The primary aim of this article is to provide an overview of perfluoroalkyl and polyfluoroalkyl substances (PFASs) detected in the environment, wildlife, and humans, and recommend clear, specific, and descriptive terminology, names, and acronyms for PFASs. The overarching objective is to unify and harmonize communication on PFASs by offering terminology for(More)
Polychlorinated biphenyls (PCBs) are persistent pollutants that are ubiquitous in the food chain, and detectable amounts are in the blood of almost every person in most populations that have been examined. Extensive evidence from animal studies shows that PCBs are neurotoxins, even at low doses. Interpretation of human data regarding low-level, early-life(More)
BACKGROUND Perfluoroalkyl acids (PFAAs) are found globally in wildlife and humans and are suspected to act as endocrine disruptors. There are no previous reports of PFAA levels in adult men from Denmark or of a possible association between semen quality and PFAA exposure. OBJECTIVES We investigated possible associations between PFAAs and testicular(More)
In recent years, polyfluorinated chemicals (PFCs) have increasingly been used as surfactants in various industry- and consumer products, because of their unique properties as repellents of dirt, water and oils. The most well-known PFCs are perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and their derivatives belonging to the group of(More)
Persistent and toxic chemicals such as polychlorinated biphenyls, dibenzo-p-dioxins and dibenzofurans are able to accumulate in human tissues, especially in fats. In recent years PCBs have frequently been detected in human milk, blood and adipose tissue from the general population and levels in different tissues correspond to the fat content of the samples.(More)
BACKGROUND, AIM AND SCOPE Glass wools are man-made vitreous fibres, which consist principally of sodium, calcium and magnesium silicates, but may contain smaller amounts of other elements, including boron. The boron contents originate from the use of borates in the glass melting process as a glass former and a flux agent. During the production and(More)
The aim of this work was to investigate the effect on starch molecular and physicochemical properties of down regulation of the R1 protein in potato (Solanum tuberosum L. cv. "Dianella") tubers. Most prominent is a 90% suppression of the phosphate content in the isolated potato tuber starch. The amylopectin chain length distribution profile as determined by(More)
Insulation of buildings in order to save heating energy is an important technology for enabling sustainable development. This paper summarises the results of a comparative LCA study according to ISO 14040 standard series of HT stone wool, flax representing crop grown products and paper wool representing recycled products applied for roof insulation. As the(More)
Polychlorinated terphenyls (PCTs) have almost identical characteristics to high chlorinated PCBs: extremely stable, bioaccumulable and biomagnification through food webs might take place. PCT is especially used in investment casting waxes and as a substitute for PCB. In spite of the limited use until now, PCT has been detected in a great variety of(More)
