A Study on the Content of Cu, Fe, Zn, Mn, Pb, Cd in Market Milk

In order to determine the content levels of trace metals in cow's milk, 79 market milk samples were collected from markets in major cities of Korea from July to August, 1985 and analyzed for content levels of Cu, Fe, Zn, Mn, Pb, Cd. The Results were as follows Cu, average 43.5 $\mu$g/l range 14 ~ 172.7 $\mu$g/l Fe, average 398.4 $\mu$g/l range 35 ~ 1,873 $\mu$g/l Zn, average 2.917 mg/l range 1.233 ~ 7.46 mg/l Mn, average 26.74 $\mu$g/l range 7.6 ~ 102 $\mu$g/l Pb, average 33.9 $\mu$g/l range N.D. ~ 105 $\mu$g/l Cd, average 1.73 $\mu$g/l range N.D. ~ 5.4 $\mu$g/l
