Floating Treatment Wetlands Receiving Pesticide Mixtures

Significance:

  • Neonicotinoid pesticides are ubiquitous in both urban and agricultural streams

  • Cause paralysis and death to non-target organisms, such as honeybees, through photo-transformation resulting in highly toxic byproducts

Objective:

  • Evaluate the implications of pesticides on nitrogen removal and pesticide toxic byproduct formation in floating treatment wetlands

Hypothesis:

  • Floating treatment wetlands will remove insecticides will limit nitrogen removal.

Preliminary Conclusions:

  • Pesticides added to floating treatment wetlands have the potential to be removed and enhance nitrate removal.
