dc.description.abstract | To provide necessary information for future environmental monitoring of smelting and litharge making industries in Korea,environmental monitoring dataset of air lead concentration of 4lead industries(1 primary smelting, 2 secondary smelting and 1litharge making industry) were analyzed from 1994 to 2007. Data were compared using geometric mean and standard deviation with minimum and maximum values according to year of measurement, type of lead industries and type of operation of lead industries. The geometric mean and standard deviation of air concentration for a total of 1140 samples in all lead industries for overall 14 years were 70.7㎍/㎥ and 5.51 with minimum of 1㎍/㎥ and maximum of 9,185 ㎍/㎥. The overall geometric means of air concentration were above the permissible exposure levels(PEL) until year of 2001 and thereafter they were remained at the level of half of PEL. The geometric means of primary smelting, secondary smelting and litharge making industry for overall 14 years were 21.7㎍/㎥(number of samples: 353), 82.5㎍/㎥(number of samples: 357) and 164.2 ㎍/㎥(number of samples: 430)respectively. In primary smelting industry, the highest geometric mean air concentration was 35.4 ㎍/㎥in the secondary smelting operation; followed by casting operation (24.9 ㎍/㎥)and melting operation (14.9 ㎍/㎥), respectively. On the other hand, in secondary smelting industries, the highest geometric mean air concentration was 125.4㎍/㎥ in melting operation;followed by casting operation (90.5㎍/㎥) and pre-treatment operation (43.4㎍/㎥), respectively. However, in litharge making industries, there were no significant differences of geometric mean air concentrations between litharge operation and stabilizer operation. The proportion of over PEL (50㎍/㎥) was highest in litharge industry and followed by secondary smelting industries. However The proportions of over PEL(50㎍./㎥.) were decreased by the years of environmental monitoring. The significant reduction of mean air lead concentration since year of 2000 was observed due to more active environmental engineering control and new introduction of new operation in manufacturing process, but may be also influenced by non-engineering method such as reduction of operation hours or reduction of exposure time during actual environmental measurement by industrial hygienist according to more strict enforcement of occupational and safety law by the government. | - |
