Urine, serum, plasma, whole blood, red blood cells, feces, hair, fingernails … the list goes on. How do you decide what biological sample(s) to use for element analysis? Can results be compared to scientific literature or do they have clinical significance? Is it possible for values to be elevated or low in one sample type and normal in another? Do test results indicate recent intake, body burden, acute toxicity, chronic toxicity, deficiency, or homeostatic regulation? These are just some of the questions facing a testing laboratory when they want to develop and validate essential and toxic element profiles that will provide clinically meaningful results.

Bioaccumulation is the concentration of toxic substances by an organism over an extended period of time. This occurs in all species, and is magnified progressively up the food chain.

Toxic elements we consume in liquids and foods, breathe in from the air, or absorb through our skin are retained in the body for different durations, depending on their chemical properties. The amount of time it takes for the body to eliminate half of a specific substance is called its half-life.

Toxic heavy metals such as cadmium, mercury, and lead can accumulate over a lifetime and have long half-lives in different organs and tissues.

Colorado Mine Spill Makes High Levels of Toxic Metals a Threat to Humans & Wildlife

Posted by Ted Zava on Monday, 17 August

This breach resulted in the release of 3 million gallons of toxic waste into Colorado’s Animas River. The waste stained the river yellow and continued to travel downstream into the San Juan River. The Animas and San Juan Rivers are a source of drinking and irrigation water, are heavily used for recreation, and are home to a wide variety of wildlife.
