Legal objectivity:

China's Ministry of Health first announced 14 kinds of occupational diseases from 1972, and revised them into 99 kinds of 9 categories in 1987. At present, there are 10 categories 1 15 statutory occupational diseases in China: pneumoconiosis 13, radiation disease1/0/,56 occupational poisoning, 5 occupational diseases caused by physical factors, 3 occupational diseases caused by biological factors and occupational dermatoses. Occupational disease diagnosis is generally carried out by units with certain special conditions authorized by the health administrative department. The most common occupational diseases are pneumoconiosis, occupational poisoning and occupational dermatosis. 1. Pneumoconiosis Pneumoconiosis is a systemic disease that mainly causes diffuse fibrosis (scar) of lung tissue by inhaling productive dust for a long time in occupational activities and staying in the lung. Pneumoconiosis can be divided into inorganic pneumoconiosis and organic pneumoconiosis according to the types of inhaled dust. Pneumoconiosis caused by inhaling inorganic dust in production labor is called inorganic pneumoconiosis. Most pneumoconiosis is inorganic pneumoconiosis. Pneumoconiosis caused by inhaling organic dust is called organic pneumoconiosis, such as cotton pneumoconiosis and farmer's lung. There are thirteen kinds of laws in China, namely: 1, silicosis 2, coal worker's pneumoconiosis 3, graphite pneumoconiosis 4, carbon black pneumoconiosis 5, asbestos pneumoconiosis 6, talc pneumoconiosis 7, cement pneumoconiosis 8, mica pneumoconiosis 9, Potter's pneumoconiosis 10, aluminum pneumoconiosis 16 and welder's pneumoconiosis. Radiation sickness 1, external radiation acute radiation sickness 2, external radiation subacute radiation sickness 3, external radiation chronic radiation sickness 4, internal radiation radiation sickness 5, radiation dermatosis 6, radiation tumor 7, radiation bone injury 8, radiation thyroid disease 9, radiation gonadism 10, radiation combined injury 1 1 according to radiation sickness. Other diagnosable radiation injuries. Occupational poisoning 1, lead and its compounds poisoning (excluding tetraethyl lead) 2, mercury and its compounds poisoning 3, manganese and its compounds poisoning 4, cadmium and its compounds poisoning 5, beryllium disease 6, thallium and its compounds poisoning 7, barium and its compounds poisoning 8, vanadium and its compounds poisoning 9, phosphorus and its compounds poisoning 10, arsenic and its compounds poisoning 65438. Uranium poisoning 12, hydrogen arsenide poisoning 13, chlorine poisoning 14, sulfur dioxide poisoning 15, phosgene poisoning 16, ammonia poisoning 17, unsymmetrical dimethylhydrazine poisoning/kloc-0. Zinc phosphide, aluminum phosphide poisoning 23, industrial fluorosis 24, cyanide and nitrile compound poisoning 25, tetraethyl lead poisoning 26, organotin poisoning 27, nickel carbonyl poisoning 28, benzene poisoning 29, toluene poisoning 30, xylene poisoning 3 1, n-hexane poisoning 32, gasoline poisoning 33, monomethylamine poisoning 34, organic fluoropolymer monomer and its pyrolysis products poisoning 35, II. Vinyl chloride 38, trichloroethylene 39, chloroprene 40, chloroprene 4 1, phenylamino and nitro compounds (excluding trinitrotoluene) 42, trinitrotoluene 43, methanol 44, phenol 45, pentachlorophenol (sodium) 46, formaldehyde 47, dimethyl sulfate 48, acrylamide 49 and dimethyl. Organophosphorus pesticide poisoning 5 1, carbamate pesticide poisoning 52, chlordimeform poisoning 53, methyl bromide poisoning 54, pyrethroid pesticide poisoning 55, occupational toxic liver disease which can be diagnosed according to the diagnostic criteria of occupational toxic liver disease 56, other occupational acute poisoning which can be diagnosed according to the diagnostic criteria of occupational acute chemical poisoning 4. Occupational disease caused by physical factors 1, heatstroke (caused by long-term work in a high temperature environment above 39℃) 2. Decompression disease (nitrogen release from blood due to deep-water diving) 3. Altitude sickness 4. Airsick. Vibration disease of arm. Occupational diseases caused by biological factors 1, anthrax 2. Forest encephalitis III. Brucellosis 6. Occupational dermatosis 1. Contact dermatitis II. Photosensitive chemical skin burn 8 7. Other occupational skin diseases that can be diagnosed according to the Diagnostic Criteria for Occupational Skin Diseases (General). Occupational eye disease 1, chemical eye burn 2. Electro-optic ophthalmia III. Occupational cataract (including radiation cataract and trinitrotoluene cataract) 8. Occupational otorhinolaryngology oral diseases 1, noise deafness 2, chrome nose disease 3, tooth erosion 9. Lung cancer caused by occupational asbestos, mesothelioma 2, bladder cancer 3 caused by benzidine, leukemia 4 caused by benzene, lung cancer 5 caused by chloromethyl ether, lung cancer 6 caused by arsenic, hepatic angiosarcoma 7 caused by vinyl chloride, lung cancer of coke oven workers 8, lung cancer of chromate manufacturers 10, other occupational diseases 1, metal smoke fever 2, occupational asthma 3, occupational allergic alveolitis 4, cotton dust. Contact with toxic chemicals, dust aerosol, abnormal meteorological conditions, high and low pressure, noise, vibration, microwave, X-ray, γ-ray, bacteria contact with dust and mold; Long-term forced posture operation and continuous oppression of local tissues and organs can cause occupational diseases, which are generally called generalized occupational diseases. Such as cervical spondylosis, scapulohumeral periarthritis, hemorrhoids and other chronic diseases caused by long-term desk work of modern white-collar workers. Some of these occupational diseases are harmful and the diagnostic criteria are clear, which are approved and published by the relevant government departments according to the national conditions, and are called narrow occupational diseases or statutory (prescribed) occupational diseases.
