<p>The use of Glutathione-S-transferase (GST) activities in earthworm tissue as tool for assessment heavy metal pollution abattoir soils was evaluated this study. Five (5) replicates each species (<em>Libyodrilus violaceous</em>, <em>Eudrilus eugeniae</em> and <em>Alma millsoni</em>), soil rumen waste samples were collected from three (3) sites (Lafenwa, Gbonogun Madojutimi abattoirs) a control site located within Federal University Agriculture Abeokuta, beside an undisturbed stream with no waste. Heavy (Cu, Zn, Pb, Cd, Co, Cr, Ni Mn) concentrations waste, tissues determined using Atomic Absorption Spectrophotometer. The pH organic matter (OM) the by standard methods. GST through conjugation 1mM reduced glutathione (GSH) 1-chloro-2,4-dinitrobenzene (CDNB). recorded significantly higher (p ≤ 0.05) % OM, level than their respective soils. mean Cu, Cd Mn highest obtained Lafenwa abattoir. A abattoirs. <em>Libyodrilous violaceus </em>obtained activity (8.47±1.39) followed ones (8.21±0.85). significant positive correlations observed between concentrations. can therefore be used to assess soils.</p><p><em>Keywords</em>: Glutathione-S-transferase, Biomarker, Earthworms, metals, Abattoir</p>
