Avoid skin-lightening products with mercury
Mercury is a harmful metal that can damage the skin, nervous system, and kidneys. People who have been exposed to mercury may not look or feel sick, but repeated exposure can result in skin rash, tingling or numbness, tremors, irritability, memory loss, and depression. Mercury poisoning can be especially harmful to children and can increase the risk of miscarriage during pregnancy.
Skin-lightening products containing mercury are banned in the United States. These products are often marketed as beauty creams, pearl creams, skin bleaching, fading, evening, brightening, or whitening products. They are usually marketed as treatments for uneven skin tone, acne, age spots, freckles, and wrinkles. Adolescents may use these products as acne treatments.
- Check the label: If the words "mercurous chloride," "calomel," "mercuric," "mercurio," or "mercury" are listed on the label, the product contains mercury and should be avoided.
- Be cautious of unlisted ingredients: Mercury may not always be listed as an ingredient on the label. Be wary of products that do not list any active ingredients or have missing or incomplete ingredient lists.
- Avoid products marketed towards certain communities: These products are often sold in shops catering to Latino, Asian, African, or Middle Eastern communities.
- Report prohibited products: If you come across skin-lightening products that contain mercury, report them to the appropriate authorities. In New York City, you can call 311 to report sales of prohibited products.
- Dispose of mercury-containing products properly: Do not throw these products in the trash. Place unused products in a sealed plastic bag until they can be disposed of properly at a hazardous waste disposal event or collection program.
- Consult a doctor: If you have used skin-lightening products and are experiencing symptoms of mercury exposure, talk to your doctor and ask for a blood and urine mercury test.

Don't eat fish with high mercury levels
Mercury is a naturally occurring element found in the air, water, and food. Most people are exposed to mercury through their diet, and fish is a common source of mercury exposure. Fish absorb mercury from the water they live in, and this mercury is in the form of methylmercury, which is highly toxic.
Predatory fish that are higher up in the food chain tend to contain more mercury, as they eat smaller fish that already contain mercury. Examples of predatory fish with high mercury levels include shark, blackfish (bowfin), catfish, jack fish (chain pickerel), warmouth, and yellow perch. In addition, black crappie caught south and east of Interstate 95 has been found to have high mercury levels.
Consuming high levels of mercury can be harmful, especially to developing fetuses and young children. Mercury can affect the nervous system and brain development, causing delays in reaching developmental milestones. Unborn babies are at the greatest risk, and exposure to methylmercury in the womb can impact their nervous systems. Research has shown that women who consumed significant amounts of fish with high mercury levels during pregnancy had children with delayed brain development.
Therefore, it is essential to limit the consumption of fish with high mercury levels. Pregnant women, women planning a pregnancy, and young children should avoid eating fish with high mercury levels altogether. For healthy adults and older children, such fish should not be eaten more than once a week. Eating a variety of fish and being mindful of portion sizes can help reduce mercury intake.
To make informed choices, individuals can refer to guidelines and advisories provided by organizations such as the U.S. Environmental Protection Agency, Food and Drug Administration, and local health departments. These sources offer information on fish species with high mercury levels and provide recommendations for safer alternatives. Additionally, individuals can support initiatives that aim to reduce mercury pollution, such as environmental quality standards and restrictions on mercury use in products. By being mindful of both personal dietary choices and broader environmental efforts, we can collectively work towards minimizing the presence and impact of mercury pollution.

Reduce coal-burning for energy
Mercury is a dangerous neurotoxin that can cause neurological and developmental damage in humans and animals. It is found in many types of rock, including coal, and is released into the environment as air pollution when coal is burned in power plants.
To reduce coal-burning for energy and, in turn, lower mercury pollution, it is important to first understand where your energy comes from. Contact your utility or electricity provider to find out. If your energy comes from coal-burning power plants, you can check if your provider offers alternative energy sources, such as natural gas, nuclear power, wind, or solar. Switching to a different energy source may result in changes to your electricity bill, so it is important to understand the potential costs.
Another way to reduce coal-burning for energy is to advocate for and support the development and implementation of cleaner technologies. This includes technologies aimed specifically at controlling mercury emissions, such as activated carbon injection, which can lower mercury emissions from lignite coal. Additionally, technologies that remove impurities from coal or make coal more energy-efficient can reduce the amount of coal burned and, consequently, the amount of mercury released into the environment.
On a larger scale, governments and regulatory bodies play a crucial role in reducing coal-burning for energy. The United States Environmental Protection Agency (EPA), for example, has implemented regulations such as the Mercury and Air Toxics Standards (MATS) to reduce toxic air pollutants, including mercury, from coal- and oil-fired power plants. Compliance with MATS involves power plants installing controls or updating operations to meet the standards, which offer significant health benefits. Similarly, national initiatives, such as setting environmental quality standards and restricting mercury use in specific products, contribute to reducing coal-burning and mercury pollution.
In summary, reducing coal-burning for energy requires a combination of individual actions, technological advancements, and regulatory measures. By understanding our energy sources, switching to alternative energy when possible, supporting clean technologies, and advocating for regulatory standards, we can collectively work towards reducing coal-burning and mitigating mercury pollution.
