   Författare :Deguo Kong; Ian Cousins; Matthew MacLeod; Mick Whelan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; emerging chemicals; climate change; fate; multimedia model; risk assessment; physical-chemical property; uncertainty; Arctic; Baltic; time series; persistent organic pollutants; temporal trend; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Both chemical-specific (e.g. physical-chemical properties) and environmental (e.g. LÄS MER

3. 2. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents

   Författare :Pierre Oesterle; Stina Jansson; Jerker Fick; Ulrika Rova; Capucine Dupont; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Activated biochars; HTC; regeneration; analytical chemistry; adsorption; degradation; nontarget analysis; wastewater; circular economy; emerging contaminants; surface chemistry; Analytical Chemistry; analytisk kemi; environmental science; miljövetenskap; Pharmaceutics; galenisk farmaci; analytisk materialfysik; analytical material physics; Analytical Pharmaceutical Chemistry; analytisk farmaceutisk kemi;

   Sammanfattning : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. LÄS MER

4. 3. 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.

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

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

   Sammanfattning : 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. LÄS MER

7. 5. Organohalogen contaminants in wildlife from the Yangtze River Delta : Development of methods and assessments of legacy and emerging persistent organic pollutants

   Författare :Ge Yin; Åke Bergman; Gang Yu; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organochlorine pesticides; flame retardants; chlorinated paraffins; PCBs; PCDEs; PBDEs; PCDD Fs; dicofol; environmental monitoring; bioindicator; shellfish; snail; bird eggs; miljökemi; Environmental Chemistry;

   Sammanfattning : Rapid economic development has occurred during the past few decades in China with the Yangtze River Delta (YRD) area as one of the most progressive areas. The urbanization, industrialization, agricultural and aquaculture activities result in extensive production and application of chemicals. LÄS MER
