Our very scientific (in the best sense) neighbor recently cautioned me about
a bag of old abrasive I was planning to spread among some ornamentals for the
interesting sparkle effect...he said abrasives typically contain substantial
amounts of heavy metals including arsenic and cadmium.

But per Alex McGregor's post those would be tied up in the composite and
therefor not a threat.
