WebIon 2, dissociate to new product ions, scan mass spectrum. Cypermethrin elutes off the column as a group of isomer peaks, therefore there is a need for group summing of the ions in a large time window. Cypermethrin is a late eluter (late retention time), and this is where the matrix from the sample extract elutes as well. The Cypermethrin is moderately toxic through skin contact or ingestion. It may cause irritation to the skin and eyes. Symptoms of dermal exposure include numbness, tingling, itching, burning sensation, loss of bladder control, incoordination, seizures and possible death. Pyrethroids may adversely affect the central nervous system. Human volunteers given dermal doses of 130 μg/cm on the earlobe experienced local tingling and burning sensations.

WebThe concentration of cypermethrin has a specific range for killing fire ants in an efficient manner. Neither a very low nor a very high concentration of cypermethrin was able to kill fire ants efficiently. The most effective concentration of cypermethrin was 0.13% in DDGS when mixed with 15% shrimp shell powders and 11% soybean oil. WebResidue analytical methods for cypermethrin rely on GC-ECD and GC-MS. Typical LOQs achieved for plant and animal commodities fall in the range of 0.01–0.05 mg/kg.
