Long-term living in polluted air can cause respiratory dysfunction, respiratory symptoms worsened Huangshan formaldehyde detection governance agency, some will lead to chronic bronchitis, bronchial asthma, emphysema and other diseases, lung cancer, nasopharyngeal cancer prevalence will increase. According to statistics, the global air pollution cause acute respiratory infections per year claimed the lives of about 4 million children. Domestic and international surveys show that respiratory tract infections are the most common diseases of humans, the symptoms can be life-threatening until the latent infection. Indoor air pollutants can be divided into respirable particulate matter, but also a major carrier carcinogenic chemical contaminants and radioactive substances. Biologically active particles bacteria, viruses, pollen, etc., is the culprit of most respiratory infections and allergic diseases. In indoor environments, especially in poorly ventilated, overcrowded environment, some pathogenic microorganisms easily spread through the air, so susceptible to infection. Some common viruses, bacterial diseases such as influenza, measles, tuberculosis and other respiratory diseases are spread by air in the room. SARS virus outbreak fact also indicates that indoor biological pollution should not be underestimated! Disease Prevention and Control Center, Shandong Province, monitoring and evaluation of public health Fan Ling said: many indoor air pollutants are irritating gases, such as sulfur dioxide, benzene and formaldehyde. These substances can irritate the eyes, nose, throat and skin Huangshan addition to formaldehyde, causing tears, coughing, sneezing and other symptoms. In particular, has a strong carcinogenic formaldehyde and cancer-promoting effect. In order to prove that a low concentration of ammonia in the air and the effects on human health hazards of formaldehyde detection Huangshan CMA certification, experts monitoring the workers working in contact with 3-13 mg / m concentration of ammonia in the indoor environment, which lasted eight hours, 10 people per group, compared with healthy people do not touch ammonia, find contact 13 mg / cubic meter man, urinary urea and ammonia levels were increased, blood urea increased significantly.   addition, farm sheds ammonia experts provided information on the impact of the chicken can also be used as a reference. Due to a large amount of ammonia in chicken, so when ammonia in the air sheds up to 20ppm (equivalent to 15.2 mg / m3), continued for more than six weeks, it will cause the chicken lung congestion, edema, decreased appetite chickens, egg production force reduction, disease susceptibility; Ruda 50ppm, laryngeal edema occurred a few days later chicken, necrotizing bronchitis, pulmonary hemorrhage, respiratory rate decreased, and the emergence of death. Therefore, the concentration of ammonia in the air sheds require control below 20ppm. We can see that the low concentration of ammonia in indoor air pollution on human health hazards.  ammonia easily after being inhaled into the lungs through the alveoli into the blood, combined with hemoglobin, oxygen transport function destruction. After the short-term inhalation of ammonia may be tears, sore throat, hoarseness, cough, sputum with bloodshot eyes, chest tightness, difficulty breathing, may be accompanied by dizziness, headache, nausea, vomiting, fatigue, severe pulmonary edema can occur, for adults respiratory distress syndrome, respiratory tract irritation may occur simultaneously. So the basic material damage to tissue deep and serious than acidic substances.
