Iron Deficiency Is a Risk Factor for Thyroid Dysfunction During Pregnancy: A Population-Based Study in Belgium
stratified and clustered sampling design. Urine and blood samples were collected, and a questionnaire was completed face to face with the study nurse. Concentrations of free thyroxine (fT4), total thyroxine ...
Development and Validation of a UHPLC-ESI-MS/MS Method for Quantification of Oleandrin and Other Cardiac Glycosides and Evaluation of Their Levels in Herbs and Spices from the Belgian Market
LC-MS/MS oleandrin plant toxins urine VALIDATION Abstract: Cardiac glycosides (CG s) are naturally occurring plant secondary metabolites that can be toxic to humans and animals. The aim of this work was to ...
Risk to human health related to the presence of perfluorooctane sulfonic acid and perfluorooctanoic acid in food
and ?Milk and dairy products?, ?Drinking water? and ?Fish and other seafood? for PFOA. PFOS and PFOA are readily absorbed in the gastrointestinal tract, excreted in urine and faeces, and do not undergo ...
Nicotine Dependence and Urinary Nicotine, Cotinine and Hydroxycotinine Levels in Daily Smokers.
cigarettes per day among biomarker concentrations and individual FTND items. METHODS: Urine samples and questionnaire data of 239 daily smokers were obtained. Nicotine, cotinine and hydroxycotinine urinary ...
Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.
spectrometry (UHPLC- MS / MS) method was developed to measure creatinine in small volumes of human urine. In this method, urine samples are simply diluted with a basic mobile phase and injected directly under ...
The European COPHES/DEMOCOPHES project: towards transnational comparability and reliability of human biomonitoring results.
European countries. These specimens were investigated for six biomarkers (mercury in hair; creatinine, cotinine, cadmium, phthalate metabolites and bisphenol A in urine). The results for mercury in hair are ...
Hair mercury and urinary cadmium levels in Belgian children and their mothers within the framework of the COPHES/DEMOCOPHES projects.
children’s urine was detected at a geometric mean concentration of respectively 0.21 and 0.04 μg/l. For both biomarkers, levels measured in the mothers and their child were correlated. While the urinary ...
On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
spectrometry (UPLC- MS / MS) for the simultaneous detection of nicotine, cotinine and trans-3’-hydroxycotinine in human urine. The advantages of both on-line SPE (speed, automation, less labor intensive) coupled ...
