- Abstract
This article discusses the occurrence and fate of the insect growth regulator, methoprene, primarily used for mosquito control in the urban areas of Ontario, Canada. The degradation of methoprene and its metabolites were investigated in both hydrologic source areas and receiving bodies of water. The analysis was performed using gas chromatograph – mass spectrometry. The authors concluded that methoprene concentrations in outfall effluents show marked concentration decreases over relatively short time periods and dissolved methoprene and its derivatives are quickly flushed from catch basins during precipitation events. Also, although methoprene is generally not detected in receiving waters, concentrations of metabolites sometimes exceeded those of methoprene. As a result, the metabolites, particularly methoprene acid, should be considered in any assessment of potential environmental impacts.
