Abstract Organic ultraviolet absorbents (UVAs) are widely found in the environment. However, little is known about UVA distributions in street dust and the risks they pose to human health. We determined the concentrations of 12 UVAs in street dust from cultural, residential, traffic, and industrial areas in Hefei, China. 4-Methylbenzylidene camphor was not detected in the street dust samples. The total concentration range of the 11 other UVAs (Σ11UVAs) in the street dust samples was 6.42–94.2 ng/g. Octocrylene was the dominant UVA, contributing 53.8 % of the Σ11UVA concentrations. The UVA concentrations were higher in dust from the industrial area than in dust from cultural, residential, and traffic areas. Source analysis was performed, and industrial activities and the use of cosmetics and personal care products were found to be the main sources of UVAs in street dust. The health risks posed to humans exposed to UVAs in street dust in Hefei were generally low. More research is required to improve our understanding of the health risks posed to humans exposed to UVAs through other pathways.
