AI Article Synopsis
- The study focused on evaluating clinical symptoms in electroplating workers exposed to cyanide, comparing responses from silver-plating and gold-plating workers.
- Results indicated that silver-plating workers experienced higher levels of cyanide exposure and reported more health symptoms, such as nasal bleeding and skin scalding.
- Urinary thiocyanates emerged as a potential biomarker for measuring cyanide exposure, linked to the level of exposure at the workers' respective plants.
Article Abstract
Objective: This study aimed to investigate clinical symptoms among electroplating workers exposed to cyanide.
Methods: In this study, 26 silver-plating and 51 gold-plating workers completed questionnaires and were tested for urinary thiocyanates. Air cyanide, urinary thiocyanates, and clinical symptoms were compared between workers using Student t and χ 2 test and further analyzed by multivariate linear regression.
Results: Air cyanide and urinary thiocyanate were higher in the silver-plating plant than the gold-plating plant. In both plants, a dose-response relationship was observed between exposure status and thiocyanate levels. Silver-plating workers reported a higher frequency of almond odor detection, nasal bleeding, excessive salivation, skin scalding, and corrosion. Urinary thiocyanates were associated with the plant and exposure status, but not with smoking.
Conclusions: Our study suggests that silver-plating workers had higher exposure and more symptoms. Urinary thiocyanate may be a useful biomarker for cyanide exposure.
