Endocrine-Disrupting Chemicals: What They Are & How To Avoid Them

Posted by Margaret Groves on Friday, 17 February

As a hormone testing lab, ZRT understands the importance of a well-balanced endocrine system in maintaining overall health. Hormone balance is achieved through multiple feedback mechanisms, and when any part of the system is thrown out of whack by forces beyond its control, there is a knock-on effect on the rest of the body systems that are under endocrine control. Such forces can include extreme or chronic stress, or exposure to environmental toxins that enter the body through the air we breathe or in our diets. Substances in the environment that upset the endocrine system are known as endocrine-disrupting chemicals, or EDCs.

High Air Levels of Arsenic & Cadmium May Be Linked to a Cancer Cluster in Portland, Oregon

Many residents were surprised to learn today that high levels of arsenic and cadmium are being detected at an air monitoring station in Southeast Portland, Oregon according to the state Department of Environmental Quality (DEQ)

Watch the News: Dr. Zava comments on toxin exposure in SE Portland

The state began monitoring air quality after moss samples taken from the area last October were found to be high in arsenic and cadmium. The results, which were only made public in the past few days, show cadmium at 49 times the acceptable level and arsenic at 159 times the acceptable level for air.

Of key concern is that the testing location is in an area populated with businesses, schools, and parks. It is not clear yet how long exposure has occurred or whether it is caused by a nearby glass blowing facility. As of this week, the glass blowing facility decided to cease use of arsenic and cadmium.

Could Zombies Survive on Today's Brain?

Posted by Dr. Allison Smith on Friday, 30 October

Everyone knows zombies are hungry. 

Naturally, brains are on the menu, and occasionally my six-year-old daughter expresses her concern that a zombie might eat her brain as she sleeps (thanks, ParaNorman). 

But the nerd in me can’t help but wonder why a zombie would want to eat today’s brain.

Today’s brain is full of aspartame, SSRI’s, cadmium, arsenic and mercury, phthalates, benzene metabolites, DDE and BPA. Scientific American even tells us we have fewer memories stored in our brains now that we can rely on “the cloud.” 

Eeeeww. We’ve literally turned into the human equivalent of potato chips.

Bioaccumulation of Toxic Elements - Can Persistent Low Exposure Lead to Large Problems?

Posted by Ted Zava on Friday, 02 October

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.
