铜尘的致突变性致癌性研究不多,大鼠试验未肯定铜的原发致癌作用。为观察铜尘致突变性,用一组六种试验,对铜和氧化铜尘的致突变性进行了测试。 材料和方法 一、化合物 金属铜粉为苏州金粉厂出品,含铜量99.9％,颗粒直径<5μ。氧化铜粉为湖南省劳动卫生研究所提供。铜和氧化铜尘混悬于1％吐温或培养基中,配制成研究所需要的各种浓度。 Mutagenicity of copper dust on carcinogenicity of small, rat experiments are not sure the primary carcinogenic effect of copper. In order to observe the mutagenicity of copper dusts, a series of six tests were conducted to test the mutagenicity of copper and copper oxide dusts. Materials and methods First, the compound metal copper powder produced for the Suzhou powder factory, containing 99.9% of copper, particle diameter <5μ. Copper oxide powder for the Hunan Institute of Labor and Health to provide. Copper and copper oxide dusts were suspended in 1% Tween or medium to prepare various concentrations required for the study.
