铬是地壳表面最为丰富的元素之一,在自然界以二价、三价和六价化合物存在。铬化合物的工业用途甚广,可能接触铬及其化合物的行业有冶金、电镀、皮革、水泥及油漆和颜料工业等。在生产环境中,对人产生危害的主要铬化物多经呼吸道和皮肤进入机体。铬化物对人体的主要损害为慢性支气管损害、皮炎、皮肤和鼻中隔溃疡和肺癌等。随着铬作业环境
Chromium is one of the most abundant elements on the surface of the earth and is found in nature as divalent, trivalent, and hexavalent compounds. Chromium compounds are used in a wide range of industrial applications. Metals, electroplating, leather, cement, paints and pigments industries may be involved in industries that may come into contact with chromium and its compounds. In the production environment, the main chrome harmful to humans mostly enters the body through the respiratory tract and skin. Chromium on the human body’s main damage for chronic bronchial damage, dermatitis, skin and nasal septal ulcers and lung cancer. With chromium working environment
