  1. 1. Semipermeable membrane devices in monitoring of organic pollutants in the aquatic environment

    Författare :Darius Sabaliunas; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; effect studies; environmental monitoring; organic pollutants; bioconcentration; passive samplers; Semipermeable membrane devices; SPMDs; toxicity; genotoxicity; bioassays; Ecology; Ekologi;

    Sammanfattning : Semipermeable membrane devices (SPMDs) are passive samplers capable of concentrating hydrophobic chemicals from water, sediments, soil and air. They consist of layflat polymeric membrane such as polyethylene containing a thin film of synthetic lipid such as triolein. LÄS MER

  3. 2. Occurrence and fate of emerging and legacy flame retardants : from indoor environments to remote areas

    Författare :Seth Newton; Cynthia de Wit; Ulla Sellström; Matthew MacLeod; Roland Kallenborn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flame retardant; emerging; legacy; polybrominated diphenyl ethers; PBDE; HBCDD; long range transport; dust; air; soil; atmospheric deposition; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Persistent organic pollutants (POPs) are toxic chemicals that can be found in various matrices in all corners of the planet, including remote areas such as the Arctic.  Several POPs are known and monitored but given the abundance of new chemicals in commerce about which little is known, chemicals that may be new POPs are constantly being screened for.

  4. 3. DNA lesions and carcinogenicity from the urban air pollutants 2- and 3-nitrobenzanthrone

    Författare :Eszter Nagy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :3-nitrobenzanthrone; 2-nitrobenzanthrone; diesel exhaust; carcinogenicity; acute toxicity; DNA adducts; oxidative stress; intratracheal; ingestion;

    Sammanfattning : In the early 1990's, Japanese doctors in urban areas discovered an increasing incidence of lung cancer among women, which was not attributed to a change in diet or smoking. This led to a growing investigation of urban air, and subsequently the discovery of 3-nitrobenzanthrone (3-NBA), a pollutant originating from diesel emissions. LÄS MER

  5. 4. Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment

    Författare :Ida Järlskog; Yvonne Andersson-Sköld; Stephan Wagner; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-exhaust particles; tire wear particles; road dust; automated SEM EDX; environmental samples; optimized sample preparation; organic pollutants; street sweeping; traffic-derived microplastics; road simulator;

    Sammanfattning : The prevalence of microplastic contamination has raised concerns about the potential risk and impact on the global environment. Traffic-derived microplastics, i.e., tire wear particles (TWP), polymer-modified bitumen, and road markings contribute to the emissions, and TWP are assumed to be one of the largest sources of microplastic emissions.

  7. 5. Particulate airborne impurities : express analysis and health effects

    Författare :Kai Wilkinson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The cumulative effects of air pollutants are of principal concern in research on environmental protection in Sweden. Post-industrial society has imposed many limits on emitted air pollutants, yet the number of reports on the negative effects from them is increasing, largely due to human activity in the form of industrial emissions and increased traffic flows.
