PFOA and PFOS have been the most extensively produced and studied of these chemicals.

  • Perfluorinated compounds in landfill leachate and

    Perfluorinated compounds (PFCs) are a class of persistent organic pollutants (POPs) with potential major health and environmental concerns. PFCs are thermally and chemically stable, and do not readily degrade in the environment. PFCs have been detected in numerous environmental matrices, including surface water, ground water and sediment. PFCs are used for surface treatments for paper and ...

    Recent efforts have been directed towards the design of efficient and contaminant selective remediation technology for the removal of perfluorinated compounds (PFCs) from soils, sediments, and aquatic environments. While there is a general consensus on adsorption-based processes as the most suitable methodology for the removal of PFCs from aquatic environments, challenges exist regarding the ...

    Environmental context Five years ago a well-cited review of the sources and fate of perfluorinated carboxylates was published. The findings of that review are revisited here in light of recently published measurement and modelling studies of the sources and fate of these compounds, and an attempt is made to reconcile the many seemingly disparate findings reported. This review also aims to ...

  • Phase shift colloids as ultrasound contrast agents -

    Agents for enhancing the contrast in a diagnostic ultrasound procedure comprise colloidal dispersions of the liquid-in-liquid type, i.e., emulsions or microemulsions, in which the dispersed liquid phase is a liquid having a boiling point below the temperature of the animal to be imaged and which therefore undergoes a phase change from a dispersed liquid to a highly echogenic dispersed gaseous ...
