Objectives : This study is conducted to evaluate airborne lead concentration in and around lead production plant.
Methods : Airborne lead concentration was monitored simultaneously inside of the processes of lead recycling factory and outside of factory which include stack, boundary of factory and residential area 1 km and 7.5 km from factory, respectively. All samples were measured three times at 1.5 m from the ground and analyzed using inductively coupled plasma mass spectrometer, inductively coupled plasma optical emission spectrometer or flame atomic absorption spectrometer.
Results : All airborne lead concentrations measured inside of factory(13.9 ㎍/㎥-252.9 ㎍/㎥) and outside of factory(0.001 ㎍/㎥-54.97 ㎍/㎥) showed log-normal distribution. Geometric mean lead concentration, 54.81 ㎍/㎥, measured inside of factory was significantly higher than outside of factory, 0.20 ㎍/㎥(p<0.01). Among the samples measured inside the factory, lead concentration was the highest in the refining process(59.02 ㎍/㎥-252.9 ㎍/㎥). In the case of the samples outside the factory, the nearest chimney was the highest(3.84 ㎍/㎥-54.97 ㎍/㎥), and the lead concentration at the farthest place, 7.5 km from the factory was the lowest(0.001 ㎍/㎥-1.7 ㎍/㎥). The arithmetic lead concentration, 0.45 ㎍/㎥ in the residential area near the factory was below the atmospheric environment standard of 0.5 ㎍/㎥, but the maximum concentration of 3.4 ㎍/㎥ was exceeded.
Conclusions : Airborne lead concentration in residential area, 1 km away from lead recycling plant, may exceed ambient air standard of 0.5 ㎍/㎥.
