Abstract :
Pilot testing was undertaken prior to a
bioassay to be carried out using Tilapia Zillii as the test
model which would be exposed to liquid habitats from
River Challawa, Kano State, to access the differential
bioaccumulation of heavy metals (Pb, Cr, Cd, Al, Zn, Cu
and Fe) to liver and skeletal muscles. A pilot study is a
reflection of the procedure of the main (large scale) study
and is used to validate the feasibility of every part of the
study protocol. From the physicochemical and heavy
metals of the test liquid habitat and the control, all the
parameters assayed for where above the maximum
permissible limit set by Federal ministry of Environment
for surface water, dissolved oxygen however was below
6.0 mg/L which is required for optimal metabolism of
Tilapia zillii and subsequently, aerators were introduced
to increase their chances of survival throughout the
period of the bioassay. After the exposure for 24 hours to
the test liquid habitat and control, liver and skeletal
muscle tissues were analyzed for heavy metals and iron
had the highest in both tissues and across the liquid
habitats, with the concentration of 4.138 to 9.276 mg/kg
for liver tissues across the liquid habitats and 2.812 to
6.857 mg/kg for skeletal muscle across the liquid habitats,.
Finding of the pilot testing, indicate that the feasibility of
the main (large scale) study is achievable with alteration
in few areas such as: introduction of aerators and the
duration
