Abstract

A study of the type and quantity of microorganisms in the ambient air at 6 municipal landfill sites, in Khon Kaen, include 3 small size and 3 large size of landfill. Collect sample by Andersen Single Stage Impactor. The concentration of microorganisms in large municipal landfill site ranged from 406 to 618.13 CFU/m3 morning, and from 238.51-482.39 CFU/m3 evening. Small municipal landfill site ranged from 292.59 – 352.80 CFU/m3 morning, and from 254.41 – 343.91 CFU/m3 evening. January to showed microorganisms large municipal landfill ranged from 945.71 - 1,735.85 CFU/m3morning, and from 1,079.86 – 1,185.56 CFU/m3evening. Small municipal landfill on morning 1,244.40 – 1,545.88 CFU/m3 on evening 1,090.35 – 1,601.29 CFU/m3. Resulted to show species of microorganisms in 6 landfills were not different, 3 spices of bacteria were Bacillus spp., Coagulase-negative staphylococci, Enterobacter spp. and 4 spices of fungi were Aspergillus fumigatus, Aspergillus flavus, Mucor spp., and Chaetomium spp.
