Abstract
Crushed serpentine rock, quarried at Rockville, Maryland [USA], was used in large quantities for road and playground surfacing. The rock essentially consists of the fibrous serpentine mineral chrysotile (asbestos) and platy serpentines. In vitro bioassays in P338D1, a malignant mouse macrophage-like cell line, show that chrysotile is cytotoxic while the platy serpentines are not.
