The Swedish National Food Administration in Uppsala and the Karolinska Institute in Stockholm have been looking at the potential toxicity of musks following their discovery in human milk, when mothers are breastfeeding.1
Scientists set out to correlate the use of perfumed products during pregnancy monitoring the amount of seven synthetic musks in the breast milk of Swedish women. The milk samples underwent liquid–liquid extraction and the lipids were removed by gel permeation chromatography. Final extractions were analysed by GC–MS with electron ionization employing two deuterium-labelled synthetic musks as internal standards.
There was a positive correlation between the levels of the polycyclic musks, galaxolide and tonalide but none between the latter two and the nitro musk xylene.

Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
