Bromine in the Dead Sea Makes Mercury Above it More Lethal

Researchers thought it only happened at the poles; new research between Israel and the US shows that bromine above the sea can make mercury way more toxic in fish.Photo retrieved from:

“The research, led by scientist Daniel Obrist and colleagues at Nevada’s Desert Research Institute with a group of Israeli researchers at Hebrew University, found that mercury was concentrated into the most toxic form in the air above the Dead Sea.

The atmosphere over the Dead Sea, researchers found, is laden with oxidized mercury, a much more toxic form of Mercury than the elemental form. The finding was surprising, as such high levels of oxidized mercury have only been found at the polar regions.

“We’ve found near-complete depletion of elemental mercury – and formation of some of the highest oxidized mercury levels ever seen – above the Dead Sea, a place where temperatures reach 45 degrees Celsius,” Obrist noted.

The findings are a concern because oxidized mercury threatens the food supply more readily than the elemental form. That is because, once oxidized in what scientists call elemental mercury depletion events – it is then readily deposited on a surface such as the ocean, and can then find its way into the food chain.”

  • Why has no body commented on this article? it is a very serious matter that we should all be aware of, and i hope more people become less ignorant and stop ignoring the situation we have here.

  • Dear Maria,
    It is a very serious issue indeed. Thank you for your words.
