What should I do if benzene in decoration exceeds the standard? Comprehensive analysis of detection, management and preventive measures
In recent years, as people's awareness of the health of their living environment has increased, the issue of decoration pollution has attracted much attention. Benzene is a strong carcinogen, and long-term exposure may cause leukemia and other diseases. The following are solutions for excessive benzene in decoration, compiled based on hot topics on the Internet in the past 10 days.
1. The hazards and sources of excessive benzene

Benzene is a colorless, aromatic volatile organic compound, mainly derived from paints, adhesives, waterproofing materials, etc. in decoration materials. According to World Health Organization standards, indoor benzene concentration should be less than 0.09mg/m³.
| Common sources of benzene pollution | benzene release cycle |
|---|---|
| Paint/coating | 3-12 months |
| Artificial board | 1-3 years |
| Adhesive | 6-18 months |
2. 4 methods to detect excessive benzene levels
1.Professional organization testing: CMA certified laboratory, cost 300-800 yuan/site
2.Self-test box: Convenient but less accurate, price 50-200 yuan
3.Electronic detector: Real-time monitoring, regular calibration required
4.plant observation method: Abnormal withering of green plants may be a sign of pollution
| Detection method | Accuracy | Applicable scenarios |
|---|---|---|
| Professional testing | ★★★★★ | New house acceptance |
| Electronic detector | ★★★☆☆ | daily monitoring |
3. Five major measures to control excessive benzene levels
1.Source governance: Replace inferior building materials and choose environmentally friendly materials (see GB 18580-2017 standard)
2.physical adsorption: Place 1kg of activated carbon every 10㎡ and replace it every month
3.air purification:Choose a purifier with CADR value >300m³/h
4.Photocatalyst technology: Professional construction can degrade more than 90% of benzene series
5.Ventilation strategy: Open windows during high temperature periods and use industrial fans to accelerate ventilation
| Governance methods | Effective time | duration |
|---|---|---|
| High temperature ventilation | 3-7 days | Need to be continued |
| Photocatalyst | Instant | 2-3 years |
4. Three key points to prevent benzene from exceeding the standard
1.Before decoration:Select ENF grade (≤0.025mg/m³) plate
2.Under construction: Avoid painting in rainy days and control the amount of materials used
3.After check-in: Maintain ventilation for more than 6 hours a day in the first 3 months
5. References to recent hot cases
In September 2023, a certain brand of children's paint was exposed to benzene exceeding the standard, which triggered heated discussions. Tests showed that the product's benzene release amount reached 0.15mg/m³, exceeding the national standard by 66%. Experts recommend paying attention to:
- View the Ten Ring Certification
- Request recent inspection reports
- Prefer water-based paint
Summary:Faced with the problem of excessive benzene in decoration, a three-in-one solution of "detection-treatment-prevention" should be adopted. We are especially reminded that families with pregnant women and children should leave the property vacant for at least 6 months before moving in. If necessary, professional air treatment services can be considered.
