Seasonal Variation in Mycological Quality of Air Environment Around a Major Market Along East-West Road in Bayelsa State, Nigeria

The distribution of bio-aerosols in diverse environments is a major concern to aero-microbiologists and environmentalists general. study evaluated the mycological quality air environment around market along East-West road Bayelsa State, Nigeria. Petri dish containing sterile Potatoes dextrose agar was exposed for 10 minutes state at height 1 meter. density diversity isolates were determined following standard procedures. fungi–aerosols ranged from 0.0073 - 0.0268 CFU/min-m2 statistical higher dry (November, January March) compared wet (May, July September) seasons, an indication seasonal influence. A total 11 fungi species recorded with 5 predominant viz Aspergillus fumigatus, flavus, niger, Fusarium chlamydosporum Penicillium (occurring ≥66.67% months), while 6 species, lentulus, nidulans, terreus, Cladosporium cladosporioides, Microsporum canis Mucor are opportunistic occurring ≤50% months). Most found soil, known produce toxins cause diseases. There need concerted effort by local government authorities via its agencies sensitize people on proper hygiene practices markets.
