Microorganisms in the air are considered as bioaerosols which can cause adverse effect to human health especially in the confine area with less air ventilation. In this study, the microorganisms and particulate matter less than 10 µm were observed their relationship with the meteorological factors. The comparison between the rural and urban area was conducted to evaluate the density of the bioaerosols. The samples were collected the Laem Phak Bia Environmental Research and Development Project in Phetchaburi Province (rural) and the Aor Por Ror Building (urban). The results showed that the concentration of microorganisms in the air and the concentration of particulate matters smaller than 10 µm in rural area were higher than urban area. The concentration of microorganisms in the air was highest at 8:00 am., and decreased by altitude and the major size was found ranged from 2.1-3.3 µm. The concentration of microorganisms in the air was significantly related to the meteorological factors, such as temperature, relative humidity and wind speed. The most common found microorganisms were Aspergillus spp., Penicillum spp., Cladosporium spp. which can be harmful to health.
