Mercury Levels in the Surface Ocean Have Tripled Since Industrial Revolution

Emissions from the toxic trace metal have increased considerably as a result of anthropogenic activities, like gold mining and fossil fuel combustion. In the ocean, inorganic mercury is converted into toxic methyl mercury, which can accumulate in fish… and people, ultimately. “It would seem that, if we want to regulate the mercury emissions into the environment and in the food we eat, then we should first know how much is there and how much human activity is adding every year,” says Carl Lamborg from Woods Hole Oceanographic Institution in a news release.
Current estimates of mercury present in the ocean are mostly based on computer modeling studies — and scientists remain uncertain about these values
