Abstract:
... Anthropogenic emissions of the toxic heavy metal mercury (Hg) have substantially increased atmospheric Hg levels during the 20th century compared to preindustrial times. However, on a regional scale, atmospheric Hg concentration or deposition trends vary to such an extent during the industrial period that the consequences of recent Asian emissions on atmospheric Hg levels are still unclear. Here w ...

Abstract:
... More than 3000 per- and polyfluoroalkyl substances (PFASs) are, or have been, on the global market, yet most research and regulation continues to focus on a limited selection of rather well-known long-chain PFASs, particularly perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA) and their precursors. Continuing to overlook the vast majority of other PFASs is a major concern for society. ...

When subjected to reducing conditions, jarosite may undergo reductive dissolution, thereby releasing As, Sb, and Fe²⁺ coincident with a rise in pH. These conditions can also trigger the Fe²⁺-induced transformation of jarosite to more stable Fe(III) mineral ...
