Study on emission characteristics and health effects of volatile organic compounds in child seats

Abstract

This paper takes two mainstream child seats on the market as the research object, based on the test standard of volatile organic compounds (VOCs) and the objective odor test standard of components and parts assembly, and under 25°C standard condition, the emission concentration of VOCs and the odor objective level of the two seats were detected to understand the VOCs emission and odor performance of the child seats. Gas chromatography-mass spectrometry (GC-MS) was used to analyze the whole spectrum, and the odor threshold database was used to screen out the key odor components contributing to the odor in the car. According to the WHO-IARC to analyze the carcinogenicity of key odor contributing substances. The results show that the odor performance of the two types of child seats is in average level, and the objective odor intensity were 3.3 and 3.7. The emission of Formaldehyde, Acetaldehyde and Benzene of the two seats were significantly lower than the average value of the seat industry, while dimethylbenzene and Styrene were higher than the industry average. In addition, Benzothiazole, 2,6-Ditert-butyl-4-methyl phenol, Isooctanoic Acid, Cyclohexyl Isothiocyanate, etc. The above-mentioned high-risk odorants are harmful to health, which should be paid more attention by manufacturers.
