“…The proposed occupational exposure limit (OEL) for spores is 1-10 5 spores/m 3 and values of TFC in this study fell within the limit. Sawane and Sawane [28] reported a mean of 72.26 x 10 3 CFU/m 3 for bacteria 65.91 x 10 3 CFU/m 3 for fungi in their work, which is close in range with this study. Tobin et al [15] reported TVC and TFC > 4162.99 CFU/m 3 .…”

This study aimed to assess air pollution and health hazards around selected sawmills within Port Harcourt metropolis. The physicochemical parameters of the air at the sawmilling sites were determined using onsite air quality analysers. The microbiological parameters were determined using the settling plate technique and the isolates identified based on their cultural and biochemical characteristics. Results showed that estimates of the monitored physicochemical parameters varied with prevalent human activity, time of exposure and atmospheric conditions. At Rumosi, SO2, VOCs and TSP with a concentration 1.250 ppm, 550.500 ppm, 323.200 µg/m3 respectively exceeded the Federal Ministry of Environment (FMEv) & World Health Organization (WHO) limit irrespective of the atmospheric condition, time and day of sampling, while the temperature, PM2.5, PM10 and NO2 with a concentration of 39.450oC, 209 µg/m3, 348.350 µg/m3, 0.181ppm respectively varied and was within the FMEv acceptable standard. At SARS Road Sawmill 1, VOCs, PM10 and TSP exceeded the FMEv limit while at SARS Road Sawmill 2, SO2, NO2, VOCs, PM10 and TSP exceeded the FMEv limits. Microbiological analysis revealed that the bioaerosols contained 12 bacterial genera (Aeromonas, Citrobacter, Staphylococcus, Micrococcus, Klebsiella, Serratia, Pseudomonas, Proteus, Providencia, Shigella, Enterobacter and Bacillus) and 7 fungal genera (Penicillium, Fusarium, Geotrichium, Cladosporium, Rhizopus and Trichophyton and Aspergillus) with total heterotrophic bacterial count (THBC) and total fungal count (TFC) ranging from 2711-26980 CFU/m3 and 373-12851 CFU/m3 respectively. The study also showed that sawmills within Port Harcourt do not pay much attention to the provision and use of Personal Protective Equipment (PPE), as they were generally not provided. The sawmill workers commonly reported cough and chest pain which they admitted could be associated with their jobs. This study has shown that air around sawmill sites contains inhalable chemical and biological agents which could cause respiratory problems to workers with prolonged exposure and dose response. Sawmill operators should provide and enforce the use of PPE within their facility. It is recommended that sawmill workers and other visitors wear personal protective gadgets in the processing area of the sawmill factories. Further study to relate workers symptoms with emission is recommended.

There is an increasingly high suspicion of occupational health diseases amongst workers in sawmill factories. Hence this study aimed to determine the microbial diversity in some sawmill factories in Okada, Edo State, Nigeria to evaluate potential implications of the factory’s processing area on the health of the workers and wood merchants. Bacteria and fungi count in the bioaerosols within the processing area of each factory was performed with the passive air sampling technique. While in the sawdust samples, microbial counts were carried out with the pour plate technique. Identification of the microbes was performed with macroscopic and microscopic examinations as well as standard phenotypic tests. Mean total viable count (TVC) and total fungi count (TFC) of bioaerosols in the air within the processing area of the sawmill factories were found to be greater than 4162.99 CFU/m3 while mean total coliform count (TCC) was reported as 756.28 CFU/m3. Fisher (F) one-way ANOVA test of the TVC and TCC dataset of bioaerosols from the four sawmill factories indicated no significant difference (p = 0.77 and 0.83 for TVC and TFC respectively) in the mean TVC and TFC of the bioaerosols. Bacterial (Micrococcus, Staphylococcus, Bacillus, Klebsiella and Serratia) and fungal (Saccharomyces, Aspergillus, Cladosporium and Penicillium) species were isolated from the bioaerosols and sawdust samples. Results of this study indicated that workers in the sawmill factories and other wood merchants who visit sawmill processing area are most likely exposed to airborne contaminants that may cause occupational diseases such as ophthalmic irritations and dermatitis. Hence it is recommended that sawmill workers and other visitors wear personal protective gadgets in the processing area of the sawmill factories.
