ASSESSMENT OF HEAVY METALS IN THE SEDIMENTS OF OKE-AFA CANAL,LAGOS,NIGERIA

abdulrazaq yahaya

Abstract


Sediments (sample) at nine different sampling points along oke-afa canal, Isolo Lagos (figure 1.0) were analyzed for heavy metals, to determine their level of pollution. The levels of heavy metals in some of the samples were not detectable. The results are then compare with maxim permissible limit (MPL) in the world wide soils and fresh water sediments (USPH), zinc (87-431 mg/kg); lead (range ND-45 mg/kg) cadmium (range ND -16 mg1kg) and Nickel (range ND- 6mg/kg).

KEY WORDS: sediments, Heavy metal, pollution assessment, Oke-Afa canal.
