The Physico-Chemical Analysis of Water Sample from Fish Pond, Department of Animal Production Technology, Ramat Polytechnic, Maiduguri, Borno State, Nigeria

Abstract

The determination of physico-chemical parameters in water sample collected from fish pond, Department of Animal Production Technology, Ramat Polytechnic, Maiduguri was conducted in June 2016. Water samples were collected at four locations established in the fish pond and homogenized to form a representative sample, then analysed using standard procedures. The metal elements of Ca, Cu, Cd, Cr, Mn, Ni, Pb and Zn of the water samples were determined by Flame Atomic Absorption Spectrophotometer. The physical parameters pH, temperature and dissolved oxygen were also determined using standard procedures. The concentration levels of metal elements in water sample were: Ca (43.40)mg/l, Cu (0.48)mg/l, Cd (0.30)mg/l, Cr (0.39)mg/l, Mn (0.11)mg/l, Ni (1.48)mg/l, Pb (0.50)mg/l and Zn (0.70)mg/l while physical parameters temperature was 28oC, pH was 6.9 and dissolved oxygen was 7.0mg/l. The results showed presence and concentration levels of all the parameters analysed. Most of the metals analysed were within the maximum levels set by WHO and NAFDAC, except Ni, Cr and Pb that exceeded the permissible limit set by WHO and NAFDAC.
