Study on Comparison of the Amount of Trace Metals in Edible Viscera

시판한우 부산물 중 미량금속 함량의 비교조사

This study investigated the contamination of trace metals on edible visceras : tongue, intestine, lung, testis, gira, blood, liver, stomach, and kidney. The edible visceras were selected at random from ten markets in Seoul. The edible visceras underwent freeze drying prior to analysis. The contents of arsenic, cadmium, cobalt, chromium, copper, magnases, molybdenum, lead, and zinc were detected by ICP(Inductively Coupled Plasma Spectrophotometry). The results showed that the levels of trace metals in all the samples fall within the tolerance limit and cadmium in lung tended to be high(>0.1 ppm). Therefore, we may study and investigate continuously on the food contamination of heavy metals for the public health.
