ABSTRACT
The bacterial and physicochemical properties of hair salon wastewater and contaminated soil in Benin metropolis were investigated. Investigations were carried out on five hair salons from different locations in Benin City. The mean physicochemical analysis showed that the samples had high chemical oxygen demand of 208.00 mg/l, and a low highest biological oxygen demand of 2.7 mg/l with a constant temperature of 22.2°C for all samples. It was observed that the wastewater samples from the three different locations were highly contaminated as the mean bacterial count of 2.50 ± 1.41 x 105 to 14.3 x ± 0.42 x 105 Cfu/ml. The Mean fungi count for for the saloon wastewater samples ranged from 3.6 ± 0.00 x 105 to 10.0 x ± 2.80 x 105 Cfu/ml. five (5) different bacterial organisms were isolated from hair dressing salon waste water samples in Benin metropolis. The organisms were revealed from the morphological parameters and biochemical tests conducted for their identification. They include: Staphylococcus aureus, Pseudomonas sp., Streptococcus spp., Escherichia coli and Bacillus sp. with S. aureus occurring most. The fungi isolates were, Rhizopus sp., Mucor sp. Aspergillus sp. Mechanisms for proper treatment and disposal of salon waste-water should be developed for commercial hair dressers so that the waste-water from such commercial ventures are treated and properly disposed. Isolation of pathogens from salon wastewater indicates that the hygiene standards employed are not adequate. This calls for agencies in the public health sector to sensitize and organize lectures, training workshops and seminars for the operators and workers of hairdressing and beauty salons in the communities.
