Fecha de publicación: 25/10/2024 Fuente: EU Reference Laboratories for Residues of Pesticides. Fruits and vegetables A new QuEChERS-based LC-MS/MS method was developed
allowing determination of cypermethrin-related residues in
food. LC-MS/MS achieves a good resolution of the four
cypermethrin enantiomeric pairs and circumvents the
quantification problems occurring in GC-applications due
to thermal isomerization. Sufficient sensitivity was
achieved to allow controlling the current MRLs of
cypermethrin and to separately quantify the share of the
toxicologically critical alpha-cypermethrin (cis-II) at
these levels. ...
