The treatment of acute poisoning caused by inhalation of large amounts of cadmium oxide fumes is the same as that of general irritant gas poisoning. The key is to prevent pulmonary edema.
The scene should be evacuated as soon as possible, keep quiet, bed rest, inhalation of oxygen, keep the respiratory tract open, 10% silicone atomized inhalation can be used to eliminate the foam, the adrenocorticotropic hormone can reduce the capillary permeability, and it is appropriate to use the early quantitative. Limit fluid intake, give antibiotics to prevent secondary infection, acute ingestion of cadmium poisoning is mainly symptomatic treatment, give a large number of rehydration, injection of atropine used to stop vomiting and eliminate abdominal pain.
Chronic cadmium poisoning caused by kidney damage, dietary calcium and phosphate intake should be increased, the supply of adequate zinc and protein, metal complexing agent calcium disodium edetate (caNa2EDTA) can increase the cadmium discharge, but can aggravate the damage to the kidneys, the use of the current acute and chronic poisoning are not advocated. It has been reported that oral administration of nitrilotriacetic acid (NTA) can promote cadmium excretion (mainly through feces), thus reducing accumulation in the body without impairing renal function.
In order to prevent cadmium poisoning, melting, the use of cadmium and its compounds, should have good ventilation and airtight devices. Welding and electroplating process should have the necessary exhaust equipment, the operation should wear a personal gas mask. Should not eat and smoke in the production site. China's maximum permissible concentration of cadmium oxide in the production site is 0.1mg/m3.
Cadmium-plated ware can not store food, especially vinegar and other acidic food.
Cadmium contamination of the soil, can cause public disease pain disease. Cadmium pollution of the soil, mainly through two forms, one is the cadmium in the industrial exhaust diffuse around with the wind, through natural deposition, accumulation in the soil around the factory, the other way is the cadmium-containing industrial wastewater irrigated farmland, so that the soil is contaminated by cadmium. Therefore, in order to prevent cadmium pollution of the environment, we must do a good job of environmental protection, the strict implementation of cadmium environmental health standards.
Cadmium is not as well known as mercury and lead. Cadmium is a harmful element in the natural world, mostly in the chemical state, the content is very low, the atmosphere contains cadmium is generally no more than 0.003 μg / m 3, no more than 10 μg / liter of water, no more than 0.5 milligrams per kilogram of soil. Such low concentrations will not affect human health. Cadmium is often born with zinc, lead and other ****. Environmental experts, from the sky to the ground, cadmium is widely present in the environment. After the environment is polluted by cadmium, cadmium can be enriched in organisms, through the food chain enriched in other organisms Hugh, and then through food, water, smoking, or other ways, into the human body, when the cadmium concentration reaches a certain level, cadmium poisoning will occur. At the same time, cadmium is a kind of heavy metal beneficial to human beings, widely used in electroplating industry, chemical industry, electronics industry and nuclear industry and other fields.
