Total daily intakes of diethyl phthalate (DEP), di(n-butyl) (DnBP), di(isobutyl) (DiBP), butyl benzyl (BBzP) and di(2-ethylhexyl) (DEHP) were calculated from metabolite levels measured in the urine 431 Danish children between 3 6 years age. For each child intake attributable to exposures indoor environment via dust ingestion, inhalation dermal absorption estimated collected child's home daycare center. Based on samples, DEHP had highest total (median: 4.42 µg/d/kg-bw) BBzP lowest 0.49...

Abstract. Mercury (Hg) is a worldwide contaminant that can cause adverse health effects to wildlife and humans. While atmospheric modeling traces the link from emissions deposition of Hg onto environmental surfaces, large uncertainties arise our incomplete understanding processes (oxidation pathways, deposition, re-emission). Atmospheric reactivity exacerbated in high latitudes there still much be learned polar regions terms processes. This paper provides synthesis monitoring data available...

Data from a nationwide survey on the status of Swedish residential building stock and indoor air quality was placed in public domain by National Board Housing, Building Planning Sweden. The current research investigates humidity conditions buildings, single-family houses apartments, assessing measurements extensive BETSI-survey against adjusted relative levels based existing norms Standards. aim this study is to investigate associations correlations between multiple system characteristics,...

The oxidation of SO2 by O3 on mineral dust was studied using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Formation sulfate observed the surface. A two-step mechanism that involves physisorbed followed is presented. formation rate determined to be first order with respect and zero in O3. reactive uptake coefficient, γ, from absorbance, calibrated ion chromatography, geometric or BET surface area. γSO2 independent concentration 10−3 area, 10−7 area for [SO2] = 2.2 ×...

Given the rate at which humans shed their skin (desquamation), flakes that contain squalene and cholesterol are anticipated to be major constituents of indoor dust. These compounds have been detected in more than 97% dust samples collected from 500 bedrooms 151 daycare centers young children living Odense, Denmark. The mass fractions were approximately log-normally distributed (homes: GM = 32 μg/g, GSD 4.3; centers: 11.5 4.3); those displayed a poorer fit such distribution 625 3.4; 220 4.0)....

The present study aimed at investigating the effects of ventilation strategies on indoor air quality (IAQ) in schools. Measurements thermal environment and IAQ were performed over 5 school days 45 primary classrooms Gothenburg, Sweden, grouped into three categories according to their system: category A) natural or exhaust ventilation, automated window opening; B) balanced mechanical systems with constant volume (CAV) C) variable (VAV). equally well respect temperature relative humidity...

This study aimed to better understand and quantify the influence of ventilation strategies on occupant-related indoor air chemistry. The oxidation human skin oil constituents was studied in a continuously ventilated climate chamber at two exchange rates (1 h-1 3 ) initial ozone mixing ratios (30 60 ppb). Additional measurements were performed investigate effect intermittent ("off" followed by "on"). Soiled t-shirts used simulate presence occupants. A time-of-flight-chemical ionization mass...

Consumer goods and building materials present in the preschool environment can be important sources of hazardous chemicals, such as plasticizers, bisphenols, organophosphorus brominated flame retardants, poly- perfluoroalkyl substances, which may pose a health risk to children. Even though exposure occurs via many different pathways, food intake, inhalation, dermal exposure, mouthing toys etc., dust has been identified valuable indicator for indoor exposure. In study, we evaluate efficiency...

A major component of human skin oil is squalene, a highly unsaturated hydrocarbon that protects the from atmospheric oxidants. Skin oil, and thus continuously replenished on surface. Squalene also quickly consumed through reactions with ozone other This study examined extent squalene depletion in oils forearm volunteers after exposure to climate chamber. Temperature, relative humidity (RH), coverage by clothing, participants' age were varied controlled manner. Concentrations determined wipe...

The heterogeneous reactions of oxides nitrogen with NaCl as a model for sea salt particles have been the focus many studies, due to their potential act precursors atomic halogens in troposphere. While great deal has learned about kinetics and mechanisms reactions, it is not clear how well this extrapolates complex mixture inorganics found salt. We report here diffuse reflectance infrared Fourier transform spectrometry (DRIFTS) studies which nitrate formation on surface followed time during...

In this article, gas-phase advanced oxidation, a new method for pollution control building on the photo-oxidation and particle formation chemistry occurring in atmosphere, is introduced characterized. The process uses ozone UV-C light to produce situ radicals oxidize pollution, generating particles that are removed by filter; using MnO2 honeycomb catalyst. This combination of processes removes wide range pollutants with comparatively low specific energy input. Two proof-of-concept devices...
