Indoor bioaerosol

Bioaerosol na cikin gida shi ne tarin ƙananan barbashi na asalin halittu da ke shawagi a cikin iska na cikin gida. Waɗannan barbashi na iya kasancewa na halitta ko kuma na wucin gadi, kuma asalin su na iya fitowa daga ƙwayoyin cuta, tsirrai ko dabbobi. Ana kuma kiran su da ƙurar halitta.
Bioaerosols na iya ƙunsar ƙwayoyin cuta, fungi (ciki har da spores da guntattun sassa na fungi), ƙwayoyin birus, gubobi da kwayoyin cuta ke samarwa, pollen, da filayen tsirrai.
