||A health survey of workers in the pentachlorophenol section of a chemical manufacturing plant
||July 1993, Vol.24, No.1, p.81-92. Illus. 52 ref.
||During 1968 to 1985, 109 workers who had been engaged in the production of pentachlorophenol, using non-gamma isomers of hexachlorocyclohexane (BHC) as the raw material, were surveyed. Endemic chloracne among them had been noted since 1974. The prevalence of chloracne was 73.4% (80/109) in total and 95.2% (20/21) in a trichlorobenzene (TCB) tank area where dioxin (PCDD) and dibenzofuran (PCDF) levels were thousands of ppm. It seems that PCDDs and PCDFs have not previously been reported from thermal decomposition of BHC. Urinary porphyrins were significantly higher among exposed workers than among the controls but there was no significant difference between the workers with chloracne and those without. The conduction velocities of the median motor nerves were much slower among the workers in the TCB tank area where the highest PCDD contamination appeared. The mortality study cohort was relatively young. Based on the three deaths observed during the follow-up, no association could be drawn.
