Abstract: (3540 Views)

Pirimicarb, carbamate, Bio-pesticide and lead are classified as the most common environmental pollutants, which may have different effects on each other and on aquatic organisms. The aim of this study is to evaluate the synergistic and antagonistic effects of Pirimicarb and Bithurin pesticides on lead bio-accumulation in freshwater snail (Lymnaea truncatula). Snails in a completely randomized design were exposed to different sub-lethal concentrations of Pirimicarb (0.0, 0.5 and 1 mg. L^-1) and Bithurin (0.0, 0.5 and 1 mg.L^-1) alone and together with lead (0.0, 0.1 and 0.2 mg.L^-1) for 8 days. By raising the concentration of Pirimicarb ranged from 0.5 to 1 mg.L^-1, lead accumulation was increased in the tissue of snails, but with increasing Bithurin concentration from 0.5 to 1 ml.L^-1, the accumulation of lead in the tissue of snails did not show a significant increase compared tosnails exposed to lead alone. The results of this study indicate that the synergistic effects of Pirimicarb on the bioaccumulation of lead in the snail tissue depend on the concentration of this pesticide in water, but Bithurin bio-pesticide in the high concentration of lead has a synergistic effect on lead accumulation. These results also indicate that freshwater snails (L. truncatula) can be used as a useful indicator for assessing and monitoring the environment, especially the aquatic ecosystems contaminated with heavy metals and pesticides.
