Abstract:
Airborne fungal contaminants in composting facilities gain more and more importance in regard to health hazards for workers and an emission of spores and microbial metabolites in the environment. Possible health impacts of bioaerosols are widely discussed from both an allergological and a toxicological point of view. The present study investigates in detail the exposure to airborne fungal spores at working places in compost plants. These fungal spores are compared to the spectrum of microbial volatile metabolites with regard to the physiological properties of each fungal species. The results indicate, that the spectrum of microbial volatile organic compounds (MVOC) as well as the production of mycotoxins can be specific for certain species. In addition to the pathogenic and allergological relevance, the fungi may have different toxicological health impacts. However, an evaluation of health effects caused by the great variety of volatile organic compounds remains difficult, since information on their toxicological impact is lacking.
Insights
Airborne fungal spores and microbial volatile organic compounds (MVOCs) in compost plants pose health risks. Species-specific MVOCs and mycotoxins are identified, but their toxicological impact requires further study.
Area of Science:
- Environmental microbiology
- Occupational health
Context:
- Composting facilities generate airborne fungal contaminants.
- Bioaerosols from compost present potential health hazards to workers and the environment.
- Fungal spores and microbial metabolites are key components of bioaerosols.
Purpose:
- To investigate airborne fungal spore exposure in compost plant workplaces.
- To compare fungal spore spectra with microbial volatile metabolites.
- To analyze the physiological properties and species-specificity of fungal metabolites.
Summary:
- Airborne fungal spores and microbial volatile organic compounds (MVOCs) were studied in compost facilities.
- The study found that MVOC spectrum and mycotoxin production can be species-specific.
