Removing Disturbing Matrix Constituents from Biota Extracts from Total Extraction and Silicone‐Based Passive Sampling

Environmental Toxicology and Chemistry, Volume 40, Issue 10, Page 2693-2704, October 2021., 2021
Abstract Contaminant analysis in biota extracts can be hampered by matrix interferences caused by, for example, co‐extracted lipids that compromise the quality of the analytical data and require frequent maintenance of the analytical instruments. In the present study, using gas chromatography coupled to high resolution mass spectrometry (GC‐HRMS), we ...

CYP450-Dependent Biotransformation of the Insecticide Fipronil into Fipronil Sulfone Can Mediate Fipronil-Induced Thyroid Disruption in Rats (Full paper and erratum)

, 2012
In rats, the widely used insecticide fipronil increases the clearance of thyroxine (T-4). This effect is associated with a high plasma concentration of fipronil sulfone, the fipronil main metabolite in several species including rats and humans. In sheep,
