2. 16. Legacy persistent organic pollutants and chemicals of emerging concern in Sweden : from indoor environments to remote areas

   Author : Seth Newton; Cynthia de Wit; Ulla Sellström; Per Larsson; Annika Jahnke; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; atmospheric deposition; arctic; flame retardant; POP; long range transport; miljökemi; Environmental Chemistry;

   Abstract : Bulk atmospheric deposition samples were taken every two months for a year in 2009-2010 at two sites in northern Sweden and analyzed for a suite of legacy and emerging persistent organic chemicals including legacy organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs)  and novel flame retardants (NFRs).  To further investigate the urban occurrence and contribution to remote contamination of flame retardants, indoor air, ventilation system air, and dust were sampled in several microenvironments in Stockholm during the winter of 2012 for analysis of PBDEs, isomer-specific hexabromocyclododecane (HBCDD), and NFRs.

4. 17. Models of the Distribution of Persistent Organic Pollutants in the Marine Environment

   Author : N. Johan Persson; Dag Broman; Kevin Jones; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; mass balance models; fugacity models; eutrophication; PCDD F; PCB; PCN; soot carbon.; Environmental chemistry; Miljökemi;

   Abstract : Persistent organic pollutants (POPs) is a group of chemicals that are toxic, undergo long-range transport and accumulate in biota. Due to their persistency the distribution and recirculation in the environment often continues for a long period of time. READ MORE

5. 18. Developmental Neurotoxicity of Environmental Pollutants : Effects on neuronal protein markers after neonatal exposure

   Author : Iwa Lee; Henrik Viberg; Elena Jazin; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental neurotoxicity; Neonatal exposure; Protein markers; Environmental pollutants; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

   Abstract : This thesis focused on investigations of the developmental neurotoxic effects of bisphenol A (BPA) or perfluorohexane sulfonate (PFHxS), after a single neonatal exposure, during a critical period of the brain development in mice.BPA is a well-known industrial chemical used in the production of polymer products and PFHxS is used as an industrial additive as a surfactant.

7. 20. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities : Removal, fate and environmental impact

   Author : Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; analytisk kemi; Analytical Chemistry;

   Abstract : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.
