Abstract. European scale harmonized monitoring of atmospheric composition was initiated in the early 1970s, and activity has generated a comprehensive dataset (available at http://www.emep.int) which allows evaluation regional spatial trends air pollution during period nearly 40 yr. Results from made within EMEP, Monitoring Evaluation Programme, show large reductions ambient concentrations deposition sulphur species last decades. Reductions are order 70–90% since year 1980, correspond well...
This paper presents data from a survey of polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) concentrations in 191 global background surface (0−5 cm) soils. Differences up to 4 orders magnitude were found between sites for PCBs. The lowest highest PCB (26 97 000 pg/g dw) samples Greenland mainland Europe (France, Germany, Poland), respectively. Background soil strongly influenced by proximity source region organic matter (SOM) content. Most (>80%) the estimated burden remains...
The first spatially and temporally resolved inventory of BDE28, 47, 99, 153, 183, 209 in the anthroposphere environment is presented here. stock emissions PBDE congeners were estimated using a dynamic substance flow analysis model, CiP-CAFE. To evaluate our results, emission estimates used as input to BETR-Global model. Estimated concentrations compared with observed air from background areas. global (a) in-use (b) waste stocks ∑5BDE(28, 183) BDE209 are be ∼25 400 kt 13 100 kt, respectively,...
Temporal trends of Persistent Organic Pollutants (POPs) measured in Arctic air are essential understanding long-range transport to remote regions and evaluate the effectiveness national international chemical control initiatives, such as Stockholm Convention (SC) on POPs. Long-term monitoring POPs is conducted under Monitoring Assessment Programme (AMAP) at four stations: Alert, Canada; Stórhöfði, Iceland; Zeppelin, Svalbard; Pallas, Finland, since 1990s using high volume samplers. observed...
The transport of discarded electronic and electrical appliances (e-waste) to developing regions has received considerable attention, but it is difficult assess the significance this issue without a quantitative understanding amounts involved. main objective study track global e-wastes by compiling constraining existing estimates amount e-waste generated domestically in each country MGEN, exported from countries belonging Organization for Economic Cooperation Development (OECD) MEXP, imported...
Surface soils (0−5 cm) from remote/rural woodland (coniferous and deciduous) grassland locations on a latitudinal transect through the United Kingdom Norway were analyzed for polybrominated diphenyl ethers (PBDEs). Concentrations ranged between 65 12 000 ∑ALLPBDE ng kg-1 dry weight. PBDE-47, -99, -100, -153, -154the major constituents of penta-BDE technical productdominated average congener pattern soils. Indeed, composition distribution measured in these European background closely matched...
Elevated concentrations of various industrial-use Persistent Organic Pollutants (POPs), such as polychlorinated biphenyls (PCBs), have been reported in some developing areas subtropical and tropical regions known to be destinations e-waste. We used a recent inventory the global generation exports e-waste develop scale emission scenarios for organic contaminants (IUOCs). For representative IUOCs (RIUOCs), only hypothetical emissions via passive volatilization from were considered whereas...
Abstract. Passive air samplers (PAS) were deployed at 86 European background sites during summer 2006 in order (i) to gain further insight into spatial patterns of persistent organic pollutants (POPs) and, (ii) evaluate PAS as an alternative sampling technique under EMEP (Co-operative programme for monitoring and evaluation the long-range transmissions Europe). The samples analyzed selected PCBs, HCHs, DDTs, HCB, PAHs chlordanes, concentrations calculated on basis losses performance...
Cyclic volatile methyl siloxanes (cVMS) are present in technical applications and personal care products. They predicted to undergo long-range atmospheric transport, but measurements of cVMS remote areas remain scarce. An active air sampling method for decamethylcyclopentasiloxane (D5) was further evaluated include hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), dodecamethylcyclohexasiloxane (D6). Air samples were collected at the Zeppelin observatory Arctic (79° N, 12°...
Abstract. A first long-term monitoring of selected persistent organic pollutants (POPs) in Antarctic air has been conducted at the Norwegian research station Troll (Dronning Maud Land). As target contaminants 32 PCB congeners, α- and γ-hexachlorocyclohexane (HCH), trans- cis-chlordane, cis-nonachlor, p,p'- o,p-DDT, DDD, DDE as well hexachlorobenzene (HCB) were selected. The program with weekly samples taken during period 2007–2010 was coordinated parallel Arctic site (Zeppelin mountain,...
The long-term time trends of atmospheric pollutants at eight Arctic monitoring stations are reported. work was conducted under the Monitoring and Assessment Programme (AMAP) Council. were: Alert, Canada; Zeppelin, Svalbard; Stórhöfði, Iceland; Pallas, Finland; Andøya, Norway; Villum Research Station, Greenland; Tiksi Amderma, Russia. Persistent organic (POPs) such as α- γ-hexachlorocyclohexane (HCH), polychlorinated biphenyls (PCBs), α-endosulfan, chlordane, dichlorodiphenyltrichloroethane...
Organic contaminants (polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and chlorinated paraffins (CPs)) heavy metals metalloids (Ag, Cd, Co, Cr, Cu, Hg, Ni, Pb, Sb, Zn) were analysed in surface soil samples from the Agbogbloshie e-waste processing dumping site Accra (Ghana). In order to identify which of pollutants are likely be linked specifically handling e-waste, also collected Kingtom general waste Freetown (Sierra Leone)....
Informal e-waste recycling activities have been shown to be a major emitter of organic flame retardants (FRs), contributing both environmental and human exposure laborers at sites in some West African countries, as well China India. The main objective this study was determine the levels selected FRs air soil samples collected from areas with intensive informal Karachi, Pakistan. Dechlorane Plus (DP) "novel" brominated (NBFRs) were often detected high concentrations soils, while...
Abstract. The Zeppelin Observatory (78.90∘ N, 11.88∘ E) is located on Mountain at 472 m a.s.l. Spitsbergen, the largest island of Svalbard archipelago. Established in 1989, observatory part Ny-Ålesund Research Station and an important atmospheric measurement site, one only a few high Arctic, several European global monitoring programmes research infrastructures, notably Monitoring Evaluation Programme (EMEP); Arctic Assessment (AMAP); Global Atmosphere Watch (GAW); Aerosol, Clouds Trace...
As of 2020, a cumulative total 31 306 kilotonnes manmade persistent organic pollutants had been synthesized and commercialized worldwide, resulting in releases 20 348 into the global environment.
