Kim JH, Kim EA, Koh DH, Byun K, Ryu HW, Lee SG - Ann Occup Environ Med (2014)

Bottom Line: The proportion of the results ≥30 μg/dL decreased from 4.3% in 2003 to 0.8% in 2011.The blood lead levels in Korean lead workers decreased from 2003 to 2011 and were similar to those in the US and UK.Moreover, workers in industries conventionally considered to have a high risk of lead exposure also tended to have relatively high blood lead levels compared to those in other industries.

ABSTRACT

Objectives: This study aimed to document the trend in blood lead levels in Korean lead workers from 2003 until 2011 and blood lead levels within each of the main industries.

Methods: Nine years (2003-2011) of blood lead level data measured during a special health examination of Korean lead workers and collected by the Korea Occupational Safety and Health Agency were analyzed. Blood lead levels were determined by year, and a geometric mean (GM) was calculated for each industry division.

Results: The overall GM blood lead level for all years combined (n = 365,331) was 4.35 μg/dL. The GM blood lead level decreased from 5.89 μg/dL in 2003 to 3.53 μg/dL in 2011. The proportion of the results ≥30 μg/dL decreased from 4.3% in 2003 to 0.8% in 2011. In the "Manufacture of Electrical Equipment" division, the GM blood lead level was 7.80 μg/dL, which was the highest among the industry divisions. The GM blood lead levels were 7.35 μg/dL and 6.77 μg/dL in the "Manufacturers of Rubber and Plastic Products" and the "Manufacture of Basic Metal Products" division, respectively.

Conclusions: The blood lead levels in Korean lead workers decreased from 2003 to 2011 and were similar to those in the US and UK. Moreover, workers in industries conventionally considered to have a high risk of lead exposure also tended to have relatively high blood lead levels compared to those in other industries.

Figure 1: Median blood lead levels of Korean lead workers from 2003 to 2011. The values are reported as the 25th, 50th, and 75th percentiles for each year.

Mentions: There was a decreasing trend in the GM (2003, 5.89 μg/dL; 2011, 3.53 μg/dL; Table 2) and median (2003, 5.50 μg/dL; 2011, 3.38 μg/dL; Figure 1) blood lead levels over time. The total number of measurements (2003, 31,137; 2011, 49,772) and the mean age increased over time. The proportion of male workers was considerably higher than that of female workers, and the proportion of male workers increased over time (2003, 75.2%; 2011, 88.6%).
