DID YOU KNOW?
Approximately half the mercury in the atmosphere comes from human activity, including coal combustion and industrial processes. [3] While mercury occurs naturally, its toxic effects are anything but harmless.
KNOW THE RISK
- Mercury (chemical symbol Hg) is a naturally occurring heavy metal that is liquid at room temperature and highly toxic in all forms. [1]
- It’s found in thermometers, barometers, fluorescent bulbs, batteries, and some electrical switches, especially in older equipment. [1]
- Eating fish or shellfish high in methylmercury is one of the most common ways people are exposed. Large fish like swordfish and king mackerel can accumulate high levels. [1]
- Chronic exposure affects the nervous system, kidneys, and immune system. It can impair memory, coordination, and vision — and is especially dangerous for pregnant women and young children. [1]
MITIGATE THE RISK
1. Limit Fish High in Mercury
- Choose seafood low in mercury like salmon, tilapia, shrimp, and sardines. Avoid large predatory fish, which contain higher concentrations. [2]
2. Buy Mercury-Free Products
- Choose digital thermometers, LED lights, and batteries that don’t contain mercury. Many safer alternatives are available today. [2]
3. Handle Breakages Carefully
- If a mercury-containing device breaks (like a thermometer or bulb), ventilate the area and follow EPA cleanup guidelines — never use a vacuum to clean up mercury. [2]
4. Avoid Mercury Dental Fillings
- Ask your dentist about mercury-free options such as composite or ceramic fillings, especially if you have sensitivities or multiple amalgam fillings. [2]
MERCURY SAFETY REMINDER
Mercury may seem like a relic from the past, but it still shows up in homes, workplaces, and the environment. Limit exposure through safer products, informed food choices, and proper cleanup practices. A little knowledge goes a long way toward protecting your health.
