Soil sampling at the Eberle site revealed a small amount of heavy metal contaminants.

Harvesting the hyacinth served not only to unclog the river, but also to remove a lot of the heavy metal contaminants.

Subsequent exposure to additional heavy metal contaminants from dentistry and other sources can additionally weaken the body's defense systems.

Both of these materials are heavy metal contaminants and may be harmful to the patient.

After they reach maturity, the plants - which now contain the heavy metal contaminants in their tissues - are removed and disposed of as hazardous waste.

Furthermore, magnetic nanoparticles offer an effective and reliable method to remove heavy metal contaminants from waste water.

The process can be reversed to collect a highly concentrated solution of metal contaminants.

High levels of metal contaminants have been measured in tissues in many areas of the globe.

Migration of metal contaminants must also be considered whenever modifying subsurface oxidation-reduction potential.

When a metal contaminant is introduced into the product an unequal disturbance is created.
