Fertilizer is widely used in agricultural production in China. In recent years, due to poor storage and storage of some farmers, cases of acute chemical poisoning have occurred from time to time and are on the rise, seriously endangering the physical and mental health of patients. When storing and using chemical fertilizers, farmers’ friends can effectively avoid the harm of chemical fertilizers to the human body if they follow the following methods.
Chemical fertilizer damage and symptoms of poisoning
At present, the fertilizers used in rural China mainly include nitrogen fertilizers (such as ammonium bicarbonate, ammonium chloride, urea, etc.), phosphate fertilizers (such as superphosphate and calcium phosphate), and potassium fertilizers. Among the above three types of chemical fertilizers, except that potassium fertilizer has no obvious harm to the human body, nitrogen and phosphorus fertilizers have greater toxic effects on the human body. Nitrogen fertilizer has different stimulating effects on human skin and mucous membranes. For example, lime nitrogen and ammonia can strongly stimulate respiratory mucosa and can cause acute poisoning. Ammonium bicarbonate, the largest amount of nitrogen fertilizer used, is a highly volatile fertilizer that produces a colorless, foul-smelling irritant gas even in sub-zero temperatures. This gas not only has a strong stimulatory effect on human eyes and upper respiratory tract mucosa, but also binds with the moisture of the human mucous membranes to form weakly alkaline ammonium hydroxide, denature human body proteins, saponify fat, destroy cell membrane structure, and easily cause human respiratory tract Mucositis and even burns. Its clinical manifestations are rhinitis, bronchitis and bronchitis, and there are throat-like burning pains, hoarseness, cough, sputum, chest tightness and many other conditions. Phosphate fertilizer in the transport, packaging and dust formation in the field, it is easy to stimulate the skin, eye conjunctiva and respiratory mucosa and cause inflammation, some people can also cause skin allergies or contact with certain chemical fertilizers or systemic discomfort. Therefore, when farmers use and keep chemical fertilizers, they must take effective protective measures to prevent occupational poisoning.
How to avoid fertilizer hazards
Preventing gas damage The highly volatile fertilizers such as ammonium bicarbonate should be stored in a cool and ventilated place. They should not be stored indoors. To prevent the harm and influence of harmful gases on the human body, sealed storage methods can be used: A layer of agricultural film is laid on the floor where the fertilizer is stored. After chemical fertilizers are piled on the agricultural film, the stacked chemical fertilizers are collectively covered with agricultural film, and the joints between the covered agricultural film and the ground are pressed with wet sand. After fertilisers are taken from a sealed chemical fertilizer heap, the rest should be re-enclosed as described above. This can not only effectively prevent the harmful effects of chemical fertilizers on the human body, but also reduce the loss of chemical fertilizers.
Prevention of corrosion hazards When transporting, dispensing, keeping and using chemical fertilizers, personal protection should be strengthened. Long-sleeved clothing, long-sleeved pants, masks, and protective glasses should be worn as far as possible. After the work is completed, the hands must be washed, washed, and cleaned immediately to avoid Fertilizer residue stimulates the skin. In the use of various fertilizers, we must use tools to operate, such as shovels, spoons, scoops, etc., should not direct fertilization when used to prevent corrosion of fertilizers affect human health.
Preventing Poisoning by Poisoning In recent years, examples of human and livestock eating chemical fertilizer poisoning have occurred in rural areas. In order to prevent accidental food poisoning, chemical fertilizers should not be stored together with food, vegetables, fruits, and other food products during storage. In particular, the appearance of some chemical fertilizers is very similar to that of salt, alum, and alkali noodles, and more protective measures should be taken to avoid Ingestion poisoning. If symptoms of poisoning occur during the use of chemical fertilizers, work should be stopped immediately and the clothes should be quickly replaced, cleaned and rested in time. Severe poisoning should also be promptly sent to the hospital for treatment.
