Labeo rohita, a bioindicator for water quality and associated biomarkers of heavy metal toxicity

Abstract This study investigated the effect of heavy metals on Labeo rohita inhabiting the Yamuna River, India. Levels of heavy metals measured in the water were as follows: Fe>Mn>Zn>Cu>Ni>Cr>Cd. Gill and liver tissue of exposed L. rohita showed a high metal pollution index, compar...
