In case you missed it, as I did for several months, Scientific American magazine published an article titled, "Mixing It Up: Harmless Levels Of Chemicals Prove Toxic Together," that supports key points made in The Hundred Year Lie.

Citing several new science studies, the article describes "a growing body of work showing that chemicals in combination can produce a wide range of effects even at low concentrations."

Pesticides and phthalates --chemical softners used to make plastics flexible-- were two compounds noted as having some of the more powerful observed effects when mixed.

"These findings on mixtures pose an incredible challenge for regulators," continued the article. "With tens of thousands of chemicals in regular use worldwide, assessing which combination might prove harmful is a gargantuan task." Given today's limited budgetary resources and technology, the article might have added that the task is impossible and the potential threats to human health are beyond measure.
