Abstract

This study was performed to evaluate methods for determination of airbone mercury in industrial environments. Three methods, such as Hopcalite method, passive monitoring method and Jerome method were evaluated at two (2) fluorescent lamp manufacturing Plants in Korea during a period from May 24 to May 31, 1994 and the result are as follows: 1. The average were concentrations of airbone mercury were $26{\mu}g/m^3$ by Hopcalite method, $25{\mu}g/m^3$ by passive monitoring method, and $38{\mu}g/m^3$ by the Jerome method, respectively, which were below the permissible exposure limit of $50{\mu}g/m^3$ established by both the Korean Ministry of Labor and ACGIH. However, 12 out of 49 cases(24.4%) in plant A and 2 out of 31 cases(6.5%) in plant B were in excess of the standard. 2. The relationship between the results by Hopcalite method and the passive monitoring method was significant(r=0.892). 3. The variation among three results by eath of three methods were different by process. The highest variation was determined at quality control process("process b") which invoved in large variation of concentrations. 4. When short term high concentrations were produced, the Hopcalite method was more efficient then the passive method.
