Geochemical Assessment of Industrial Activities on the Quality of Sediments and Soils Within the Lsdpc Industrial Estate, Odogunyan, Lagos, Nigeria

This study examined the impact of industrial activities within the LSDPC Industrial estate in Odogunyan, on the quality of the sediments and soils within the area. Twenty samples comprising drainage sediments and soils were obtained from within the drains and surrounding areas of the industrial estate. These samples were dried and disaggregated and sieved to appropriate sizes for geochemical analysis. The samples were subsequently digested and analyzed using ICP-OES at the Activation Laboratories, Ontario Canada. The results of the geochemical analysis showed the following range of concentration for some selected metals Cd (0.20-2.10ppm), Cu (28.00-153.00ppm), Pb (20.00-148.00ppm), Zn (61.00-1133.00ppm), Mn (189.00-2024.00ppm), Mo (bdl-6.00ppm) and W (bdl-6.00ppm). Geochemical evaluation of the results obtained from the analysis to ascertain their environmental implications indicated that these selected metals are the principal pollutants found in the study area and that the level of these metals in the soils and sediments around these industrial estate can be linked to the industrial practices of the manufacturing outfits located in the area who dump their untreated wastes into the environment without any treatment.
