Sonochemical degradation of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in groundwater: kinetic effects of matrix inorganics.
Ultrasonic irradiation has been shown to effectively degrade perfluorinated chemicals (PFCs) such as perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in aqueous solution. Reduced PFC sonochemical degradation rates in organic-rich groundwater taken from beneath a landfill, however, testify to the negative kinetic effects of the organic groundwater constituents. In this study, the P...
متن کاملImmunohepatotoxicity of the persistent environmental pollutants perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS)
Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), manufactured for a variety of industrial and consumer applications, are ubiquitous environmental pollutants. Their accumulation in humans and wildlife raises serious health concerns. Here, we examined the potential effects of PFOA and PFOS on the innate immune system in mice. Short-term dietary exposure to high doses reduces the to...
متن کاملSerum Perfluorooctanoate (PFOA) and Perfluorooctane Sulfonate (PFOS) Concentrations and Liver Function Biomarkers in a Population with Elevated PFOA Exposure
BACKGROUND Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) persist in the environment and are found in relatively high concentrations in animal livers. Studies in humans have reported inconsistent associations between PFOA and liver enzymes. OBJECTIVES We examined the cross-sectional association between serum PFOA and PFOS concentrations with markers of liver function in adults...
متن کاملCord Serum Concentrations of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoate (PFOA) in Relation to Weight and Size at Birth
BACKGROUND Recent studies have reported developmental toxicity among rodents dosed with perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA). OBJECTIVES We examined the relationship between concentrations of PFOS and PFOA in cord serum (surrogates for in utero exposures) and gestational age, birth weight, and birth size in humans. METHODS We conducted a hospital-based cross-sectio...
متن کاملPerfluorooctanoate and perfluorooctane sulfonate concentrations in surface water in Japan.
Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) are synthetic surfactants used in Japan. An epidemiological study of workers exposed to PFOA revealed a significant increase in prostate cancer mortality. A cross-sectional study of PFOA-exposed workers showed that PFOA perturbs sex hormone homeostasis. We analyzed their concentrations in surface water samples collected from all ove...
