摘要： 2009年12月14日—28日采集了新疆农业大学校园PM₁₀和PM_2.5样品，分析了重金属Cd的形态和风险指数。该采样点在冬季采暖期间PM₁₀及PM_2.5污染非常严重，PM₁₀和PM_2.5中Cd的含量分别为3.642和1.964 ng·m^-3，均以残渣态为主，但PM_2.5中Cd的生物有效性高于PM₁₀中Cd的生物有效性。PM₁₀中Cd的致癌风险为6.56×10^-6，而PM_2.5中Cd的致癌风险为3.46×10^-6，均处于可接受的风险水平。

Abstract：PM_2.5 and PM₁₀ samples were collected on campus of Xinjiang Agricultural University during Dec. 14—28, 2009, and the speciation of Cd in PM₁₀ and PM_2.5 and its health risk index was analyzed. The results showed that the pollution caused by PM₁₀ and PM_2.5 was severe here during the heating period; Cd in PM₁₀ and PM_2.5 was of concentration 3.642 and 1.964 ng·m^-3 respectively, mainly in the form of residue; however, Cd in PM_2.5 had a higher bioavailability than that in PM₁₀. The carcinogenic risk of Cd in PM₁₀ and PM_2.5 was 6.56×10^-6 and 3.46×10^-6 respectively, which were both acceptable.

Key words：PM₁₀;PM_2.5;Cd;Speciation analysis;Bioavailability
