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

Posted by Ted Zava on Monday, 17 August

colorado.mine.spill.blog_1On August 5, 2015 the Environmental Protection Agency (EPA) accidentally breached a tunnel holding liquid waste as part of the cleanup of the Gold King Mine in Colorado.

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.

Understanding Selenium Supplementation

Selenium - Element Table

A balance of nutrients is required by our bodies to maintain good health, and selenium (Se) is an important one that often gets overlooked.

This essential element is a required component of the selenoproteins, which include those that are needed to convert thyroid hormone from the inactive to the active form, and several important anti-oxidants.

While optimal selenium levels are imperative for proper thyroid function, abnormally high selenium intake can be toxiccausing gastrointestinal disturbances, changes in nails and hair, weakness, convulsions and decreased cognitive function. So it’s important to understand the ways in which we take in selenium, both in the diet and as supplements.

Arsenic Exposure from Rice and Rice-Based Breakfast Cereals

Arsenic exposure from rice cereal

Did you know that the amount of arsenic in your public water supply is strictly regulated by the FDA, and must test below 10 ppb* total arsenic? Ironically, the food we eat has no such regulations on arsenic content, and some staple foods such as rice may contain high levels of arsenic.

Arsenic is a natural element found in soil and water at different concentrations throughout the world. There are two types of arsenic, inorganic and organic, the former being much more toxic and associated with generation of free radicals that damage tissues and potentially lead to diseases of aging and cancer. Typically, chronic long term arsenic exposure comes from private or unregulated wells, but recently rice grown in soil and irrigation water containing high levels of arsenic has been identified as a major source of arsenic exposure.

bromine_essential_element_6.6.14.jpgAccording to researchers at Vanderbilt University, bromine should be recognized as the 28th essential element for all species, from fruit flies to humans. Study results were published June 5, 2014 in Cell, and demonstrate that without bromine, collagen type IV molecules will not bond together properly to form the structural proteins of connective tissues, leading to disrupted tissue development. 1
