Abstract
Assessment of seasonal variation in concentration of the heavy metals-
Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn- in Abattoir dump site soil at Yauri,
Nigeria, was undertaking during the two major seasons of Nigeria. This
was done to determine the environmental pollution status of the soil at
the dump site. Soil samples (0\u201315cm) collected during the
2007/2008 rainy and dry seasons were treated and digested using
microwave acid digestion methods. The heavy metal concentrations were
determined with Atomic Absorption spectrophotometer (AAS). The mean
levels range of Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were 13.2 -
30.02mg/kg, 59.14\u2013102.50mg/kg, 59.32 \u2013 96.13mg/kg, 2569
\u2013 4130mgkg, 263.01 \u2013 608.11mg/Kg, 36.21 \u2013107.13mg/kg,
15.60 \u2013 30.09mg/kg and56.31\u2013 92.50mg/kg for dry seasons and
10.13\u201322.76mg/kg,49.96\u2013
89.46mg/kg,49.12\u201373.08mg/kg,23330.02\u2013

561.03mg/kg,33.50\u201399.06mg/kg,16.20\u201328.11mg/kg, and 50.91-
89.10mg/kg for wet season respectively. The analytical results
indicated that in both wet and dry seasons some metals concentrations
were above the literature levels of a typical soil, which course for
concern. @ JASE
