Bifenthrin is NOT immobile, as well as being quite persistent

Note the following article, entitled: "Distribution and persistence of pyrethroids in runoff sediments".  This journal article supports the observation that Bifenthrin is NOT immobile, as well as being quite persistent.

"Pyrethroids are commonly used insecticides in both agricultural and urban environments. Recent studies showed that surface runoff facilitated transport of pyrethroids to surface streams, probably by sediment movement.  Sediment contamination by pyrethroids is of concern due to their wide-spectrum aquatic toxicity."

The article then waxes extremely technical, however it clearly and strongly shows that pyrethroid contaminants such as Bifenthrin and Permethrin showed up as residues in eroded sediment along a runoff path of 260m!  The contaminant "enrichment" was apparently selective because it coincided with the runoff pathway enrichment of sediment "clay fractions" and "organic carbon" or, in other words, "organic matter and chemical-rich fine particles."

And, as to persistence?  "Long persistence was observed for BF [Bifenthrin] under both aerobic and anaerobic conditions, and the half-life ranged from 8 to 17 mo at 20 [Degrees] C...  The significant enrichment, along with the prolonged persistence, suggests that movement of pyrethroids to the surface water may be caused predominantly by the chemically rich fine particles."

The article, on the basis of this recognition of the mobility and persistence in pyrethroid contaminants, strongly argues for "mitigation strategies to reduce offsite movement of fine sediment."
