Plasma levels of unintentionally produced non-Aroclor polychlorinated biphenyl (PCB) congeners in workers from the silicone rubber industry
The unintentional release of non-Aroclor-PCBs 47, PCB 68 and PCB 51 by a silicone manufacturing company in North Rhine-Westphalia, Germany, due to the use of bis-(2,4-dichlorobenzoyl)peroxide (2,4-DCBP) as an initiator has raised serious concerns about the possible uptake of these congeners by worke...

520 | |a The unintentional release of non-Aroclor-PCBs 47, PCB 68 and PCB 51 by a silicone manufacturing company in North Rhine-Westphalia, Germany, due to the use of bis-(2,4-dichlorobenzoyl)peroxide (2,4-DCBP) as an initiator has raised serious concerns about the possible uptake of these congeners by workers in silicone rubber production. We have conducted a pilot study in Germany to quantify these congeners in plasma samples of employees working in and handling silicone rubber during production and electrical cable manufacturing. A total of 117 plasma samples were collected from workers in 7 companies and 84 plasma samples from control subjects not working in silicone industry. PCB 47 and PCB 68 were detected in plasma above the limit of quantification (0.01 μg/L) in 84% and 66% of the silicone industry workers, respectively, whereas both congeners were undetectable in plasma of the control group. The maximum levels for PCB 47 were 2.56 μg/L and for PCB 68 were 0.42 μg/L. PCB 51 could not be determined in any plasma sample. Plasma samples of workers making electric cables had in general lower levels than those from workers making silicone rubber. Due to the high persistence of PCBs and the poorly defined toxicological properties of PCB 47 and PCB 68, a replacement of 2,4-DCBP as initiator in silicone rubber production should be considered. Given the large market for silicone products, our results might have a global impact on silicone industry. | ||

We have conducted a pilot study in Germany to quantify these congeners in plasma samples of employees working in and handling silicone rubber during production and electrical cable manufacturing. A total of 117 plasma samples were collected from workers in 7 companies and 84 plasma samples from control subjects not working in silicone industry. PCB 47 and PCB 68 were detected in plasma above the limit of quantification (0.01 μg/L) in 84% and 66% of the silicone industry workers, respectively, whereas both congeners were undetectable in plasma of the control group. The maximum levels for PCB 47 were 2.56 μg/L and for PCB 68 were 0.42 μg/L. PCB 51 could not be determined in any plasma sample. Plasma samples of workers making electric cables had in general lower levels than those from workers making silicone rubber. Due to the high persistence of PCBs and the poorly defined toxicological properties of PCB 47 and PCB 68, a replacement of 2,4-DCBP as initiator in silicone rubber production should be considered. Given the large market for silicone products, our results might have a global impact on silicone industry.

Plasma levels of unintentionally produced non-Aroclor polychlorinated biphenyl (PCB) congeners in workers from the silicone rubber industry |
abstract |
The unintentional release of non-Aroclor-PCBs 47, PCB 68 and PCB 51 by a silicone manufacturing company in North Rhine-Westphalia, Germany, due to the use of bis-(2,4-dichlorobenzoyl)peroxide (2,4-DCBP) as an initiator has raised serious concerns about the possible uptake of these congeners by workers in silicone rubber production. We have conducted a pilot study in Germany to quantify these congeners in plasma samples of employees working in and handling silicone rubber during production and electrical cable manufacturing. A total of 117 plasma samples were collected from workers in 7 companies and 84 plasma samples from control subjects not working in silicone industry. PCB 47 and PCB 68 were detected in plasma above the limit of quantification (0.01 μg/L) in 84% and 66% of the silicone industry workers, respectively, whereas both congeners were undetectable in plasma of the control group. The maximum levels for PCB 47 were 2.56 μg/L and for PCB 68 were 0.42 μg/L. PCB 51 could not be determined in any plasma sample. Plasma samples of workers making electric cables had in general lower levels than those from workers making silicone rubber. Due to the high persistence of PCBs and the poorly defined toxicological properties of PCB 47 and PCB 68, a replacement of 2,4-DCBP as initiator in silicone rubber production should be considered. Given the large market for silicone products, our results might have a global impact on silicone industry. |
