What’s Wrong with the old adage, “The Dose Makes the Poison?”
Very good info from Living on Earth with Steve Curwood, a weekly environmental news and information program distributed by Public Radio International. :
“When toxicologists test a chemical’s safety they typically use high doses to find health problems. But that approach has missed the potential dangers of some substances that can be hazardous in tiny amounts. They’re known as endocrine disruptors because they mimic or block hormones. Some, like bisphenol A, and phthalates, are common ingredients in plastics and other consumer items.
Recently, the Government’s National Institute of Environmental Health Sciences published a paper challenging regulators to change chemical safety tests to reflect this emerging scientific understanding about low doses. Dr. J. Peterson Myers is the lead author.”
Pete Myers explains about testing, hormones, genes and more. Go to full article here.
