Monitoring data are necessary for the future production of engineered nanomaterials and development regulations nanomaterials. Therefore, it is to develop methods that reliably detect quantify in real-world systems at expectedly low concentrations. In this work we tested several methodological approaches titanium dioxide released from sunscreen products into Old Danube Lake (Vienna, Austria), which heavily used recreational activities like bathing water sports during summer season. During a...
Visualize printing all 24 volumes of the Encyclopaedia Britannica on head a pin. In 1959, Richard Feynman articulated this reality in an insightful address at annual meeting American Physical Society. what became prophetic speech, “There's plenty room bottom” 1, discussed manipulating and controlling matter small scale. Back then, forward thinking conjured images going to moon era when computers occupied entire floors buildings. Fifty years later, we no longer have imagine. We are actively...
The production and use of nanoparticles leads to the emission manufactured or engineered into environment. Those particles undergo many possible reactions interactions in environment they are exposed to. These resulting behavior fate have been studied for decades through naturally occurring nanoparticulate (1-100 nm) colloidal (1-1000 substances. knowledge gained from these investigations is nowhere near sufficiently complete create a detailed model environment, but valuable starting point...
Microplastics (MPs) have been identified as contaminants of emerging concern in aquatic environments and research into their behavior fate has sharply increasing recent years. Nevertheless, significant gaps remain our understanding several crucial aspects MP exposure risk assessment, including the quantification emissions, dominant processes, types analytical tools required for characterization monitoring, adequate laboratory protocols analysis hazard testing. This Feature aims at...
Industry has already commenced the large-scale production of some nanomaterials. Evidence for toxic effects engineered nanoparticles (ENP) on model organisms is increasing. However, in order to assess consequences environmental hazards, a better understanding required behavior ENP aquatic ecosystems and their impact complex communities. In this research, through experimenting with different TiO2 stream microcosms, we have shown that microbial membranes were significantly compromised, even...

Engineered nanoparticles (ENPs) from industrial applications and consumer products are already being released into the environment. Their distribution within environment is, among other factors, determined by dispersion state aggregation behavior of and, in turn, directly affects exposure aquatic organisms to EPNs. The (or colloidal stability) these particles is controlled water chemistry a large extent, surface particles. This paper presents results extensive stability tests on commercially...
This perspective demonstrates the inapplicability of equilibrium partition coefficients as fate descriptors for nanoparticles.
This novel single-particle multi-element fingerprinting (spMEF) method makes it possible to discriminate engineered and natural nanoparticles in complex matrices.
Riverine transport of iron (Fe) and arsenic (As) is affected by their associations with natural organic matter (NOM) suspended (oxy)hydroxides. Speciation has a strong influence on element from the headwaters to ocean because NOM may be transported over longer distances compared We show that Fe speciation changes along flow path boreal watercourse, as water moves NOM-rich, acidic first-order streams pH low 3.9 less higher-order systems (up 6.4).

Field-Flow Fractionation (FFF) is now recognised as a versatile pool of techniques allowing particle size or molar mass to be obtained in wide variety samples covering numerous applications the fields environment, materials biology. In same time, Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) has an indisputable place field elemental detectors and coupling between FFF ICP-MS can considered emerging technique capable reach relevant physico-chemical information at sub-micrometre scale...
Bringing together topic-related European Union (EU)-funded projects, the so-called “NanoSafety Cluster” aims at identifying key areas for further research on risk assessment procedures nanomaterials (NM). The outcome of NanoSafety Cluster Working Group 10, this commentary presents a vision concern-driven integrated approaches (eco-)toxicological testing and (IATA) NM. Such should start out by determining concerns, i.e., specific information needs given NM based realistic exposure scenarios....
Validation of modeled environmental concentrations nanomaterials is currently not possible.
Environmental context The detection and characterisation of engineered nanomaterials in the environment is essential for exposure risk assessment this emerging class materials. However, ubiquitous presence naturally occurring presents a unique challenge accurate determination environmental matrices. New techniques methodologies are being developed to overcome some these issues by taking advantage subtle differences elemental isotopic ratios within nanomaterials. Abstract increasing...
