Mercury has the potential to harm the neurological system, brain, kidneys, and growing fetuses. Mercury may seep out of historic things over time when seals deteriorate or when the goods are broken, dropped, or relocated incorrectly. Buy no antiques containing mercury. If you have a choice, buy items with original packaging from reputable dealers. Here are some tips for avoiding exposure to mercury: Don't handle old coins or buttons that are in poor condition. These items may contain more mercury than others. Don't eat old clocks or other electrical equipment. Stay away from third-hand smoke and avoid smoking candles or lamps. Check with your local government agency about disposing of items that contain mercury. They can tell you where there are disposal sites in your area.
