某些铬化合物可致肺癌早已被公认。但迄今因癌死亡率的增高主要见于生产铬盐的工人。在合成和使用铬染料、金属镀铬、金属镀铬时磨光零件的条件下仅有个别病例死于支气管癌。过去认为只有六价铬化合物才具有致癌作用,然而在动物实验中发现金属铬、烘烧铬矿石和氧化铬均有致癌作用。目前公认致癌作用不决定于铬化合物的原子价,而决定于其溶解度。溶于酸但不溶于水的铬化合物被认为是最危险的。在生产铬铁合金时工人经常受到难溶
Some chromium compounds can cause lung cancer has long been recognized. However, up to now, the increase of cancer mortality is mainly found in workers who produce chromium salts. In the synthesis and use of chrome dye, metal chrome, chrome metal chrome polished parts conditions only died of bronchial cancer. In the past, only hexavalent chromium compounds were considered carcinogenic. However, in animal experiments, it was found that metallic chromium, burnt chrome ore and chromium oxide have carcinogenic effects. It is generally accepted that carcinogenesis does not depend on the valence of the chromium compound, but rather on its solubility. Chromium compounds that are soluble in water but insoluble in water are considered the most dangerous. Workers are often poorly soluble in the production of ferrochromium
