According to a recent post at Green Daily, many sandboxes are filled with quarried quartz rocks and contains silica, all of which can give off dangerous dust. The State of California even requires a label on any sand that contains crystalline silica because it can cause lung problems.
There are sources for safe sand, however, like the cleverly titled Safe Sand Company. Their feldspathic sand is safety approved by ASTM (USA), Corporate and Consumer Affairs Canada and EN-71 (Europe), and is supposed to be great for building sandcastles.
