  • Contribution of various microenvironments to the daily personal exposure to ultrafine particles: Personal monitoring coupled with GPS tracking

    • Exposure to ultrafine particles (UFP) may have adverse health effects. Central monitoring stations do not represent the personal exposure to UFP accurately. Few studies have previously focused on personal exposure to UFP. Sixty non-smoking residents living in Copenhagen, Denmark were asked to carry a backpack equipped with a portable monitor, continuously recording particle number concentrations (PN), in order to measure the real-time individual exposure over a period of similar to 48 h. A GPS logger was carried along with the particle monitor and allowed us to estimate the contribution of UFP exposure occurring in various microenvironments (residence, during active and passive transport, other indoor and outdoor environments) to the total daily exposure. On average, the fractional contribution of each microenvironment to the daily integrated personal exposure roughly corresponded to the fractions of the day the subjects spent in each microenvironment. The home environment accounted for 50% of the daily personal exposure. Indoor environments other than home or vehicles contributed with similar to 40%. The highest median UFP concentration was obtained during passive transport (vehicles). However, being in transit or outdoors contributed 5% or less to the daily exposure. Additionally, the subjects recorded in a diary the periods when they were at home. With this approach, 66% of the total daily exposure was attributable to the home environment. The subjects spent 28% more time at home according to the diary, compared to the GPS. These results may indicate limitations of using diaries, but also possible inaccuracy and miss-classification in the GPS data. (C) 2015 Elsevier Ltd. All rights reserved.

  • Ultrafine Particles: Exposure and Source Apportionment in 56 Danish Homes

    • ABSTRACT: Particle number (PN) concentrations (10−300 nm in<br /> size) were continuously measured over a period of ∼45 h in 56<br /> residences of nonsmokers in Copenhagen, Denmark. The highest<br /> concentrations were measured when occupants were present and<br /> awake (geometric mean, GM: 22.3 × 103 cm−3), the lowest when the<br /> homes were vacant (GM: 6.1 × 103 cm−3) or the occupants were<br /> asleep (GM: 5.1 × 103 cm−3). Diary entries regarding occupancy and<br /> particle related activities were used to identify source events and<br /> apportion the daily integrated exposure among sources. Source<br /> events clearly resulted in increased PN concentrations and decreased<br /> average particle diameter. For a given event, elevated particle<br /> concentrations persisted for several hours after the emission of fresh<br /> particles ceased. The residential daily integrated PN exposure in the<br /> 56 homes ranged between 37 × 103 and 6.0 × 106 particles per cm3·h/day (GM: 3.3 × 105 cm−3·h/day). On average, ∼90% of<br /> this exposure occurred outside of the period from midnight to 6 a.m. Source events, especially candle burning, cooking, toasting,<br /> and unknown activities, were responsible on average for ∼65% of the residential integrated exposure (51% without the unknown<br /> activities). Candle burning occurred in half of the homes where, on average, it was responsible for almost 60% of the integrated<br /> exposure.

  • Characterization of indoor aerosol temporal variations for the real-time management of indoor air quality
  • 2015
  • Ingår i: Atmospheric Environment. - Elsevier. - 1352-2310. ; 118, s. 107-117
  • Tidskriftsartikel (refereegranskat)abstract
    • The study presents the characterization of dynamic patterns of indoor particulate matter (PM) during various pollution episodes for real-time IAQ management. The variation of PM concentrations was assessed for 20 indoor activities, including cooking related sources, other thermal sources, personal care and household products. The pollution episodes were modelled in full-scale test chamber representing a standard usual living room with the forced ventilation of 0.5 h(-1). In most of the pollution episodes, the maximum concentration of particles in exhaust air was reached within a few minutes. The most rapid increase in particle concentration was during thermal source episodes such as candle, cigarette, incense stick burning and cooking related sources, while the slowest decay of concentrations was associated with sources, emitting ultrafine particle precursors, such as furniture polisher spraying, floor wet mopping with detergent etc. Placement of the particle sensors in the ventilation exhaust vs. in the centre of the ceiling yielded comparable results for both measured maximum concentrations and temporal variations, indicating that both locations were suitable for the placement of sensors for the management of IAQ. The obtained data provides information that may be utilized considering measurements of aerosol particles as indicators for the real-time management of IAQ. (C) 2015 Elsevier Ltd.
