysis results.
