  1. 1. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air

    Author : Hanna Söderström; Mats Tysklind; Per-Anders Bergqvist; Jochen F. Muller; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; air pollution; alkyl-PAHs; atmosphere; bioavailability; boundary layer; diffusive sampling; emissions; integrative; membrane; monitoring; nitro-PAHs; PAHs; particles; passive samplers; PCBs; plants; PRCs; release rate; sampler design; sources; SPMDs; traffic; uptake rate; wind effect; wood burning; Miljökemi; Environmental chemistry; Miljökemi;

    Abstract : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. READ MORE

  2. 2. Levels and sources of organophosphorus flame retardants and plasticizers in indoor and outdoor environments

    Author : Anneli Marklund; Peter Haglund; Barbro Andersson; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organophosphate esters; OPs; human exposure; air; dust; sewage treatment plants; sludge; oil; snow; deposition; flame retardants; plasticizers; analysis; TCEP; TPP; TCPP; TBP; TBEP; Environmental chemistry; Miljökemi;

    Abstract : Global consumption of organophosphate esters (OPs), which are used as flame retardants and plasticizers, is rapidly increasing. Their use as additives in diverse applications poses a risk as they may be emitted from the products they are added to and be further transported in the environment. READ MORE

  3. 3. Extensive green roofs in Porto Alegre, Brazil : Effect on indoor thermal comfort in residential buildings

    Author : Lisandra Fachinello Krebs; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Computer simulations; Extensive green roofs; Housing projects; Indoor thermal comfort; Leaf area index; Microclimate; Social housing; Sustainability; Thermal comfort;

    Abstract : Brazil had a significant quantitative housing deficit of 7.7 million residences in 2015, especially in low-income housing. Traditionally, these projects have low levels of thermal insulation which can result in discomfort caused by warmth or cold. The residential sector is responsible for a significant part of the energy use in Brazil. READ MORE

  4. 4. Contribution of polyfluoroalkyl phosphate esters (PAPs) and other precursor compounds to perfluoroalkyl carboxylates (PFCAs) in humans and the environment

    Author : Ulrika Eriksson; Anna Kärrman; Bert van Bavel; Gunilla Lindström; Jonathan Martin; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; PAPs; precursors; PFCA; exposure; indoor dust; human serum; WWTP; bird eggs; Kemi; Chemistry;

    Abstract : Per-and polyfluoroalkyl substances (PFAS) are anthropogenic compounds that have been spread all over the world. The use of fluorotelomer compounds, short-chained homologues, and other PFASs with perfluorinated moieties has emerged recent years. READ MORE

  5. 5. Fine and Ultrafine Particles from Combustion Sources - Investigations with In-situ Techniques

    Author : Joakim Pagels; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; Teknik; Technological sciences; Indoor Air; In-Situ Measurement; Biomass Combustion; Morphology; Hygroscopic Growth; Volatility; TDMA; APS; ELPI; Respiratory Deposition; Fine Particles; Miljöteknik; kontroll av utsläpp; Ultrafine Particles;

    Abstract : Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. READ MORE
