Scope

This standard applies to benzene and benzene compounds (benzene, toluene, ethylbenzene, p-xylene, o-xylene, m-xylene, isopropylbenzene, and styrene) in indoor air. It also applies to the determination of benzene and benzene compounds (benzene, toluene, ethylbenzene, p-xylene, o-xylene, m-xylene, isopropylbenzene, and styrene) in the atmosphere of residential areas. With the rapid development of society, ecological environment and sustainable development have become hot topics of great concern to us, especially the indoor air pollution problem closely related to our work and life, the harmfulness of which cannot be ignored. Because it has become a potential killer and is gradually affecting human health. Studies show that the organic pollutants that most harm human health and affect indoor air quality are formaldehyde, benzene, and benzene compounds. Nowadays, formaldehyde, as the "focused darling", has received widespread attention and many research reports, while benzene and benzene compounds, known as "aromatic killers", are often neglected. If people live in an environment with low concentrations of benzene and benzene compounds for a long time, they will experience neurological symptoms such as headaches, dizziness, numb fingers, and general weakness. In severe cases, they may experience hypoxia symptoms such as palpitations, chest tightness, shortness of breath, and vomiting. Determining the content of benzene and benzene compounds in indoor air is of great significance for detecting indoor air quality and protecting human health. At present, the detection of benzene and benzene compounds in indoor air in China uses gas chromatography analysis technology. Standard methods include GB/T 18883-2002 "Indoor Air Quality Standard", GB 11737-1989 "Hygienic Inspection Method for Benzene, Toluene, and Xylene in Atmosphere of Residential Areas by Gas Chromatography", HJ 583-2010 "Determination of Benzene Compounds in Ambient Air by Solid Adsorption/Thermal Desorption-Ga
