Does high temperature help formaldehyde volatilize?

High temperature is conducive to the volatilization of formaldehyde.

High temperature weather directly causes indoor formaldehyde release to be 20% to 30% higher than usual; for every 1°C increase in room temperature, formaldehyde volatilized from wooden furniture and floors will increase the formaldehyde content in the indoor air. The concentration increases by 0.15-0.37 times.

An experiment shows that when the room temperature rises to 30°C and the indoor relative humidity is 45%, the formaldehyde release concentration in the air is 0.223 mg/cubic meter, exceeding the national "Indoor Air Quality Standard" 2.23 times.

When the room temperature rises to 34°C and the relative humidity is 50%, the formaldehyde release concentration exceeds the standard by 5.53 times. In this environment, people feel as if they are in a closed room sprayed with pesticides, feeling stinging eyes and itchy throats.

Extended information:

Exceeding the standard of formaldehyde has three main serious hazards:

1. Sensitization: Direct skin contact with formaldehyde can cause allergic dermatitis and stains. , necrosis, bronchial asthma can be induced when inhaling high concentrations of formaldehyde.

2. Irritation: The main hazard of formaldehyde is the irritation to the skin and mucous membranes. Formaldehyde is a plasma toxic substance that can bind to proteins. When inhaled at high concentrations, severe respiratory tract irritation, edema, and eye problems may occur. Irritation, headache.

3. Mutagenic effect: High concentrations of formaldehyde are also a genotoxic substance. When experimental animals inhale high concentrations in the laboratory, nasopharyngeal tumors can be caused.
