WebBifenthrin is poorly soluble in water and often remains in soil. Its residual half-life in soil is between 7 days and 8 months, depending on the soil type, with a low mobility in most soil types. Bifenthrin has the longest known residual time in soil of insecticides currently on the market. It is a white, waxy solid with a faint sweet smell. WebAug 4, 2024 · For the cypermethrins, the points of departure (PODs) for clinical signs after single or repeated exposure are comparable across durations of exposure. Thus, consistent with this class of compounds, neurotoxicity is not considered to progress with repeated exposure. Therefore, repeated dosing is essentially a series of acute exposures.
