In Hebrew, the Dead Sea is called Yam ha-Melah, the “sea of salt.” Now measurements show that the sea’s salt has profound effects on the chemistry of the air above its surface.
The atmosphere over the Dead Sea, researchers have found, is laden with oxidized mercury. Some of the highest levels of oxidized mercury ever observed outside the polar regions exist there. (more…)
