Degradation of a persistent organic pollutant perfluorooctane sulphonate with Ti/SnO2–Sb2O5/PbO2-PTFE anode

Perfluorooctane sulphonate and perfluorooctanoic acid in drinking and environmental waters.

Perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) are chemicals that have been used for many years as surfactants in a variety of industrial and consumer products. Owing to their persistent, bioaccumulative and toxic (PBT) characteristics, PFOS has been phased out by its principal producer and the use of PFOA has been reduced. This PBT potential and a number of pollution incid...

Geographic Differences in Persistent Organic Pollutant Levels of Yellowfin Tuna

BACKGROUND Fish are a source of persistent organic pollutants (POPs) in the human diet. Although species, trophic level, and means of production are typically considered in predicting fish pollutant load, and thus recommendations of consumption, capture location is usually not accounted for. OBJECTIVES Yellowfin tuna (Thunnus albacares) are harvested from across the world's oceans and are wid...

Persistent Organic Pollutant Exposure Leads to Insulin Resistance Syndrome

BACKGROUND The incidence of the insulin resistance syndrome has increased at an alarming rate worldwide, creating a serious challenge to public health care in the 21st century. Recently, epidemiological studies have associated the prevalence of type 2 diabetes with elevated body burdens of persistent organic pollutants (POPs). However, experimental evidence demonstrating a causal link between P...

Perovskite-structured CaTiO3 coupled with g-C3N4 as a heterojunction photocatalyst for organic pollutant degradation

A novel graphitic carbon nitride (g-C3N4)-CaTiO3 (CTCN) organic-inorganic heterojunction photocatalyst was synthesized by a facile mixing method, resulting in the deposition of CaTiO3 (CT) nanoflakes onto the surface of g-C3N4 nanosheets. The photocatalytic activity of the as-synthesized heterojunction (along with the controls) was evaluated by studying the degradation of an aqueous solution of...
