In recent years, the decoration pollution harmful to health, has increased the morbidity and mortality to the worldwide population, due to the fact that the hazardous substance is contained in the building materials selected for newly built and rebuilt constructions contains  hazardous substance and exceed certain limits seriously. The poor quality of construction will lead to the indoor air pollution. When the toxic and harmful substances are found in the working and living environment, such as soluble heavy metals (lead, cadmium, chromium, mercury), free formaldehyde, formaldehyde, total volatile organic compounds(VOC), benzene, methylbenzene, xylene, ethylbenzene, vinyl chloride monomer, styrene, ammonia and radon, the adverse reaction will range from sore throat, chest distress, dizziness, diminution of vision, vesication and the like, to the damage of the immune system, blood disease, other serious diseases or even cancer. In order to prevent and control the indoor environmental pollution of the newly built, expanded or rebuilt civil architectures, the government has created relevant standards, i.e., the concentration of indoor environment pollutant must be supervised in accordance with the regulations during the acceptance check of civil architectures. 

With its professional equipment, scientific and technological talents, and advanced technology, we(Attestation of Global Compliance) provides enterprise units, social organizations and government sectors with professional and authoritative service of monitoring the ambient air.

"Code for Indoor Environmental Pollution Control of Civil Building Engineering" (GB50325-2006) 
"Code for Indoor Environmental Pollution Control of Civil Building Engineering" was implement by force in 2002, revised in 2006 and officially implemented on August 1, 2006. According to the regulations, when the construction project is completed, the construction unit shall check the indoor environmental quality according to the standard, and entrust the recognized testing organization to test the content index of indoor radon, formaldehyde, benzene, ammonia, total volatile organic compounds (TVOC) of the constructional engineering. The construction is not allowed to be put in use if the content index of indoor harmful substances does not match the standard, otherwise the current unit will be punished. 

"Technical requirement for environmental labeling products. Building decoration engineering." (HJ440-2008) Authorized by the Ministry of Environmental Protection, and has been implemented since September 1, 2008. It applies to the decoration engineering of newly built, expanded or rebuilt civil architectures. Compared to the requirements in GB50325, it places higher demands for the indoor air quality.

"Indoor air quality standard" (GB18883-2002) 
It specifies the indoor air quality parameters and test methods and applies to the residential and office buildings. Method of testing various parameters in the indoor air.
