WebOct 24, 2024 · Cypermethrin was detected in 48 out of the 110 samples. The average lower concentration was 0.08 mg/kg in Okra samples while higher concentration was 0.28 mg/kg found in Cabbage samples. The residues of Cypermethrin were above MRL in 12 samples. Fenvalerate residues were detected in 39 out of the 110 samples. WebEMDLs using NCI GC/MS/MS have been estab- lished for water and sediment that are well below the toxicity of type II pyrethroids such as cyfluthrin and permethrin. Analysis of pyrethroids by this technique yields the sub-ppb detection limits that are required to ensure the safety of aquatic organisms. References 1. Weston D. P., Holmes R. W.,
