Sixty-two pairs of jeans were collected and tested. Fourteen pairs of jeans (23%) were new, and 48 pairs (77%) were preworn. Ten pairs (16%) tested positive for nickel: 6 pairs (43%) of new jeans and 4 pairs (8%) of preworn jeans. There were two preworn pairs of jeans representing one brand of jeans in which one pair tested positive for nickel and the other tested negative. Two brands represented in the study included both one preworn pair and one new pair. In one brand, only the preworn jeans tested positive for nickel; in the other brand, only the new pair tested positive for nickel. After one coat of clear nail polish was applied to the nickel-positive blue-jean metal buttons, all ten pairs tested negative with DMG. Only seven pairs of these blue jeans underwent two wash/dry cycles, owing to logistical constraints. All seven pairs tested negative after each two wash/dry cycles (Fig 1).
