Use Of Snails As Bioindicators Of Mercury Pollution In Aquatic Ecosystems

ABSTRACT

Cross-sectional field and experimental studies were carried out to determine the mercury distribution in the Mabubi River and to establish its biological effects in the ecosystem using snails as bioindicators. The median and range for total mercury concentration in Lymnaea stagnaliswere 4298 and 12.62 to 50618 respectively. The total mercury concentrations were recorded as below the detection limit (
