Interest and concern about polyfluorinated compounds (PFCs), such as perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and an increasing number of other related compounds is growing as more is learned about these ubiquitous anthropogenic substances. Many of these compounds can be toxic, and they are regularly found in the blood of animals and humans worldwide. A great deal of research has been conducted in this area, but a surprising amount remains unknown about their…

Perfluorooctanoic Acid (PFOA): Environmental Sources, Chemistry, Toxicology, and Potential Risks

Alterations in industrial manufacturing processes, increased regulatory scrutiny, and advanced water treatment options have reduced the reported human body burden of PFAS in the U.S., including for PFOA.

Per- and Polyfluoroalkyl Substances: An Emerging Contaminant of Concern

This chapter describes a large number of PFAS studies in blood and harmful health effects in people, and explains health advisory levels, minimal risk levels, and medical testing and medical management.

– Per-and polyfluoroalkyl substances ( PFASs ) July 2016

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are used in various consumer and industrial products, including food contact materials (FCMs) (Figure 1). Thousands of different PFASs have been

Per- and Polyfluoroalkyl Substances

Perand polyfluoroalkyl substances (PFAS), also commonly referred to as perfluorinated chemicals or PFCs, are a group of anthropogenic chemicals with past and current uses in industrial processes and

Adverse Effects of Perfluorooctane Sulfonate on the Liver and Relevant Mechanisms

Perfluorooctane sulfonate (PFOS) is a persistent, widely present organic pollutant. PFOS can enter the human body through drinking water, ingestion of food, contact with utensils containing PFOS, and

Perfluorinated Compounds: An Overview

Materials presented in this volume should provide a scientific basis to inform the design of safe replacement products for the current crop of perfluorinated chemicals that promises to be less persistent and prevalent in the environment.

Analysis of perfluoroalkyl substances in food and evironmental matrices

Per- and poly- fluoroalkyl substances (PFASs) are a group of manmade substances synthesised for more than 60 years. Due to their specific properties, PFASs have been widely used for industrial

Determination of perfluorinated compounds in the upper Mississippi river basin.

An existing method was improved and applied in a large-scale evaluation of the Upper Mississippi River Basin, one of the largest watersheds in the world, suggesting various point source inputs within the Basin.

Perfluoroalkyl contaminants in a food web from Lake Ontario.

It was shown that bioaccumulation was indeed occurring at the top of the food web for all perfluoroalkyl compounds except PFOA, and future monitoring at other locations in Lake Ontario, and in other aquatic environments, is necessary to determine if these food web dynamics are widespread.

The aim of the present study was to determine whether a statistically significant, concentration-dependent carryover of PFOA and PFOS in crop plants can take place, which would provide a potential entrance point for these substances into the food chain.

Are PFCAs bioaccumulative? A critical review and comparison with regulatory criteria and persistent lipophilic compounds.

The bioaccumulation potential of perfluorinated acids with seven fluorinated carbons or less appears to be several orders of magnitude lower than "legacy" persistent lipophilic compounds classified as bioaccuulative.
