Environmental contextIncreasing global plastic production adds debris to the environment. We show that potentially harmful additives present in particles are released water at an increased rate when material properties change by aging due exposure high temperature and especially UV radiation. For risk assessment of such additives, more information on their degradation products toxicity is needed. AbstractRecycled granules high-density polyethylene, polyvinyl chloride polystyrene size...
Here, we report a comparative study of different sum parameter analysis methods for the extraction per- and polyfluoroalkyl substances (PFAS) from manufactured consumer products, which can be measured by combustion ion chromatography (CIC). Therefore, hydrolysis-based method was further developed, accounts addition hydrolyzable covalently bound polyfluoroalkylated side-chain polymers (SFPs) to extractable organic fluorine portion mass balance proposed as "hydrolyzable organically fluorine"...
In this study, soil top layers from the German Environmental Specimen Bank (ESB) covering a period 2002 to 2018 and 11 sampling sites representing four ecosystem types were analysed for 24 PFAS (11 PFCA, 7 PFSA, 6 precursors), including total oxidizable precursor (TOP) assay. Median ΣPFAS levels before after TOP assay ranged 0.31 19.7 μg/kg dry weight (dw) 0.32 20.4 dw, respectively. The most frequently measured above LOQ PFOS PFOA, which present at concentrations 0.1 dw in each sample. Both...
The chemical burden on the environment and human population is increasing. Consequently, regulatory risk assessment must keep pace to manage, reduce, prevent adverse impacts environmental health associated with hazardous chemicals. Surveillance of chemicals known, emerging, or potential future concern, entering environment-food-human continuum needed document reality risks posed by ecosystem from a one perspective, feed into early warning systems support public policies for exposure...
One of the major challenges effect-directed identification hazardous chemicals in sediments is appropriate consideration bioavailability for a hazard-based prioritization fractions and toxicants. The equilibrium partitioning approach frequently used to estimate sediment contaminants. To simulate ofthe constituents complex contaminations sediment-water-biota system, new dosing technique based on silicone elastomer stirrer bars (silicone rods) use growth inhibition test with green algae...
The German Environmental Survey for Children and Adolescents 2014-2017 (GerES V) investigated the current internal exposure to polychlorinated biphenyls (PCB) organochlorine pesticides (OCP). These analyses were carried out a population-representative sub-sample of 1135 children adolescents (aged 3-17 years) all 2394 GerES V participants. Blood plasma samples analyzed seven indicator PCB (PCB 28, 52, 101, 118, 138, 153 180) selected OCP (hexachlorobenzene, three hexachlorocyclohexane...
Abstract Over the past decades, thousands of different per- and polyfluoroalkyl substances (PFASs) have been produced applied in various industrial processes consumer products. Their structural diversity has reached a level that cannot be covered by classical target screening methods for individual compounds. Large-scale contaminations soil, however, require need to adapt new analytical can describe contamination more comprehensively. While sum parameters such as total oxidisable precursor...
Effect-directed analysis (EDA) has been frequently and successfully used to identify key toxicants in sediment extracts. However, by disregarding bioavailability this approach may lead a biased prioritisation of fractions with respect hazards risks. To overcome problem the present EDA components from Bílina river (Most, Czech Republic), that inhibit growth green algae Scenedesmus vacuolatus, applies novel partition-based dosing technique prioritize major toxic compounds comparison...
A laboratory biofilm consisting of the phototrophic cyanobacterium Nostoc punctiforme ATCC 29133 and rock-inhabiting ascomycete Knufia petricola CBS 726.95 was tested for its mineral weathering potential. Minerals with different grain sizes mineralogy were incubated without in batch flow-through column experiments. After incubation, dissolution quantified analysing (i) leachate chemistry via ICP-OES/MS (inductively coupled plasma optical emission spectrometry/mass spectrometry) (ii) residual...
Anticipation is an important performance factor in karate kumite. A new approach analysing anticipation realistic combat situations by motion capturing with a high temporal resolution presented. The advantage of this that both athletes interacting sports specific can be recorded synchronously; thus, the presented method has potential to analyse visual information pickup due coordination pattern interaction between real athletes. aim demonstrate usability current for research and investigate...
Abstract Titanium dioxide nanoparticles (nTiO 2 ) form reactive oxygen species (ROS) under irradiation by ultraviolet light (UV). This known photocatalytic activity may finally affect the presence and toxicity of organic environmental chemicals, which have not yet been studied at ambient UV intensity. The authors used a three‐factorial design to evaluate interaction carbamate insecticide pirimicarb (initial nominal concentration, 20 µg/L), (40 W/m for 15 min), nTiO (∼100 nm; 2.0 mg/L)....
Abstract This article discusses the development and application of virtual environments (VEs) in domain exercise as well research recreational high-performance sports. A special focus is put on use characters (VCs). For its elaboration, following criteria parameters were chosen: scene content role VC, output device, kind additional feedback, level expertise tested participants, user’s movement (reaction), visualization body, study evaluation. We explored VCs embodying opponents, teammates,...
Sub-aerial biofilms (SAB) are ubiquitous, self-sufficient microbial ecosystems found on mineral surfaces at all altitudes and latitudes. SABs, which the principal causes of weathering exposed terrestrial surfaces, characterised by patchy growth dominated associations algae, cyanobacteria, fungi heterotrophic bacteria. A recently developed in vitro system to study colonisation rocks air included two key SAB participants - rock-inhabiting ascomycete Knufia petricola (CBS 123872) phototrophic...
