Formaldehyde 74ug per cubic meter what does it mean to exceed the standard

"Formaldehyde 74ug per cubic meter" refers to the amount of formaldehyde in the air per cubic meter of 74 micrograms (ug).

According to the domestic standard, the limit of formaldehyde in the indoor air quality standard is milligram cubic meter, therefore, the formaldehyde content of 74ug per cubic meter exceeds the domestic standard and can be considered to exceed the standard.

The formaldehyde value is in accordance with the indoor air quality standard.

GB T 18883-2002 2003-03-01 implementation), the formaldehyde content is per 1mg m of the 1h average value does not exceed . Therefore, from the numerical point of view, there is no exceedance, only the value measured by the professional formaldehyde detector is more accurate and worthy of reference. For this kind of professional instrument, it is also generally at the level of more than 10,000 yuan, which is too expensive for ordinary families, and the formaldehyde detector purchased online will basically be affected by temperature, humidity and other conditions and produce deviations, in fact, it does not have reference value, it is recommended that you find a CMA testing agency to detect better, if the formaldehyde content is higher, you can use Diallin spray.

Ventilation activated carbon.

What is the formaldehyde reading 349ug cube.

Dear, hello, I am happy to serve you, the answer is as follows: formaldehyde reading 349ug cubic is the conversion of the left and right cubic concentrations containing units ppm and mg m3, calculated according to the following formula: (1) m is the molecular weight of the source early gas; (2) p is the gas pressure; (3) t is the temperature of the gas, (4) ppm is the volume, (5) ppm is the concentration, and the formula is simplified: mass concentration (mg m3) = m ppm The mass of formaldehyde molecule is calculated according to the standard

That's what you want.

The indoor formaldehyde concentration is exceeded.

Formaldehyde detection refers to the quantitative detection of formaldehyde contained in air, water, food, clothing, plates, leather, etc. through specific methods or instruments. White or non-iron clothing, especially some jeans, pants that advertise 100% wrinkle and shrink resistance, or cotton non-iron shirts that are shaped with glyoxal resin, contain formaldehyde.

Formaldehyde is colorless and odorless, but people who exceed the standard will react on their own: their eyes are uncomfortable and their throats are tight. Formaldehyde and harmful gases may also be the cause of other diseases, which should not be underestimated.

If a pregnant woman is pregnant, it will also lead to miscarriage, stillbirth, fetal development malformation, etc., which is very harmful to the elderly and children. Find a professional to test it. If it exceeds the standard so severely, it will naturally volatilize and cannot be lived in for a year or two.
