同位素比值法分子式：CAS号：性质：根据环境物质中元素的同位素比值，来判别其来源或形成过程的方法。不同来源或形成过程的环境化学物质，所含某种元素的同位素量(或称丰度)是不同的。根据元素同位素的比值，可用来推断其不同来源或其不同的形成(如一次排放物，还是二次生成物)。如用硫同位素34S和32S在大气颗粒物中的比值，与烟囱排出的颗粒物样品中硫同位素的比值进行对照比较，可以判明大气中的颗粒物是否与烟囱中的一样(即是否由它排放的)，抑或是二次颗粒物(化学反应生成的硫酸盐，SO42-)。研究结果表明，城市中大气颗粒物中的硫酸盐有20％～30％是一次颗粒物。又如根据氧的同位素18O和16O的比值，也可区别一次还是二次颗粒物。
