Desalination study of physicochemical properties from soils in mechanic workshops within Okitipupa, Ondo state, Nigeria.

Auto Mechanic Workshops in thestudy area generate waste containing hazardous chemicals Thirty-six Soil samples were collected from selected automobile workshops (five) in the study area at the depths of 0-15 cm, 30-45 cm, 45-60 cm, 60-75 cm and 75-100 cm. A total of sixty (30) soil samples were collected in five different locations in the ancient town of Okitipupa. Six control samples were also collected in a farm land about 3km away from Auto Mechanic Activities. The physicochemical parameters such as soil composition based on particle size in percentage, ranged 7.65-10.71 for clay, 1.93-6.99 for silt and 85.36-89.98 for sand pH values ranged 4.57-5.93 and electrical conductivity (EC) (?scm?1) ranged 31.67- 143.67. The percentage soil composition was in this order; Sand>Clay>Silt. Assessment of pH shows acidity increases down the depth of the profile and EC follows the same trend. Comparing the values with the control indicate the presence of soluble inorganic salts that is higher in the study area than control.
