were analyzed using GC/MS equipped with a CI source and quantified using a known amount of
deuterated internal standard. The internal standard was added to the samples after the
extraction.
All recovery data and LODs (limits of detection) were measured as part of the cyfluthrin field
residue program. 3-17
Recoveries ranges of cyfluthrin were as follows:
