Arsenic (As) is a ubiquitous carcinogen in the environment. Its bio-toxicity is significantly correlated with its chemical forms. In this study, As accumulation and speciation of PM₂.₅ was investigated in Jinan. The high PM₂.₅ levels fluctuated between 69.67 μg·m⁻³ and 211.25 μg·m⁻³ in winter, and ranged from 63.46 μg·m⁻³ to 125.50 μg·m⁻³ in summer. The total As concentration of PM₂.₅ in winter and summer varied from 4.23 to 15.47 ng·m⁻³ and from 4.59 to 11.69 ng·m⁻³. As(V) accounted for 70~100% of the extractable speciation in the PM₂.₅ samples. Exposure levels of total As for the general public were 63.45~232.05 ng d⁻¹, and 68.85~175.35 ng d⁻¹ by inhalation in winter and summer. The mean of cancer risk (CR) of As in PM₂.₅ for winter and summer were 7.30×10⁻⁶±0.89×10⁻⁶ and 5.26×10⁻⁶±0.58×10⁻⁶, respectively.
