【Basic Knowledge of Occupational Health】Occupational Carcinogens
Thread Content
There are many carcinogens, so what are occupational carcinogens? The definition in GBZT224-2010 \"Terminology of Occupational Health\" is: a causative factor that can lead to occupational tumors. A few definitions are attached: Established human carcinogens: Substances for which there is sufficient evidence of their carcinogenicity to humans. Potential human carcinogens: Substances for which there is limited evidence of carcinogenicity in humans, but sufficient evidence in experimental animals. Suspected carcinogen: Limited evidence of carcinogenicity in humans, and insufficient evidence in experimental animals ； Or refers to substances for which there is insufficient evidence of carcinogenicity in humans, but sufficient evidence in experimental animals.
Carcinogenic factors that can cause occupational tumors
(1) Identify carcinogens. Such as coke tar, aromatic amines, asbestos, chromium, mustard gas, chloromethylethyl ether, vinyl chloride, and radioactive substances ； (2) Suspected carcinogens. Such as cadmium, copper, iron, and nitrosamines, etc ； (3) Potential carcinogens. Such as cobalt, zinc, lead, etc.
Occupation-related factors that can cause tumors are known as occupational carcinogens. Cancers caused by occupational carcinogens are known as occupational cancers. Substances that cause occupational cancer are known as occupational carcinogens. Occupational carcinogens can be divided into 3 categories: (1) Proven carcinogens, such as coke tar, aromatic amines, asbestos, chromium, mustard gas, chloromethane, vinyl chloride, and radioactive substances. (2) Suspected carcinogens, such as cadmium, copper, iron, and nitrosamines, etc., but this has not been confirmed by epidemiological studies. (3) Potential carcinogens: substances that have shown positive results in animal experiments and are carcinogenic, such as cobalt, zinc, and lead.

Carcinogenic factors that can cause occupational tumors.
The main occupational carcinogens include: (1) Confirmed carcinogens. Such as coke tar, aromatic amines, asbestos, chromium, mustard gas, chloromethylethyl ether, vinyl chloride, and radioactive substances ； (2) Suspected carcinogens. Such as cadmium, copper, iron, and nitrosamines, etc ； (3) Potential carcinogens. Such as cobalt, zinc, lead, etc.
Occupational cancer refers to cancer that occurs in people who are engaged in a particular occupation. The main occupational carcinogens are: (1) Confirmed carcinogens. Such as coke tar, aromatic amines, asbestos, chromium, mustard gas, chloromethylethyl ether, vinyl chloride, and radioactive substances ； (2) Suspected carcinogens. Such as cadmium, copper, iron, and nitrosamines, etc ； (3) Potential carcinogens. Such as cobalt, zinc, lead, etc.

Occupational carcinogens: Substances that can cause occupational tumors (referring to specific types of tumors that develop as a result of exposure to carcinogenic factors in the work environment, after an extended incubation period; for example: a) lung cancer (or pleural mesothelioma) caused by asbestos)； b) Bladder cancer caused by benzidine ； c) Leukemia caused by benzene ； d) Lung cancer caused by chloroform (or dichloromethane) ； e) Lung cancer (or skin cancer) caused by arsenic ； f) Hepatic angiosarcoma caused by vinyl chloride ； g) Lung cancer caused by coke oven emissions ； h) Lung cancer caused by hexavalent chromium compounds. ) the causative factors. Including identified human carcinogens. Possible human carcinogens and suspected carcinogens
