Abstract
Microbes and mineral constituents of oil producing areas of Ondo State vary from site to site. The highest of 240×105 cfu/ml was recorded in Ayetoro compared with Sabomi having a low count record of 7×103 cfu/ml. Mineral element ranges from the lowest of 1.15 ppm and 2.13 ppm in Seluwa and Gbawiyo to highest of 468.73 ppm and 474.85 ppm in Ayetoro and Seja for Ca; 0.24 and 3.52 pp1m in areas like Sabomi and Araromi to 256.03 ppm and 1185.34 ppm in Ayetoro and Bijimi for Mg; 0.01 in Sabomi and Ilepete, Ayetoro, Ubale, Obeiji, Gbawiyo, Araromi, Abetobo, Pepe and Seluwa to 0.23 in Awoye, Ayetoro and Orioke for Mn; 0.07 ppm in Ayetoro to 2.71 and 6.63 ppm in Gbawiyo and Orioke for Fe; 0.01 in Igbokoda Jetty and Awoye, Ilepete, Ayetoro, Ubale, Obeiji, Gbawiyo, to 0.78 ppm in Awoye and most stations studied for Lead (Pb). 0 values were recorded for PO4-P (ppm) in Ayetoro 1, Araromi, Bijimi and Sabomi to 0.49 ppm in Awoye respectively. Other metal constituents in water samples are from the lowest of 64 ppm and 70.06 ppm in Gbawiyo and Awoye to highest of 440 and 400 ppm in Araromi and Obeiji for Cl; 0.1 ppm in Awoye, Ilepete, Ayetoro, Araromi and Pepe 3 to 1.0 and 0.9 ppm in Ayetoro and Awoye for Fluoride; 0.12 ppm in Awoye to 0.31 and 0.3 ppm in Ilepete for Cr; 0.04 in Ayetoro, Gbawiyo, Araromi and Pepe to 0.11 and 0.1 ppm in Awoye respectively for Cd. Sabomi (control site) showed low levels of most metals except calcium (Ca) compared with these of oil producing sampling site studied thus suggesting the metal constituent infiltration from oil pollutants in this area.
