📖 About Mercury
The only metal that is liquid at room temperature. Mercury is highly toxic, damaging the nervous system, kidneys, and brain. Methylmercury (organic mercury) bioaccumulates up the food chain, making large predatory fish like tuna a health concern. Despite its toxicity, mercury has a long history in medicine, mining (gold amalgam), and industry.
