Volatile organic compounds, commonly VOC said it is the first word VotatileorganicCompound three-letter abbreviation, but sometimes also used to represent the total volatile organic TVOC. TVOC in the air three kinds of organic pollutants (polycyclic aromatic hydrocarbons, volatile organic compounds and aldehydes) affecting some serious kind. VOC refers to a saturated vapor pressure at room temperature over 133.32pa organics childhood leukemia, its boiling point at 50 ℃ to 250 ℃, at room temperature can not be present in the form of evaporation of the air, its toxicity, irritation, carcinogenicity and special odor resistance, affects the skin and mucous membranes, acute damage to the human body. Main component of VOC's include: hydrocarbons, halogenated hydrocarbons, hydrocarbons and nitrogen oxygen hydrocarbons, comprising: Bailey row ┑, organic chloride, Freon series, organic ketones, amines, alcohols, ethers, esters, acids, and petroleum hydrocarbon compounds such as ammonia (NH3) is a colorless gas with a strong pungent odor, lighter than air (specific gravity 0.5) ammonia childhood leukemia, can feel the lowest concentration of 5.3ppm. Ammonia is an alkaline substance, skin contact has its corrosive effect Wo Si excited. Can not absorb the moisture in the skin tissue, the tissue protein denaturation, and saponification of fat tissue, damage the cell membrane structure. High solubility of ammonia, so the main animal or human upper respiratory tract irritation and corrosion, weakening the body's resistance to disease and immunity. Except when the corrosive effects of high concentrations prevention of childhood leukemia, but also by reflex cardiac arrest caused by trigeminal nerve endings and respiratory arrest. Usually in the form of ammonia gas is inhaled into the alveoli of ammonia, carbon dioxide in small part and the rest is absorbed into the blood, a small amount of ammonia can be with the sweat, urine or breath excreted. Ammonia is easily inhaled into the lungs through the alveoli into the blood after childhood leukemia TVOC, 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 associated with 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.
