title: The leaching of nickel from new and used metal spectacle frames.
abstract: Fifty "used" and 373 new spectacle frames were tested for evidence of nickel release using dimethylglyoxime and ammonia. Nearly all the "used" frames (96%) tested positive. A lower proportion (24.5%) of new frames showed evidence of nickel leaching. It is suggested that this is evidence of non-conformance with the current British Standard although all our suppliers believed that their frames conformed with BS 6625 (1985).
