Abstract:
Objective To understand the air pollution by microorganisms in the underground spaces. Methods 51 underground spaces were investigated, the impact and sedimentation sampling methods were employed and the total bacterial count, mycetes, streptococcus and anaerobes in air were determined. ELESA was used to detect aflatoxin B1 in aspergillus flavus isolated from air. Results The total bacterial count in the air in underground spaces accorded with the military health standard. In the semi-closed spaces,the mycetes counts were 5 950 cfu/m3 and 9 500 cfu/m3 in aisle and rooms respectively, significantly higher than those in control group (P
