In domestic agricultural products, heavy metals are one of the most important harmful substances together with residual pesticides. The purpose of this study was to investigate the contamination status of 17 agricultural products produced, distributed and sold in Jeonbuk Province in 2016 by investigating the contents of four heavy metals (Pb, Cd, As, Inogarnic As). Agricultural products were analyzed for 248 crops and 17 vegetables. For agricultur80al products, 17 items of cereals and vegetables were analyzed by 248 cases. Microwave method was used for preprocessing and ICP-MS was used. Heavy metals were detected in all samples. In the case of plumbumb(Pb), the mean detectable value was 0.032 for dried bracken, 0.094 for spinach, 0.050 for chestnut sweet potato, 0.023 for soybeans, 0.002 for green chilli, and 0.394 mg/kg for brown rice. Cadmium(Cd) was found to be 0.035 for dried bracken, 0.058 for spinach, 0.041 for potato, 0.024 for red pepper, 0.015 for chinese chive, 0.057 for nonglutinous rice, 0.022 in medicinal plant, 0.077 in brown rice and 0.071 mg/kg in chestnut sweet potato. As for arsenic, nonglutinous rice was 0.041, glutinous rice 0.047, brown rice 0.069, brown rice glutinous rice 0.067 mg/kg. In the case of inorganic arsenic was of 0.033 for nonglutinous rice, 0.070 for brown rice, 0.067 for brown glutinous rice, 0.039 for glutinous rice and 0.090 mg/kg for germinated brown rice showed the results. The samples that exceeded the residual limit of heavy metals (Cd 0.1, Pb 0.2 mg/kg) were 3 brown rice, 0.674 cadmium, 0.337 lead and 0.394 mg/kg lead. All 248 cases were analyzed for harmful heavy metals. Therefore, continuous safety management is required.
