Etheria elliptica a sessile organism was also used to determine the concentration of heavy metal in the aquatic environmental. In water, Cu had the highest concentration (0.55 &amp;ndash; 0.13 mgl &amp;plusmn;0.1) while in sediments, the highest value obtained was in Fe (1.463.89mgl&amp;plusmn;0.27). The minimum concentrations recorded were in Pb; which was below detectable level. The result also revealed that the shell accumulate more heavy metals than the flesh of the mussel with Cu in the shell exhibiting a negative correlation with all the metals in the flesh. However, the condition factor (K) value is 6.44, an indication of good health. The lengthweight relationship is expressed as W 0.48 x L 1.94 (r2 0.29) showing the growth pattern to be negatively allometric. </abstract> <index>Open Science Index 99, 2015</index> </article>
