The exposure of midwives to nitrous oxide in four hospitals was measured with personal samplers. In three of the four hospitals the average exposure was not significantly less than 100 parts per million (ppm). In one hospital the average exposure was 360 ppm; this was reduced by a factor of about 2.5 when a trial scavenging system was used. Differences in working practices and in the layout, si...

During summer 1991, we collected indoor, outdoor, and personal ozone concentration data as well as time-activity data in State College, Pennsylvania. These concentrations were measured for 23 children and their homes using passive ozone samplers. Outdoor concentrations were also measured at a stationary ambient monitoring site. Results from this pilot study demonstrate that fixed-site ambient m...

OBJECTIVE To investigate the differences between measurements of personal exposure to particulate air pollution and static area measurements in a group of people working close to traffic and to determine whether such differences might obscure any threshold for health effects in epidemiological studies. METHODS Personal air sampling was carried out on two groups of eight traffic wardens for fo...

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...

The effect of exposure to carcinogenic polycyclic aromatic hydrocarbons adsorbed onto respirable air particles (PM2.5, diameter < 2.5 μm) on DNA adducts and chromosomal aberrations was repeatedly studied in Prague, Czech Republic, in groups of policemen working in the downtown area and in bus drivers. Personal exposure was evaluated using personal samplers during working shifts. DNA adducts wer...
