  As a natural, biological material, wood emits various organic chemical substances, mostly volatile organic compounds (VOCs), very volatile organic compounds (VVOCs) and formaldehyde. When such emissions occur in indoor spaces, concentrations of these substances are higher than concentrations outdoors. Consequently, the level of emissions from building materials are of relevance in relation to their possible health effects. The aim of the study was to test the hypothesis that exposure to VOCs from Scots pine (Pinus sylvestris) might increase mucous membrane symptoms and/or general symptoms, compared to exposure to VOCs from Norway spruce (Picea abies). The study was carried out as a double-blinded, crossover, randomized, controlled trial. The health indicators were measured using objective and subjective methods. The VOC exposure was measured with a proton-transfer-reaction time-of-flight mass spectrometer. Thirty healthy individuals participated. The mean concentration of CO2 inside the chamber in each session varied between 420 ppm and 533 ppm. The temperature and RH varied between 21.5°C and 23.7°C and 12.0% and 24.2%. Ozone was supplied via ventilated outdoor air. The median concentration in outdoor air was 23 μg/m3 (13 ppb). The study was conducted with a statistically significant difference in the exposure to VOCs between the experimental (pine) exposure and the control (spruce) exposure. The mean concentrations of VOCs during the experimental exposure were methanol (31 ppb), acetaldehyde (8 ppb), formic acid (11 ppb), acetone/propanal (14 ppb), acetic acid (14 ppb) and monoterpenes (172 ppb). No difference in health outcome was revealed between the experimental and the control exposure. No inflammatory reactions or sensory irritation were found with exposure to 172 ppb monoterpenes and a low ozone concentration. Low relative humidity may have increased eye blinking in the participants in both exposure situations.

  A high resolution proton-transfer-reaction time-of-flight mass spectrometer (PTR-ToF- MS) was used for on-line and real-time measurements of volatile organic compounds (VOCs) at the Birkenes Observatory in Southern Norway. Measurements were carried out during late spring and summer 2012 and in January and early February 2013. Here we present the obtained PTRMS standard data product which includes volume mixing ratios of methanol, acetonitrile, acetaldehyde, acetone, dimethyl sulphide, isoprene, methacrolein plus methylvinylketone, methylethylketone, benzene, toluene, C8-alkylbenzenes, C9-alkylbenzenes and the sum of the monoterpene isomers. Exploratory data of formic acid, acetic acid, pinonaldehyde and three unidentified signals (m/z 87.080, m/z 89.060 and m/z 101.098) are also shown. PTR-ToF-MS mass spectra were dominated by oxygenated VOCs both in summer and in winter. Pure hydrocarbons were mostly aromatic hydrocarbons (benzene, toluene, C8-alkylbenzenes) in winter and biogenic hydrocarbons (monoterpenes and isoprene) in summer. The summertime data confirm that the Birkenes Observatory is an interesting site in the boreo-nemoral vegetation zone where it is possible to observe both monoterpene and isoprene emissions and their photochemical processing in the atmosphere.
