14 Cyclic volatile methylsiloxanes (cVMS) are used in personal care products and are 15 hydrophobic, volatile and persistent. Their environmental water concentrations are low and 16 are difficult to detect using conventional sampling methods. This study shows the potential of 17 passive sampling for cVMS. We used low-density polyethylene (LDPE) samplers and in-field 18 calibration methods for o...
personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. this work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. velocity profiles have been measured around and within typical cylindrical sampling devices, plac...
Methods Arterial stiffness was measured in 20 healthy volunteers (59-76 years of age) in three locations and at 11 time points during one year: seven times in Leuven (Belgium) and twice during each 10-day stay in Milan (Italy) and Vindeln (Sweden). Pulse Wave Velocity (PWV), distensibility (DC) and compliance (CC) were measured using Esaote MyLabOne ultrasound. Personal NO2 exposure, an indicat...
