Heavy Metals, Health, Nutrition, and Architecture


Test playground and garden soil for Heavy Metals. 


Read this interview from 1998 with Paula Hewitt, Selim Iltus, and other proponents of testing playgrounds and gardens for Heavy Metals. Oddly, the article misreads the "heavy metals" as being the metal of play equipment instead of metals in the soil. Toxicity is mentioned instead as being found in sandboxes. Hmm.  Please. Test your soil. 

At Playgrounds, Heavy Metal Is Out, Gardening Is In
