Heavy Metals


Heavy metals are metallic elements that have a high density compared to water. Heavy metals are naturally found in the Earth's crust. They cannot be broken down or destroyed. Small amounts of these metals enter our bodies in food and drinking water. Some heavy metals, in the right amounts, are called trace elements and are essential for all life. Cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), molybdenum (Mo), nickel, (Ni), manganese (Mn), and zinc (Zn) are essential to enzymes in the human body. However, at higher concentrations trace metals become classified as harmful heavy metals. There is a fine line between safety and toxicity. Others metals have no known benefit for health. Examples of these are lead, which is found in paint in old homes as well as drinking water; arsenic, which can be found in well water; and mercury, which can build up in fish and shellfish that we consume.

Heavy metals are especially dangerous because they can “bioaccumulate.” Metals accumulate in living things when they are taken in and stored faster than they are metabolized or excreted. This means metals continue to concentration in our organs over time. Cadmium, chromium, lead, arsenic and mercury are proven to cause organ damage and cancer.

Heavy metal contamination and public health

In the last few years, there has been an increasing public health concern about water contamination by these metals. Heavy metals can enter a water supply through industrial pollution and landfill waste, lead water pipes, lead solder, plumbing fixtures and from acidic rain breaking down soils and releasing heavy metals into streams, lakes, rivers, and groundwater. Human exposure to heavy metals has risen dramatically. Children, pregnant women and immuno-compromised individuals. Municipal water supplies and well water can be contaminated with metals and should be tested to insure the safety of you, your family and pets.


Find out by trying our Heavy-Metals Pre-Check which detects traces of more than 20 different Toxic Heavy Metals. It serves as a first alert warning if a thorough (and expensive) lab test is warranted.
