Determination of N-Nitrosamines by Gas Chromatography Coupled to Quadrupole–Time-of-Flight Mass Spectrometry in Water Samples
An analytical method based on high-resolution quadrupole–time-of-flight (QToF) mass spectrometry has been developed as an alternative to the classical method, using a low-resolution ion trap (IT) analyzer to reduce ...
Reaction of phenazone-type drugs and metabolites with chlorine and monochloramine
This work studies the chlorination and monochloramination reaction kinetics of two phenazone-type drugs (phenazone – Phe and propyphenazone – PrPhe) and three metabolites of phenazone-type drugs (4-formylaminoantipyrine – ...
First nation-wide estimation of tobacco consumption in Spain using wastewater-based epidemiology
Wastewater-based epidemiology (WBE) has become a very useful tool to monitor a population's drug consumption or exposure to environmental and food contaminants. In this work, WBE has been applied to estimate tobacco ...
