Understanding Mercury Poisoning: A Threat to Human Health

Mercury is an element known for its unique properties, but it also poses significant threats to human health when exposure levels exceed safe limits. As the only heavy metal that occurs naturally in a liquid state, mercury has been used in various industries and consumer products due to its ability to dissolve other metals and imbue them with certain properties.

However, mercury poisoning can have disastrous repercussions for humans, animals, and the environment. Exposure to high levels of mercury over a short period or prolonged exposure to low levels can lead to serious health problems. Babies are particularly vulnerable to mercury poisoning, as it can impact their nervous system and brain development, impede growth, and impair learning after birth.

Mercury is also an environmental justice concern, with historically marginalized communities of color bearing the heaviest burden of air pollution. Pregnant people and developing babies face unique concerns due to mercury's ability to cross the placenta, accumulate in organs with high fat content like the brain, and impact nervous system development.

The good news is that monitoring mechanisms are now required for companies and individuals handling mercury to ensure safe levels. The Mercury and Air Toxics Standards (MATS), implemented by the EPA in 2012 and updated in 2024, have been successful in reducing emissions from coal plants and preventing mercury poisoning.

As a community of over one million parents united against air and climate pollution, we urge the EPA to consistently update MATS with the strongest new standards possible. By working together, we can reduce mercury exposure and ensure a healthier environment for future generations.
