The Effects of PCBs to the Nervous and Endocrine Systems

Polychlorinated biphenyls or PCBs have been banned in the United States since 1979. Before this ban was imposed by the Environmental Protection Agency (EPA), PCBs were widely used for a variety of industrial and commercial processes. These complex c chemical compounds proved to be particularly useful because they were nonflammable, and had the ability to withstand high temperatures and insulate electricity. As a result, its sole manufacturer in the U.S. earned huge success from the product and quickly became a leader in the chemical industry.

Unfortunately, it became clear that Monsanto had been aware of the devastating effects caused by PCBs to human health and the environment and opted to continue operations despite this knowledge. As a result, plenty of Americans continue to grapple with the risks caused by prolonged PCB exposure.

Toxic Monsanto PCBs can affect a person’s health in many different ways. The most notable health risk is the fact that PCBs are classified as a probable human carcinogen. Aside from cancer, PCBs can also affect the human body in other ways. Several scientific studies found that PCBs can some impairment in the nervous and endocrine systems.

According to a fact sheet by the EPA, PCB exposure in newborn monkeys resulted in a significant decline in cognitive development. Researchers found that monkeys exposed to PCBs can suffer deficiencies in visual recognition, short-term memory, and learning ability. Similar studies conducted in humans show a similar pattern. The EPA also points to a scientific study that showed how PCBs can cause disruption in the endocrine system of both humans and animals. In particular, PCBs have been shown to affect thyroid hormone levels.

These results show that PCB exposure can cause significant threats to an individual’s health and well-being. As such, it’s important that the public are made aware of how they can mitigate the risk of exposure to such toxic chemicals. The people most at risk to PCB exposure are workers who come into close contact with older models and materials that have PCBs. Workplaces should have proper regulations in place to ensure that employees are protected from prolonged chemical exposure.
