Dangers of Eating Fish from Lake Erie or Lake Ontario
Lakes Erie and Ontario are known for their beauty and recreational opportunities. However, it is important to be aware of the dangers of eating fish from these lakes due to potential contamination.
Mercury: Mercury is a heavy metal that can accumulate in fish tissue. Exposure to high levels of mercury can cause neurological problems, developmental delays in children, and other health issues.
PCBs (Polychlorinated Biphenyls): PCBs are industrial chemicals that have been banned in the United States since 1979. However, they persist in the environment and can accumulate in fish. PCBs have been linked to cancer, reproductive problems, and developmental disorders.
Dioxins: Dioxins are toxic chemicals that are produced by industrial processes. They can accumulate in fish and have been linked to cancer, reproductive problems, and immune system disorders.
Eutrophication: Eutrophication is a process that occurs when excessive nutrients enter a body of water, leading to algal blooms. These blooms can produce toxins that can contaminate fish and make them unsafe to eat.
Health Advisories: The Environmental Protection Agency (EPA) and local health departments issue health advisories for fish consumption in Lake Erie and Lake Ontario. It is important to follow these advisories to reduce the risk of exposure to contaminants.
