The Contents of Heavy Metal in Air of Factories and Blood, Urine and Hair at Employees of I-ri Industrial Park Area
초록
In Iri industrial area, Heavy metals in ait of the factories, 10 metal and 8 non-metal factories, were examined for ten months(from Feb. to Nov, 1991). The methals in blood, urin and hair of 232 employees who have worked in the factories were also examined at the same time The results are summarized as follows 1. Heavy metals Pb, Cd and Mn in the metal factories were 0.031mg/m$^{3}$, 0.0065mg/m$^{3}$, and 0. 035mg/m$^{3}$ respectively, but 0.017mg/m$^{3}$, 0.021mg/m$^{3}$ and 0.014mg/m$^{3}$ in non-metal factories. 2. Heavy metals such as Pb, Cd and Mn in blood from employees in the metal factories were measured : 22.36$\mu$g/dl, 0.27$\mu$g/dl and 1.26$\mu$g/dl respectively, The values in the non-metal factories were 19.84$\mu$g/dl, 0.21$\mu$g/dl and 1.24$\mu$g/dl. 3. Heavy metals such as Pb, Cd and Mn in urine from employees in the metal factories were measured 32.94$\mu$g/l, 0.16$\mu$g/dl, and 1.60$\mu$g/dl respectively, whereas the values in the non-metal factories were 28.79$\mu$g/l, 0.13$\mu$g/dl and 1.35$\mu$g/l. 4. Heavy metals such as Pb, Cd and Mn in hair from employees in the metal factories were measured 8.92mg/kg, 0.33mg/kg and 3.71mg/kg respectively, but 8.14mg/kg, 0.31mg/kg and 3.26 rng/kg in the non-metal factories.
