ABSTRACT
Paint manufacturing has grown in recent years in response to the increasing demand for high quality paints. Consequently, large amount of wastes are released into the environment. This study investigated the assessment of the impact of paint waste on the fungal profile of the soil. The paint effluent increased the heavy metals (lead and cadmium) in the soil. These effects were significant (Lead – 2.212 ± 002mg/kg) and cadmium (1.875 ± 0.008mg/kg) compared to the control (Lead – 2.212 ± 002mg/kg) and (cadmium 1.875 ± 0.008mg/kg). The total fungal count of the soil simple was (30). A total of 4 fungal isolate was characterized macroscopically and microscopically and the zone of inhibition was measured for each isolate impacted with the paint waste. (Penicillium sp. – sensitive), (Aspergillus sp – sensitive), (Cladosporium sp. – Resistant) and (Rhizopus sp. – Resistant), Aspergillus sp and Cladosporium sp. were sensitive to paint waste while Cladosporium sp. and Rhizopus sp. were resistant, sine the paint effluent does not favor all the fungal organisms in the soil remediation and adequate treatment of the waste should be carried out as to protect the soil health.
