“…Rainfall aid in the distribution of microbial particles from higher elevations to ground-level environments, while cloud acts as a cover to prevent the penetration of ultraviolet irradiation, which inactivates culturable microorganisms (Kang et al, 2015). However, this study is at variance with the reports of studies that opined that increased temperature and relative humidity of the e n v i r o n m e n t f a v o u r t h e g r o w t h o f microorganisms (Ren et al, 2001;Ambrose et al, 2015).…”

“…Several studies have reported species of the genus Proteus and Enterobacter in the air. These bacterial isolates have been associated with indoor and outdoor environments in previous studies (Wemedo et al, 2012;Ambrose et al, 2015;Al-Mayahi, 2017;Agwaranze et al, 2020). Proteus mirabilis is part of the normal flora of the human gastrointestinal tract.…”

Exposure to bioaerosols poses significant health risks to occupants of buildings, especially in tropical areas due to its climatic characteristics that favour airborne bacterial growth. This study investigated the levels and composition of indoor and outdoor airborne bacteria in residential buildings in Benin Metropolis. Air samples were collected from forty-five randomly selected houses across the five local government areas in Benin City using the passive sampling technique. The culture-dependent 16S rRNA gene technique was utilized in theidentification of the bacterial isolates. The results revealed that the mean concentrations of the indoor and 3 3 outdoor total bacteria varied from 476.1 to 939.3 CFU/m3 and 181.1 to 373.2 CFU/m3 in the wet season, 335.0 3 3 to 457.2 CFU/m3 and 387.2 to 627.8 CFU/m3 in the dry season, respectively. The concentration of indoor and outdoor airborne bacteria varied significantly (P=0.001) during the wet and dry seasons. Basic Local Alignment Search Tool homology showed that the 16S rRNA gene sequences of isolates were related to Proteus mirabilis, Pectobacterium brasiliense, and Enterobacter sichuanensis. The bacterial communities identified are associated with humans and other outdoor environmental media and could lead to critical health outcomes among exposed vulnerable occupants of the buildings. This study, therefore, provides a database for airborne bacteria in residential houses in the study area and could assist in the implementation of effective interventions that reduce the risks and provide a safe environment.

This study was conducted to assess the outdoor air quality of some urban slums in Port Harcourt. Six sampling sites were selected, from the Port Harcourt urban slums; two sites from each slum represented with a suffix 1 or 2. The slums are designated Marine base (#1 and #2), RSU BG, Obudu 2, Bundu (#1 and #2). The air quality was analyzed using portable handheld air quality analyzer and the microbiological parameters were determined by standard cultural method. The study revealed that the sampled sites were laden with bacterial and fungal species. namely; Klebsiella sp., Micrococcus sp., Escherichia sp., Pseudomonas sp., Baccilus sp., Aeromonas sp., Streptococus sp., Serratia sp., Aerococcus sp., Proteus sp. Penicillium sp., Fusarium sp., Candida sp., Aspergillus sp., Mucor sp., Rhizopus sp. and Tricorderma sp. Highest obtained noise level was at Marine base 1 which was 66 db, highest relative humidity of 54.8% at RSU BG, CO2 (ppm) values of 4.8, 80, 796, 850, 638, 698 for Marine base 2, Marine base 1, Obudu 2, RSU BG, Bundu 1 and Bundu 2 respectively. The values for NO2 (ppm) was (0.05, 0.053, 0.071, 0.022, 0.035, 0.023), suspended particulate matter (ppm) was (7.1, 8.7, 9.5, 9.5, 6.2, 6.2), SO2 (ppm) was (0.42, 0.15, 0.50, 0.34, 1.26, 0.41) CO (ppm) was (4.8, 1.7, 2.2, 3.0, 3.9, 3.6) and volatile organic compound (ppm) was (1.0, 1.1, 0.9, 75 and 1.2). This study has shown that Port Harcourt urban slums are experiencing some degree of contamination not acceptable for healthy living that requires attention to curb. These areas require all-round improvement in sanitation. M Give one sentence on methodology.
