Bioaerosol emissions from composting sites present a relatively low health risk
Commercial composting facilities can produce plumes of organic material containing bacteria, fungi, microbial toxins and dust. Exposure in the workplace to high levels of bioaerosols is associated with an increased risk of respiratory symptoms and chronic respiratory illness.
COMEAP has not considered Bioaerosols but the Environment Agency and Health Protection agency (now Public Health England) have published information.Available evidence suggests that emissions from composting sites present a relatively low health risk. Most people are unaffected by contact with bioaerosols but exposure has occasionally been linked to respiratory problems, headaches, nausea and fatigue.
Communities further than 250m from a site are unlikely to be exposed to harmful levels of bioaerosols, although they may experience an odour which may travel much further.
