Systematic description of more than 200 uses PFAS and the individual substances associated with each them (over 1400 in total).
Phthalic acid esters (phthalates) are used as plasticizers in numerous consumer products, commodities, and building materials. Consequently, phthalates found human residential occupational environments high concentrations, both air dust. Phthalates also ubiquitous food environmental contaminants. An increasing number of studies sampling urine reveal the phthalate exposure consumers industrialized countries. At same time, recent toxicological have demonstrated potential most important to...
Perfluorinated compounds have been used for more than 50 years as process aids, surfactants, and surface protection. This study is a comprehensive assessment of consumer exposure to perfluorooctane sulfonate (PFOS) perfluorooctanoic acid (PFOA) from variety environmental product-related sources. To identify relevant pathways leading PFOS PFOA scenario-based approach has applied. Scenarios represent realistic situations where age- gender-specific occurs in the everyday life consumers. We find...
For a proactive risk assessment of engineered nanoparticles (ENPs) it is imperative to derive predicted environmental concentration (PEC) values for ENPs in different compartments; PECs can then be compared effect thresholds. From the basis established multimedia fate models organic pollutants, we develop new concept modeling with process descriptions based on specific properties ENPs. Our framework highly flexible and adjusted various settings. As first case study, transport TiO(2) NPs...
While per- and polyfluoroalkyl substances (PFAS) are a class of synthetic organic with diverse structures, properties, uses, bioaccumulation potentials toxicities, nearly all PFAS highly persistent.
Fluoropolymers are a group of polymers within the class per- and polyfluoroalkyl substances (PFAS). The objective this analysis is to evaluate evidence regarding environmental human health impacts fluoropolymers throughout their life cycle(s). Production some intimately linked use emissions legacy novel PFAS as polymer processing aids. There serious concerns toxicity adverse effects fluorinated aids on humans environment. A variety other PFAS, including monomers oligomers, emitted during...
Environmental contextPoly- and perfluorinated alkyl substances (PFASs) include a wide range of individual compounds that are used in many consumer products, but only few physicochemical property data available for these chemicals. Here we provide estimates properties (vapour pressure, water solubility, etc.) 130 PFASs derived with quantum-chemical model. Our results insight into the effect molecular structure on basis estimating environmental partitioning fate PFASs. AbstractRecently, there...
Grouping strategies are needed for per- and polyfluoroalkyl substances (PFAS), in part, because it would be time resource intensive to test evaluate the more than 4700 PFAS on global market a chemical-by-chemical basis.
Engineered nanomaterials (ENMs) are increasingly entering the environment with uncertain consequences including potential ecological effects.Various research communities view differently whether ecotoxicological testing of ENMs should be conducted using environmentally relevant concentrations-where observing outcomes is difficult-versus higher ENM doses, where responses observable.What exposure conditions typically used in assessing hazards to populations?What test ecosystem-scale...
In this discussion paper, the transition from long-chain poly- and perfluorinated alkyl substances (PFASs) to fluorinated alternatives is addressed. Long-chain PFASs include perfluoroalkyl carboxylic acids (PFCAs) with 7 or more carbons, sulfonic (PFSAs) 6 their precursors. Because have been found be persistent, bioaccumulative toxic, they are being replaced by a wide range of alternatives. We summarize key concerns about potential impacts on human health environment in order provide concise...
Abstract Food packaging is of high societal value because it conserves and protects food, makes food transportable conveys information to consumers. It also relevant for marketing, which economic significance. Other types contact articles, such as storage containers, processing equipment filling lines, are important production supply. articles made up one or multiple different materials consist chemicals. However, chemicals transfer from all into and, consequently, taken by humans. Here we...
The concept of essential use is developed and applied to various uses PFASs determine the feasibility elimination or substitution in each category.
Fourteen organophosphate esters (OPEs) were measured in the filter fraction of 117 active air samples from yearly ship-based sampling campaigns (2007–2013) and two land-based stations Canadian Arctic, to assess trends long-range transport potential OPEs. Four OPEs detected up 97% samples, seven 50% or less three not detected. Median concentrations ∑OPEs 237 50 pg m–3 for ship- respectively. Individual median ranged below detection 119 ethanol, 2-chloro-, phosphate (3:1) (TCEP). High 2340...
Persistence is a hazard criterion for chemicals enshrined in chemical regulation worldwide. In this paper, we argue that the higher persistence of chemical, greater emphasis it should be given assessment and decision making. We provide case studies three classes highly persistent (chlorofluorocarbons, polychlorinated biphenyls, per- polyfluoroalkyl substances) to exemplify problems unique chemicals, despite their otherwise diverse properties. Many well-known historical pollution were result...
Per- and polyfluoroalkyl substances (PFAS) are of concern because their high persistence (or that degradation products) impacts on human environmental health known or can be deduced from some well-studied PFAS. Currently, many different PFAS (on the order several thousands) used in a wide range applications, there is no comprehensive source information individual functions applications. Here we provide broad overview use categories where have been employed for which function; also specify...
