1. Environmental occurrence and fate of semifluorinated n-alkanes and perfluorinated alkyl acids present in ski waxes
Abstract : Highly fluorinated organic compounds are emerging environmental contaminants of concern, due to their persistence, ubiquitous distribution, bioaccumulation potential and toxicity. Ski waxes are sources of highly fluorinated chemicals to the environment that have not been investigated so far. READ MORE

2. Sources, transport and fate of perfluoroalkyl acids in the atmosphere
Abstract : Perfluoroalkyl acids (PFAAs) are man-made chemicals which have been observed in the global environment, even in locations far away from where they are emitted. These persistent substances are taken up in humans and biota and may have toxic effects. READ MORE

3. Enrichment of biogenic and anthropogenic organic substances on sea spray aerosols
Abstract : The world’s oceans are the source of one of the most abundant types of natural aerosols, namely sea spray aerosols (SSA). By scattering solar radiation, SSA play a significant role in controlling the Earth’s radiation budget, while they are also involved in the formation of clouds, acting as cloud condensation nuclei (CCN).

4. Analysis of Perfluoroalkyl Acids in Swedish Biota : Temporal trends, tissue distribution and toxicity
Abstract : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. READ MORE

5. Analysis and human levels of persistent perfluorinated chemicals
Abstract : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. READ MORE
