Investigation of the contribution of bioaerosol loading to indoor PM pollution on university campus in Singapore

Indoor bioaerosol pollution may cause allergies and diseases and with people spending up to 90% of their time indoors, the indoor bioaerosol loading on a university campus was investigated to quantify indoor air pollution and develop mitigation strategies. Culture-based air sampling and optical part...
