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

    Author : Seth Newton; Cynthia de Wit; Ulla Sellström; Matthew MacLeod; Roland Kallenborn; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Environmental Assessment of Green Chemicals - LCA of Bio-Based Chemicals Produced Using Biocatalysis

    Author : Linda Tufvesson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green chemicals; industrial biotechnology; Life cycle assessment; renewable resources;

    Abstract : It is of at most importance that society reduces its impact on the environment. In the chemical industry the use of renewable resources will play a fundamental role in the transition to more sustainable chemical products. Also industrial biotechnology, i.e. READ MORE

  6. 4. Environmental Assessment of Emerging Routes to Biomass Based Chemicals The Case of Ethylene

    Author : Christin Liptow; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; sugarcane; time lags; gasification; biomass based chemicals; wood; land use; life cycle assessment; ethylene; LCA;

    Abstract : The production of bulk chemicals from biomass instead of fossil resources is perceived as one promising option to decrease society's environmental impact. However, though considerable research and development efforts aim at such production, it might take several more years before biomass based bulk chemicals are fully commercialized. READ MORE

  7. 5. Remediation of per- and polyfluoroalkyl substance-contaminated soil and groundwater, using electrokinetic and stabilisation methods

    Author : Georgios Niarchos; Fritjof Fagerlund; Anett Georgi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAS; contamination; emerging contaminants; forever chemicals; pollution; soil; groundwater; remediation; electrokinetic; stabilisation; activated carbon;

    Abstract : Per- and polyfluoroalkyl substances, commonly known as PFAS, are emerging contaminants with a worldwide environmental distribution and a concerning (eco)toxicological profile. The omnipresence of PFAS in various environmental media poses risks to the quality of our drinking water sources. READ MORE
