Heavy Metal Exposure

Research indicates that people are exposed to heavy metals in the course of everyday life, and the amount of heavy metals in each person affects their health. If the human body has too much of the wrong metals it will cause health problems. However, too little of other metals will also cause health problems. In fact, trace amounts of heavy metals like iron, chromium, and nickel are actually necessary for the human body to function optimally . For example, the absence of iron is associated with anemia and the absence of chromium is correlated with diabetes. While certain metals are required for radiant health, studies show that excessive quantities of specific heavy metals such as mercury, arsenic, lead, and molybdenum can be toxic and detrimental to well-being. Ensuring adequate levels of the needed trace metals while minimizing exposure to the harmful heavy metals is necessary to support good health.

Heavy metal exposure has increased over time due to changes in the industrial and agriculture industries. These changes include the cultivation of new plant species that influence the natural plant and animal ecosystem, and the use of hazardous substances that affect the agroecosystems. Common hazardous substances include heavy metals, pesticides and synthetic organic substances, and radionuclides . These examples are just a few delivery paths of metal exposures. Take a look at the list below to see even more ways of that humans can be exposed to heavy metals.

  • Industrial processes (waste products)
  • Urban settlements (sewerage water and roads )
  • Anti-corrosive paint
  • Secondary exposures (packaging, storage, cutlery, pots, and addivities)

Awareness of the dangers posed by the harmful heavy metals and of the necessity for the essential trace metals is important as you journey on your path to optimal health. Heavy metals imbalances can negatively impact general health outcomes, so it is important to minimize exposure and optimize detoxification pathways. We encourage our readers to continue their education about the influence of heavy metals on health.
