Description:
A pesticide runoff event was simulated on two 10mx50m constructed wetlands (one non-vegetated, one vegetated) to evaluate the fate of methyl parathion (MeP) (Penncap-M^(R)). Water, sediment, and plant samples were collected at five sites downstream of the inflow for 120d. Semi-permeable membrane devices (SPMDs) were deployed at each wetland outflow to determine exiting pesticide load. MeP was detected in water at all locations of the non-vegetated wetland (50m), 30min post-exposure. MeP was detected 20m from the vegetated wetland inflow 30min post-exposure, while after 10d it was detected only at 10m. MeP was measured only in SPMDs deployed in non-vegetated wetland cells, suggesting detectable levels were not present near the vegetated wetland outflow. Furthermore, mass balance calculations indicated vegetated wetlands were more effective in reducing aqueous loadings of MeP introduced into the wetland systems. This demonstrates the importance of vegetation as sorption sites for pesticides in constructed wetlands.
