General description

Azamethiphos is classified under the heterocyclic organothiophosphate group of compounds.

Application

Azamethiphos may be used as an analytical reference standard for the determination of azamethiphos in:
  • Salmon feed samples by ultra-high performance liquid chromatography combined with traveling-wave ion mobility/quadrupole time-of-flight mass spectrometry (UHPLC-TWIMS-QTOFMS).
  • Surface water samples by solid-phase extraction (SPE) and LC coupled to quadrupole-Orbitrap high resolution tandem mass spectrometry (Q-Orbitrap-MS).
  • Fish fillet samples by QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction and LC-QTOFMS.
  • Human serum samples by QuEChERS combined with LC coupled to tandem mass spectrometry (MS/MS).

Conventional in vitro assays sometimes fail to reveal esterase inhibition by piperonyl butoxide (PBO), although synergism studies suggest loss of esterase-mediated sequestration of insecticide does take place. A new in vitro assay has been devised that routinely reveals binding between

Here, we identify and characterise cholinesterase (ChE) and carboxylesterase (CbE) activities in the body tissues of the sediment dwelling worm Arenicola marina. Exposure to the organophosphorus pesticide azamethiphos yielded an in vitro IC50 of 5 microg l(-1) for propionylcholinesterase (PChE).

Acetylcholinesterase (AChE) is the target of a major pesticide family, the organophosphates, which were extensively used as control agents of sea lice on farmed salmonids in the early 1990s. From the mid-1990s the organophosphates dichlorvos and azamethiphos were seriously compromised

Pesticides are used extensively in the finfish aquaculture industry to control sea lice infestations on farmed salmon. The most prevalent method of use is to enclose a net pen with an impervious tarpaulin and mix a pesticide solution within that
