Work related symptoms among sewage workers.
British Journal of Industrial Medicine
|August 1, 1983
Summary
Sewage workers experienced more skin and gastrointestinal issues, potentially due to airborne Gram-negative bacteria in sewage aerosols. Further research is needed to confirm the link between bacterial toxins and these health symptoms.
Area of Science:
- Environmental Health
- Occupational Medicine
- Microbiology
Background:
- Occupational exposure to sewage aerosols can pose health risks.
- Gram-negative bacteria are prevalent in sewage and can become airborne.
Purpose of the Study:
- To investigate the health effects of airborne sewage aerosols on workers.
- To identify potential causative agents and biomarkers of exposure.
Main Methods:
- Interviews with employees at sewage and drinking water plants.
- Measurement of airborne Gram-negative bacteria.
- Analysis of serum immunoglobulin, white blood cell counts, and urinary fibrinogen degradation products (FDP).
Main Results:
- Sewage workers reported higher rates of skin disorders and gastrointestinal symptoms.
- Elevated FDP in urine was observed in non-smoking sewage workers.
- Slightly higher IgM concentrations and some elevated transaminase levels were noted in sewage workers.
Conclusions:
- Airborne Gram-negative bacteria in sewage aerosols may contribute to observed health symptoms in workers.
- Fibrinogen degradation products (FDP) may serve as a biomarker for exposure.
- Further investigation into bacterial toxins as a cause of symptoms is warranted.
