How much does the indoor formaldehyde data exceed the standard? Is formaldehyde harmful? This hotel has just been renovated. I hope you can give me some advice, in addition to formaldehyde!

According to the national standard, the indoor formaldehyde concentration exceeds 0. 10 mg per cubic meter. If the decoration is just finished, there will still be chemical pollutants such as benzene, toluene, xylene and TVOC. Formaldehyde is a colorless and irritating gas. If formaldehyde exceeds the standard, it will affect people's upper respiratory tract. Obviously, I feel uncomfortable in my throat, and then I will have symptoms such as dizziness and nausea. Just after the renovation, it is suggested to choose a formal management company, and you can choose Harbin Ji Hong Environmental Protection.
