The environmental safety of decabromodiphenyl ether (BDE-209), a widely used flame retardant, has been the topic controversial discussions during past several years. Degradation BDE-209 into lower brominated diphenyl congeners, exhibiting higher bioaccumulation potential, critical issue. Here, we report on degradation and formation octa- nonabromodiphenyl congeners under anaerobic conditions. Sewage sludge collected from mesophilic digester was as inoculum incubated up to 238 days with...
UV filters are widely used compounds in many personal care products and cosmetics, such as sunscreens. After use, washed off from skin clothes enter the aquatic environment. Recent studies indicate that some lipophilic do accumulate biota act endocrine disruptors. In this study, concentrations of 4-MBC (4-methylbenzylidene camphor) OC (octocrylene), two filters, were determined muscle tissue fish (brown trout, Salmo trutta fario) seven small Swiss rivers, all receiving inputs wastewater...
In this study, the hypothesis that melting Alpine glaciers may represent a secondary source of persistent organic chemicals is investigated. To end, dated sediment core from glacier-fed lake (Lake Oberaar, Switzerland) was analyzed for wide range pollutants, organochlorine pesticides, and synthetic musk fragrances. Input fluxes all organochlorines increased in 1950s, peaked 1960s-1970s, decreased again to low levels 1980s-1990s. This observation reflects emission history these compounds...
In October 2000, joint sealants containing polychlorinated biphenyls (PCB) were discovered in various public buildings Switzerland. Triggered by this event, a nationwide comprehensive study was initiated the Swiss Agency for Environment, Forests, and Landscape, 1348 samples of as well 160 indoor air from concrete erected between 1950 1980 analyzed. Out samples, 646 (48%) contained PCB. 279 (21%) PCB concentrations 10 g/kg more detected, 100 or found 129 (9.6%) samples. These data indicate...
A dated sediment core from Lake Thun covering the last 120 years was analyzed to get an overview of historical trend chlorinated paraffin (CP) and polychlorinated biphenyl (PCB) deposition, because CPs PCBs have/had similar applications as plasticizers flame retardants. Total CP concentrations (sum short chain (SCCP), medium (MCCP), long (LCCP)) showed a steep increase in 1980s more-or-less stable level 50 ng g−1 dry weight (dw) since then. The concentration-time profile is good agreement...
Urban water management requires further clarification about pollutants in storm water. Little is known the release of organic additives used construction materials and impact these compounds to runoff. We investigated sources pathways materials, i.e., biocides facades' render as well root protection products bitumen membranes for rooftops. Under wet-weather conditions, concentrations diuron, terbutryn, carbendazim, irgarol®1051 (all from facades) mecoprop receiving exceeded predicted...
Diesel particulate filters (DPFs) are a promising technology to detoxify diesel exhaust. However, the secondary combustion of soot and associated compounds may also induce formation new pollutants. is rated as carcinogenic humans acts carrier for variety genotoxic such certain polycyclic aromatic hydrocarbons (PAHs) or nitrated PAHs (nitro-PAHs). Furthermore, exhaust contains considerable amounts nitric oxide (NO), which can be converted more powerful nitrating species like nitrogen dioxide...
With the recent ban of pentabromodiphenyl ether (technical PentaBDE) and octabromodiphenyl OctaBDE) mixtures in European Union (EU) parts United States, decabromodiphenyl DecaBDE) remains as only polybrominated diphenyl (PBDE) based flame retardant available, today. The EU risk assessment report for DecaBDE identified a high level uncertainty associated with suitability current approach secondary poisoning by debromination to toxic lower brominated diphenylethers. Addressing this still open...

After atmospheric deposition and storage in the ice, glaciers are temporary reservoirs of persistent organic pollutants (POPs). Recently, hypothesis that melting represent secondary sources these has been introduced by investigations historical trend POPs a dated sediment core from proglacial Alpine Lake Oberaar. Here, is further confirmed comparison data gathered two lakes with glaciated nonglaciated hydrological catchment. The (Lake Engstlen Stein Bernese Alps Switzerland) situated only 8...
Short-chain chlorinated paraffins (SCCPs) are of concern due to their potential for adverse health effects, bioaccumulation, persistence, and long-range transport. Data on concentrations SCCPs in urban areas underlying emissions still scarce. In this study, we investigated the levels spatial distribution air, based two separate, spatially resolved sampling campaigns city Zurich, Switzerland. SCCP air ranged from 1.8 17 ng·m–3 (spring 2011) 1.1 42 2013) with medians 4.3 2.7 ng·m–3,...
There is increasing concern about diffuse pollution of aquatic systems by biocides used in urban areas. We investigated sources and pathways significant for the storm water runoff. Main seem to be building envelopes, i.e. facades (paints, plasters) roof sealing membranes. First results from a defined catchment drained separated sewer system without any agricultural activities reveal substantial occurrence. Even after first flush, concentrations terbutryn, carbendazim, mecoprop as well...
Abstract Atmospheric particulate matter (PM1) was collected at an urban and a rural site in Switzerland during hibernal high air pollution episode investigated for estrogenicity using estrogen‐sensitive reporter gene assay (ER‐CALUX). All samples that were tested induced estrogen receptor‐mediated expression T47D human breast adenocarcinoma cells. Observed estrogenic activities corresponded to 17 β ‐estradiol (E2) CALUX equivalent concentrations ranging from 2 23 ng E2‐CEQ per gram of PM1...
Compost and digestate are important recycling fertilizers have beneficial effects on soil parameters. However, they can contain significant amounts of organic pollutants. Here, the first comprehensive data set dibenzo-p-dioxins -furans (PCDD/F), dioxin-like polychlorinated biphenyls (DL-PCB), brominated flame retardants, perfluorinated alkyl substances (PFAS), pesticides, phthalates, nonylphenol chlorinated paraffins (CP) in source-separated compost from Switzerland is presented (n = 3–18)....
Chronology of brominated fame retardants (BFRs), a class currently widely used chemicals, was compared to the respective historical profiles legacy organochlorine compounds in three dated sediment cores from prealpine lake (Lake Thun, Switzerland). Concentrations polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) started increase 1980s−1990s. In more recent layers, PBDEs still had steady or increasing concentrations, whereas for HBCDs one core revealed decreasing...
