Factors affecting occupational health

Environmental hazards such as light pollution and medical disinfection of artificial ultraviolet light sources such as welders can lead to electro-optic dermatitis or electro-optic ophthalmia. Industrial wastes, discarded cables, wires and electrical equipment contain heavy metals, which pollute the soil environment. Chlorofluorocarbons as refrigerants in air conditioners and hydrochlorofluorocarbons as foaming agents in insulation layers have destroyed the atmospheric ozone layer. The waste printer and copier toner cartridges contain a variety of heavy metals and organic pollutants, which are difficult to degrade and threaten the ecological environment. Mercury in waste batteries overflows into soil or water, enters human body through crops, and damages human kidneys. Insulating oil and waste engine oil in vehicles are hazardous wastes, which are difficult to decompose naturally and cannot be repaired in a short time after infiltrating into soil, and pollute drinking water sources after infiltrating into groundwater. Lubricating oil: Acute inhalation may cause dizziness, nausea, oily pneumonia or contact dermatitis. Computers, cameras, video cameras and liquid crystal displays contain compounds of mercury, lead, cadmium and chromium. Mercury mainly damages kidneys and brain; Hexavalent chromium can be absorbed by cell membrane to produce toxicity, cause bronchial asthma and damage DNA. A large number of germs derived from domestic garbage, if not handled properly, can easily cause the spread and spread of various diseases. Natural resource consumption The establishment and operation of power system should avoid consuming too much natural resources, such as land resources and water resources. Domestic wastewater, automobile exhaust, kitchen fume, human body emissions and equipment heat and other emissions produce harmful factors, pollute the environment and threaten human health.
