The physiochemical assessment of abattoir waste in Abeokuta metropolis were investigated. Waste were collected from five different abattoirs located in Abeokuta municipal. These were from points P1 to P5, in order to assess contaminants in the Abattoir in both dry and wet season. The results obtained were compared with WHO standard set limits. The temperature range were performed outside and inside the waste with 28.0OC and 29.0OC respectively. The mean pH in dry and wet season had 5.47, 5.58 and electrical conductivity had 0.37 μScm-1 and 0.75μScm-1 dry and wet season. The values were slightly less than the WHO standard. Pb in dry and wet season were higher than 0.015 WHO standard. The mean values of the Fe at both dry and wet season were 3.52 and 3.80 far higher than 0.03 the value of WHO standard. This evidently showed there is pollution as well as contaminants from the abattoir sites. Of all acidic parameters, P042- had 111.00mg/L and 148.55mg/L dry and wet season respectively, which is far greater than the value of 5mg/L WHO standard, S042- and cl2- had 7.34mg/L, 97.14 mg/L, 130.0 mg/L, 148.27 mg/L, both seasons; respectively. These values are within the 230mg/L WHO standard. Thus, the abattoir activities within Abeokuta metropolis impact positively in the environment and good measures should be put in place to arrest the condition.
