Organofosfatlı pestisitler Sulak alanlar Tarımsal kirlilik Pilot ölçekli reaktör Meriç - Ergene havzası
With
the widespread use of modern agriculture, the use of pesticides in the world
has increased. As in many countries, pesticide pollution has increasingly been
observed in Turkey due to excessive and unconscious use of pesticides. Meric
Delta, located in the Meric-Ergene Basin and receiving agricultural drainage
from paddy fields, is one of the regions subject to pesticide pollution. In
this study, samples were taken from the wetlands in Meric Delta and the fate of
four organophosphate pesticides (Chlorpyrifos, Dichlorvos, Fenthion, Diazinon)
was investigated in a pilot scale wetland reactor. In the pilot scale reactor
set up to represent wetlands in Meric-Ergene Basin, half-lives and adsorption
amounts of pesticides to plants and sediments were determined. Additionally,
the potential of pesticides for leaching to the groundwater has been determined
by calculating GUS (“Groundwater Ubiquity Score”). The results showed the
effectiveness of free surface flow constructed wetlands in organophosphate
pesticide removal. The results of this study provide key guidelines for the
design of constructed wetlands for the mitigation of organophosphate
pesticides.
