Heavy metals are one type of toxins that contaminate water, food and air via industry, pollution, pesticides, emissions and exhaust. They can interfere with various processes in the body, so you must detoxify and clear heavy metals from your system to avoid damage.
These pollutants can increase your risk of developing several health conditions. Elevated levels of heavy metals in the body can damage the liver, cardiovascular system, kidneys and brain. Infertility, diabetes, dementia, metabolic issues like thyroid disorders and some types of cancers have been associated with heavy metal exposure.
Some people are at an elevated risk of heavy metal toxicity:
- those who smoke
- those with jobs or hobbies which expose them to metals
- those living in older homes
- those living in areas with contaminated drinking water
Common Heavy Metals That Can Impact Health
Toxic metals like arsenic, mercury, cadmium, aluminum and lead are common environmental contaminants that can impact our health in many ways.
Acute toxicity may present with more obvious, severe symptoms like vomiting, difficulty breathing and impaired cognition, while long-term chronic build-up of these metals can cause more subtle symptoms like fatigue, digestive issues, depression and impaired metabolism.
Arsenic
Sources of Arsenic Exposure
We are exposed to arsenic through:
- consumption of conventionally raised poultry (via their feed)
- wood preservatives on treated wood
- coal combustion
- drinking water in some areas
- pesticides, insecticides & fungicides
- paints & pigments
- tobacco smoke
- some rice products
- some cosmetics
- seafood from contaminated waters
Health Impacts of Arsenic
Arsenic occurs in an inorganic and organic form, with inorganic arsenic compounds such as those found in water being highly toxic.
Initial signs of arsenic exposure often show up in the skin, with pigmentation changes, skin rashes and pre-cancerous lesions. With long-term exposure to arsenic, further adverse effects may develop.
Arsenic is a known carcinogen associated with liver, lung, skin, bladder and kidney cancer. It also has developmental and neurological impacts, contributing to headaches, mood changes, vertigo and weakness. Arsenic has also been associated with metabolic issues and may contribute to diabetes.
Lead
Sources of Lead Exposure
We are exposed to lead through:
- drinking water
- auto exhaust
- batteries
- cigarette smoke
- coal combustion & pollution
- hair dyes
- lead pipes
- cosmetics
- newsprint
- paints
- pesticides
Health Impacts of Lead
Lead toxicity is one of the more common forms of heavy metal toxicity, especially in children. Ingestion and inhalation of lead paint dust are common routes of exposure, as well as food stored in lead cans and contaminated water.
When the body is deficient in adequate nutrition, it may use toxic metals as stand-ins for essential nutrients. For example, calcium can be replaced by lead, which deposits in bone and can contribute to poor bone health and osteoporosis. Lead accumulation in the blood is associated with increases in hypertension and cognitive and developmental issues in children.
Mercury
Sources of Mercury Exposure
We are exposed to mercury through:
- dental amalgams
- coal combustion & pollution
- fish & seafood from polluted waters especially sharks, swordfish, king mackerel, tile fish, bass, walleye & pickerel
Health Impacts of Mercury
Mercury toxicity can arise through ingestion of mercury or mercury salts or by inhalation of mercury vapor. It often concentrates in the brain and kidneys and can also cross the placenta.
Mercury competes with and displaces iron and copper from the active site of enzymes involved in energy production, which can have metabolic, neurologic, gastrointestinal and cardiovascular impacts.
Cadmium
Sources of Cadmium Exposure
We are exposed to cadmium through:
- cigarettes and tobacco smoke
- industrial pollution
- auto exhaust
- batteries
- motor oil
- coffee & instant coffee
- pesticides, insecticides & fungicides
- paints & pigments
- metal coatings & solders (including canned food)
- contaminated tap water
- large ocean fish (tuna, cod, haddock, etc.) from contaminated waters
Health Impacts of Cadmium
As with lead, cadmium can also mimic the function of essential nutrients in the body when out of balance. Zinc can be replaced by cadmium, which often accumulates in the kidneys. Cadmium can also impact the nervous system, contributing to peripheral neuropathy.
In the body, cadmium can bind to red blood cells and become transported to the kidneys and liver. As it accumulates in the body, chronic cadmium exposure can result in decreased bone mineralization, decreased lung function and an increased risk of cancer.
Aluminum
We are exposed to aluminum through:
- aluminum foil
- teas
- auto exhaust
- cigarette smoke
- cookware
- cosmetics
- deodorants
- tap water
- pesticides, insecticides & fungicides
- pollution
Health Impacts of Aluminum
Aluminum seems to particularly harm the lungs and nervous system. Workers may develop lung issues from inhalation of aluminum dust.
The nervous system also appears to be a sensitive target for aluminum. When aluminum accumulates, it may replace magnesium which induces neurochemical changes and may contribute to dementia.

I have a chemical background so I totally appreciate this post. We have so many chemicals that we are constantly surrounded by…it’s important to limit our risks.
Dr. Jennifer L. Weinberg, MD, MPH, MBE
Thank you Janelle! I agree it is so important to take steps to protect our health through better environmental choices.
Madhuri
Interesting!! We never realize how much toxins we absorb unknowingly into our systems. I guess, we can only control the ones we know of. Can’t wait to read part two of it.
Dr. Jennifer L. Weinberg, MD, MPH, MBE
Thank you Madhuri! It can be overwhelming but also empowering to be able to take action to protect our health. I hope you find the strategies in part II helpful!
Lauren

Aluminum in deodorant, I never would have guessed that!
We have a lot of lakes around here that the fish have mercury in them so you can’t eat them if you catch them. On the plus side I hate fish so its a win win, because I am catch and release type of girl anyway. But for those who enjoy fresh trout they have to watch it.
Dr. Jennifer L. Weinberg, MD, MPH, MBE
It is unfortunate that so many waterways and therefore fish are contaminated, but I guess it works out for you that you are avoiding them anyway! Thanks for stopping by 🙂
Tricia
Reading all this really makes you wish you lived in a bubble. I can hardly imagine what all we are doing to our bodies and how much work it takes to rid ourself. I was on the isogenix program briefly and they really pushed their cleanse for help with all the toxicity of everything. I believed it helped but in the end, it was not something I could sustain and like any diet or lifestyle change or even fad, it must be sustainable to continue it.
This is a great article with a lot of great info! Thanks for sharing.
Dr. Jennifer L. Weinberg, MD, MPH, MBE
Yes, it can become overwhelming but also empowering to be informed and be able to take steps to make healthier decisions (I hope!). Thank you Tricia!
Elysha
I was just talking about this with a friend yesterday! She’s been tested for the metals in her body, and she told me that another way we absorb them is from sleeping in jewelry.
Thanks for the informative post!

Dr. Jennifer L. Weinberg, MD, MPH, MBE
Thank you for sharing Elysha! It is especially an issue to absorb toxic metals with less expensive or costume jewelry.
