    Abstract This is the first study reporting the presence of six phthalic acid esters (PAEs) in 45 composite soil and road dust samples collected in the urban zone of Tianjin, China. Three sample types (one soil and two road dust) were collected from the city parks. Soil samples (SI) were obtained from inside the park, road dust samples (RDI) were gathered from inside the park roads and the others (RDA) from roads surrounding parks. The range of concentrations of ∑ 6 PAEs in SI, RDI and RDA were 0.07–0.92μgg −1 , 0.42–6.32μgg −1 and 0.40–7.54μgg −1 , respectively. The highest SI ∑ 6 PAEs concentration (0.92μgg −1 in The People's Park) was 13 times higher than that of the lowest content (0.07μgg −1 in XiLiu Park). Furthermore, the spatial distribution of PAEs in RDI showed higher contents in the Nankai and Hexi districts. PAEs concentrations in different types of roads displayed significant differences (P sub-arterial road > branch road. The results of nonparametric tests on ∑ 6 PAEs revealed significant differences between every two different sample types (P n BP and DEHP were the primary contaminating compounds in all sample types. The PCA results showed cosmetics and personal care products were important sources of PAEs in SI, and plasticizers were the key sources of PAEs in RDI and RDA. Highlights PAEs levels in road dust and soils in and around parks were studied in the city of Tianjin, China. Road dust exhibited higher PAEs concentrations. The PAEs contents in arterial roads are greater than those of sub-arterial and branch roads. The results of PCA showed that the sources of PAEs in soil and road dust were different.
