◉ Introduction to Indoor Air Testing
Indoor air refers to the air inside a building consisting of 6 faces.
Indoor air detection is the collection and detection of indoor air, and the determination of the types and concentrations of pollutants in the indoor air to determine the harmful gases and air quality in the indoor air.
Some decoration materials, paints, glues, etc. used in homes, commercial buildings, offices, etc. after new decoration and new furniture will produce some harmful irritating gases, such as: formaldehyde, benzene, ammonia, TVOC (volatile organic compounds) and the radioactive gas radon. For people who live and work indoors for a long time, it has considerable health hazards. These substances will slowly erode our body, causing lung cancer, leukemia, cancer and other diseases. Through scientific testing, it is possible to know whether the living room and office meet the relevant standards, so as to avoid the risk of environmental pollution.
For newly built civil construction projects, according to GB50325 "Code for Indoor Environmental Pollution Control of Civil Construction Projects" formulated by the Ministry of Construction of the People's Republic of China, from July 1, 2002, "all new construction, reconstruction and expansion of civil construction projects must be checked and accepted. Indoor environmental pollution concentration inspection, the inspection results must meet the national mandatory requirements.” All projects that fail to pass the inspection shall not be completed, and the management agency shall not allow the filing requirements.
