title: Assessment of pesticide residues in Karaboğaz Lake from Kızılırmak Delta, Turkey.
abstract: Monitoring of pesticide residues in water and sediments was conducted for the coastal shallow Karaboğaz Lake, northern Turkey. During a one-year study period, eight pesticides (malathion, etofenprox, molinate, oxamyl, propamocarb hydrochloride, tebufenozide, linuron, piperonyl butoxide) were detected in water and in sediments, all at μg/L and μg/kg concentrations, respectively. Temporal variation in pesticide concentrations was observed. Highest pesticide concentrations in water and sediment were from tebufenozide and etofenprox, respectively. Aquatic risk assessments revealed that out of eight pesticides detected, three showed unaccaptable risk: malathion, oxamyl and etofenprox.
