Environmental neurotoxins, such as lead, methyl mercury, polychlorinated biphenyls (PCBs), and environmental tobacco smoke (ETS), are widely disseminated in a child’s environment.
What are examples of neurotoxins?
Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol (drinking alcohol), glutamate, nitric oxide, botulinum toxin (e.g. Botox), tetanus toxin, and tetrodotoxin.
What is an example of an environmental toxin?
For some, the term “environmental toxin” evokes only man-made pollution, but naturally occurring substances can be just as harmful. Cyanobacteria (blue-green algae) are toxic to humans, as are some animal venoms, mushrooms, and molds.
What pollutants are neurotoxins?
Some of the common sources of environmental pollutants related to neurotoxic manifestations are industrial waste, pesticides, automobile exhaust, laboratory waste, and burning of terrestrial waste.
What does environmental toxins mean?
Definition of environmental toxin
: a small amount of poison found in air, water, food, etc.
What are neurotoxic effects?
Neurotoxicity is defined as any adverse effect on the structure or function of the central and peripheral nervous systems at the result of a diversity of biological, chemical, or physical agents.
What foods are neurotoxins?
Dr. Melissa Lem shows us some common foods that can harm your health, and explains why we should cut them out.

- Grilled Meat. Toxin: Free Radicals. …
- Peanut Butter. Toxin: Aflatoxin. …
- Tuna. Toxin: Mercury. …
- Butter-Flavoured Microwave Popcorn. Toxin: Diacetyl.
How can the environmental toxicants affect their health?
While the studies reviewed here focus on how developmental exposure alters vulnerability to infectious disease, early life exposure to environmental insults can lead to a number of adverse health outcomes in adulthood, such as cardiovascular disease, stoke, obesity, and cancer [10–12].
What are 5 harmful environmental toxins that stay in the ecosystem and our human system?
- Hazardous/Toxic Air Pollutants.
- Per- and Polyfluoroalkyl Substances (PFAS)
- Pesticide Chemicals. Glyphosate.
- Polychlorinated Biphenyls (PCBs)
How does lead affect the environment?
Lead can remain in the environment as dust indefinitely. The lead in fuels contribute to air pollution, especially in urban areas. Soils near highways, freeways, and smelting facilities have higher levels of lead than soils in other areas because of their exposure to lead dust, which accumulates over time.
How do environmental factors and toxins cause disease?
Examples include: Chemicals in cigarettes are known to cause lung cancer. Exposure to asbestos, an insulating material found in some older buildings, can cause tumors, lung cancer, and other diseases. Wood-burning stoves and poorly vented gas ranges can produce smoke or gases that can cause breathing problems.
How does mercury affect the environment?
Mercury is a persistent, bioaccumulative, toxic pollutant. When released into the environment, it accumulates in water laid sediments where it converts into toxic methylmercury and enters the food chain.
