Determination of steroid hormone residues in farmed fish using high-resolution orbital ion trap mass spectrometry

Abstract

A method for determination of 15 steroid hormones in farmed fish by liquid chromatography–orbital ion trap mass spectrometry has been developed and validated. The method involved sample preparation with the...

Quantification of 37 glucocorticoids in chicken muscle by UHPLC-Q-Orbitrap-MS with parallel reaction monitoring

“…Compared to our previous research on quantifying steroids in fish muscles using UHPLC-Q-Orbitrap-MS with selected ion monitoring (SIM) scan mode, 22 this PRM method with targeted data acquisition presented in this study provides comprehensive fragment information through higher-energy collisional dissociation (HCD). Furthermore, unlike triple quadrupole MS, this approach offers high-resolution and high-accuracy mass measurements, facilitating precise identification of target compounds.…”

“…The sample preparation with the SPE cartridge was modified based on our previous report 22 with some modifications. Briefly, the homogenized samples were transferred to a 15 mL polypropylene centrifuge tube.…”

Distribution and Probabilistic Risk Assessment of Antibiotics, Illegal Drugs, and Toxic Elements in Gastropods from Southeast China

“…In addition to antibiotics, the illegal use of drugs in aquaculture, including veterinary drugs and growth promoters, has raised serious concerns. For instance, our previous report discovered steroid hormone residues in farmed fish [6]. Malachite green (MG), initially used for treating parasitic, fungal, and protozoan diseases in aquaculture, is legally restricted or prohibited in many countries due to its toxic effects on humans, including potential carcinogenic properties and risks to the liver and kidney [7].…”

Benzoyl isothiocyanate modified surface of silica gel as the extraction material for adsorbing steroid hormones in water

“…21 Thus, an efficient pretreatment method is extremely important for the detection of steroid hormones. [22][23][24] In recent years, some new materials have shown good enrichment efficiency in various water environments such as surface water and wastewater. For example, mixed-mode cation exchange, 25 molecularly-imprinted polymers, 26 and primary and secondary amines 27 have been prepared for the solid-phase extraction of steroid hormones in complex aqueous matrices.…”
