Title Monitoring risks in association with exposure levels among wastewater treatment plant workers
Bibliographic information Nov. 2007, Vol.49, No.11, p.1235-1248. Illus. 57 ref.
Abstract The objective of this study was to investigate the relationship between exposure to hydrogen sulfide and endotoxins, and health symptoms among wastewater treatment plant (WWTP) workers. The exposure levels for specific tasks were measured by personal monitoring. Data on health symptoms were collected by means of questionnaires. Higher risks of respiratory, ocular and skin irritation, neurological and gastrointestinal symptoms were found among WWTP workers compared with unexposed workers. Tasks related to sludge handling and plant inspection showed statistically significant associations with memory and concentration difficulties, throat irritation and stomach pain.
