#Mercury is highly toxic, especially to babies and children, impacting the #brain and #nervoussystem. Coal plants are the dominant cause of mercury emissions in the US. Once emitted, mercury can turn into #methylmercury, polluting land, water and air and can accumulate in fish.

5/11 Expert alarm: University of Western Ontario professor Brian Branfireun warns Kinross's wastewater contains sulphate, which can worsen existing mercury contamination.
Sulphate helps bacteria convert mercury into methylmercury — an even MORE toxic form.

A conceptual diagram showing mercury cycling in an estuary with stratified water layers. River discharge delivers mercury (Hg) to the system, where it undergoes multiple transformations. Inorganic Hg (Hg²⁺) is deposited from the atmosphere and converted through redox reactions into elemental Hg⁰, which can escape to the atmosphere (evasion). Hg²⁺ also undergoes methylation into monomethylmercury (MMHg) and dimethylmercury (DMHg), with back-conversion via demethylation. MMHg and DMHg can diffuse between sediment and water, and resuspension returns buried Hg to the water column. Wind, tidal inflow, and ocean export influence water movement. The water column is divided into a mixed layer and a stratified bottom layer.
He shows that as estuaries become more stratified, they transport more riverine Hg out to the coastal ocean. But finds surprisingly that slightly stratified systems (and not highly stratified or well-mixed ones) export the most #methylmercury (MeHg), Hg's more toxic form. Figures by Cat Sephus!
🐟 Macquarie University researchers have genetically engineered #FruitFlies & #zebrafish to break down a highly toxic form of mercury & turn it into a less harmful gas.
⚠️ This could one day be a promising approach to protect from #methylmercury in food & the environment.

Scientists found a way to clean up #methylmercury, a dangerous pollutant that builds up in our #environment due to human activities. Fish & flies can be engineered to break down this form of #mercury and remove it from their bodies as a less harmful gas… (1/2) lighthouse.mq.edu.au/article/febr...

Emperor penguins lead to discovery of new detoxification pathway for mercury:
"[they] found that emperor penguins detoxify mercury with both sulfur and selenium, a new pathway for a marine predator."

1/4 #Methylmercury (MeHg) is a #PublicHealth concern, especially for developing brains. Study reports that wild-caught freshwater fish in China have lower #MeHg levels than in the US due to shorter food chains and younger fish. Understanding regional differences is key to tackling #MercuryPollution
