Environmental Pollution Survey of Xenobiotics in Soil, Plant and Water Around a Steel Rolling Mill in Nigeria
Physicochemical characteristics of soil, water and plant collected during dry and rainy seasons from a steel rolling mill industry along Ile-Ife road in Osun State were determined using standard methods. Soil analysis revealed highest level of pH to be 8.04, conductivity-0.15 µS/cm, lead-394 ppm, nickel-54.0 ppm, copper-296 ppm, chromium-123 ppm, zinc-975 ppm, iron-85060 ppm, Total organic matter-2.27 ppm, moisture content-38.0%, total organic carbon-1.28 ppm, oil and grease-6.00 ppm. Plant analysis showed highest concentration of pH to be 6.4, conductivity-3.20 µS/cm, highest metal content to be iron-4237 ppm. Water analyzed showed highest concentration of iron to be 457 ppm, zinc-32.6 ppm, chloride-213 ppm, calcium-24.1 ppm, sulphate-55.0 ppm, colour- 406, calcium hardness-60.0 ppm, turbidity-316 NTU, phosphate-11200 ppm, temperature-23.3°C, magnesium hardness-150 ppm, conductivity-1210 µS/cm, total suspended solid-725 ppm, oil and grease-20 ppm, acidity-50.0 ppm, alkalinity-0.50%, 286 ppm, salinity-0.50%, sulphite-180 ppm and total dissolved solid-605 ppm. Study revealed soil to be polluted with heavy metals compared to water and plant samples collected. Parameters in water such as turbidity, phosphate, total dissolved solids, zinc and copper exceeded the maximum permissible level of the World Health Organization, an indication that the water here may not be usable for drinking and some other categories of water usage. Statistical significant differences were observed between means of parameters analyzed in study area. It is therefore important to continuously monitor the environment because of the dangers it will pose on human, animals and plants.
