Formaldehyde has a strong irritant, at lower concentrations, the human eye has a spicy sensation, tearing, redness and swelling. Higher concentrations, they will feel choking, nausea and even difficulty breathing, choking. These "biochemical reaction" from the toxicity of formaldehyde. Formaldehyde is the smallest oxygenated organic compounds, having a higher reactivity, and may have -OH (hydroxyl group), - SH (thiol group), - molecular NH2 (amino) groups of the nucleophilic addition reaction, formaldehyde as final methylene (-CH2-) providers, two radicals react with these groups, so that the freedom of the molecular chains are crosslinked by formaldehyde up, lose their physiological functions. This is like our hands, each hand on behalf of one of the above groups Zongyang formaldehyde detection CMA certification, formaldehyde as an original freedom handcuffs handcuffed hands (even handcuffed one), it makes our hands lost their original function freely. In human cells, there are a lot of enzyme systems hydroxy, mercapto, amino, reaction occurs immediately after contact with formaldehyde, cytotoxicity, protein denaturation (formaldehyde sterilization ability is superior original from this reaction). From this "biochemical reaction" immediate results, that people feel unwell; in the long run, you can not rule out the potential carcinogenicity of formaldehyde have bloodshot eyes, headaches, upset, unable to stay in the bedroom to sleep: This is the Beijing University of Chemical Yang flower the price for the purchase of bedroom furniture in exchange for 6400 yuan a month. Later, through testing, found indoors six times more methanol than the standard. Human indoor activities, such as heating, cooking, indoor disinfection and so can cause contamination. In addition, office equipment and household appliances in use will produce noise, electromagnetic waves and bacteria and viruses and other microbial contamination. Large survey of people in Beijing Center for Disease Control and Prevention found that indoor air pollution, including chemical, physical, biological, radioactive substances into four categories of more than 50 species of Maple formaldehyde detection governance phone, which, formaldehyde, benzene and volatile organic matter exceeded 20 30 times Zongyang formaldehyde detection method of governance, the highest actually reached 40 times. We have to face this fact: every year the number of deaths caused by indoor air pollution has reached 11.1 million, which is about 304 people a day. China Interior Decoration Association Environmental Monitoring Center revealed that number, just a day is equivalent to the number of road accident deaths in the country.
