Abstract
This study reports on the concentrations of airborne fungi in a waste paper and cardboard recycling factory (WPCRF) in Tehran, Iran. Sampling occurred every six days during winter at nine locations. The following order was observed in all processing units: Penicillium sp. (92 ± 6 CFU m−3) > Cladosporium sp. (74 ± 7 CFU m−3) > Aspergillus niger (19 ± 9 CFU m−3). In the processing units, the lifetime average daily dose ranged from 1.49 × 10−3 to 7.8 CFU (kg.d)−1 for the inhalation route and from 2.74 × 10−6 to 6.29 × 10−6 CFU (kg.d)−1 for the dermal route.
