Bioaerosol Assessment
Processes that rely on microbial activity to break down waste materials and treat organic waste streams can generate emissions of bioaerosol. Also referred to as biological aerosol or organic dust, they are airborne microorganisms such as bacteria, actinomycetes, fungi, pollen, moulds, or viruses.
While, typically invisible to the human eye bioaerosols can penetrate deeply into our respiratory systems and can cause a range of health problems including gastrointestinal illness, bronchitis, and cancer.
The Environment Agency (EA) requires a Bioaerosol Assessment for all relevant processes where there is a workplace or dwelling within 250 metres.
Bioaerosol Generating Processes
- Composting
- Anaerobic digestion
- Mechanical biological treatment, e.g., biofiltration
Bioaerosol Generating Processes
Consideration of bioaerosols is important for internal (workplace / employee) and ambient (outdoor / public) exposure. Using our expertise in bioaerosol measurement and assessment techniques we follow relevant standards and industry guidance in support of planning and Environmental Permit applications. This helps our clients to minimise exposure and protect people from consequent health problems.
- Ambient Bioaerosol Measurement
- Monitoring using Andersen Microbial Impactors, Partisol Filtration Samplers, and Institute of Occupational Medicine (IOM) Personal Filtration Samplers
- Site Specific Bioaerosol Risk Assessment (SSBRA)
- Written following EA Guidance on the evaluation of bioaerosol risk assessments for composting facilities
- Comprising:
- Hazard Identification
- Exposure Assessment
- Risk Estimation
- Risk Characterisation
- Bioaerosol Dispersion Modelling
- Bioaerosol Mitigation Analysis
