The study examined the heavy metal components, physical and chemical parameters of soil samples around selected industrial establishments. This was to ascertain the level that industrial activities impacts on the soil quality with a view to providing a platform for rapid generation of data for environment related decision making and promoting compliance to environmental standards in Ibadan metropolis. Twelve composite soil samples to the depths of 0-15 cm, 15-30 cm, 30-45 cm to represent top and subsoil were collected at each of the selected industrial locations using soil auger for soil physical and chemical properties determination. Data collected were analysed using descriptive and inferential statistics. The mean Pb values for 0-15, 15–30, 30-45 cm soil depths were 5.66± 0.55, 4.58±0.68, 4.52±1.35mg/kg; Cd values were 10.23± 0.60, 9.40 ± 1.33 and 10.55± 0.36mg/kg; Co values were 9.76± 1.00, 9.98 ± 2.57 and 13.58 ± 4.16mg/kg; Cr were 10.18 ± 2.40, 12.53 ±3.17 and 12.1 ± 3.75 and Ni were 11.17 ± 3.55, 12.24 ± 2.19 and 12.53 ± 2.34 mg/kg. For Macro nutrients, Total Organic Carbon (TOC) mean values for BC was 33.50 ± 2.48, 29.3 ± 3.91, 26.6 ± 2.74 and 3.60 ± 0.16 and TN values were 3.60 ± 0.16, 3.40 ± 0.12, and 2.90 ± 0.28 respectively while AC had Total Organic Carbon mean values of 28.03 ± 0.65, 23.5 ± 2.01, 19.24 ± 1.43 and Total Nitrogen (TN) mean values 2.90 ± 0.07, 2.43 ± 0.21 and 1.99 ± 0.15 respectively. For Micro nutrient Mn, Fe, Cu, Zn, the mean values at 0-15, 15-30 and 30-45 soil depth for BC were 39.08 ± 9.57, 32.43 ± 11.93 and 18.78 ± 4.80 for Mn, mean values for Fe were 39.53 ± 15.58, 51.83 ± 14.62 and 34.33 ± 10.68, also mean values for Cu was 8.53 ± 0.32, 8.26± 0.29, 7.99 ± 0.06 and mean values for Zn were 9.01 ± 0.66, 6.62 ±0.21 and 4.42 ± 1.11 respectively. There was a decrease in value with depth which may be associated with downward movement of organic materials and nutrients. The study concluded that industrial activities are impacting on the soil quality with special reference to nutrient and heavy metal contents within and around industrial facilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
