Determination Of Physicochemical And Heavy Metal Content Of Soil Around Paint Industries In Kaduna

Abstract the increasing trend of environmental contamination by heavy metals is an issue of concern. The need for a continual monitoring of heavy metal content of soil around industrial areas becomes pertinent. The present study focuses on the physicochemical properties and heavy metal content of soil around vicinities of paint industries in Kaduna. The range of pH EC and TOM obtained were 6.500.20 to 8.030.20 22520.1 to 52014.0Scm and 2.180.01 to 3.100.01 respectively. The percentage of sand was 61 to 89 while silt and clay were 12 to 29 and 0 to 10 respectively. The mean concentrations of the heavy metals were Pb 30.800.15 to 79.600.87 gg Zn 128.352.16 to 273.000.92 gg Cu 15.450.39 to 27.000.0.13 gg Mn 102.91.47 to 237.20.75 gg Cd ND to 1.300.20 gg Cr 28.500.36 to 51.500.30 gg and Fe 1084.433.58 to 6542.322.56 gg. The metal content of the samples were generally higher when compared to those of the control which indicates contaminations mainly due anthropogenic contributions. The result of geoaccumulation index and enrichment factor also revealed moderate contamination in most of the samples. There was also a significant positive correlation p0.05 among some of the metals investigated.
