Keywords:
Contamination of air, Fungi, Waste disposal facilityAbstract
This cross-sectional research aimed to study species and quantity of airborne fungal in the ambient air at the municipal waste disposal facility in Bueng Kok Sub District, Bang Rakam District, Phitsanulok. The study areas were selected using the purposive sampling method. The open plate technique was used to collect samples for 8 hours in all 6 points around the landfill area, the north, the south, the east, the west, the center of the waste treatment area, and the point between sorting garbage area and the resting area of the workers. A total of 20 samples were evaluated and compared with the recommended levels of bacteria and fungi of The American Conference of Governmental Industrial Hygienists (ACGIH).
The results showed that the highest amounts of fungal found at the center of the waste treatment area (1,812.5 CFU/m3), followed by the east (1,375 CFU/m3), the north (802.5 CFU/m3), the south (500 CFU/m3), the west (375 CFU/m3), and the point between sorting garbage area and the resting area of the workers (62.5 CFU/m3), respectively. In total, five fugal were found and identified as Aspergillus Niger (39.0%), Aspergillus Fumigatus (33.3%), Aspergillus Flavus (11.1%), Fusarium spp. (11.1%) and Acremonium spp. (5.6%).
