ETUDE DE L'INFLUENCE DU VER DE TERRE LUMBRICUS TERRESTRIS SUR LA CAPACITE COMPLEXANTE DELA SOLUTION DU SOL STUDY OF EARTHWORM INFLUENCE LUMBRICUS TERRESTRIS ON SOIL SOLUTION COMPLEXATION CAPACITY

摘要

Four soil samples highly contaminated with metals of urban and mine origin (SE1, SM2, sm1, sm2) and having different physico-chemical proprieties were selected to study copper complexation capacity (LT) of soil solution. The effect of Lumbricus terrestris on copper complexation capacity of soil solution was investigated on SE1 and SE2. The complexation capacity was estimated by amperometric titration of soil solution by copper.
