Polychlorinated Biphenyls is a group of toxic compounds that were used as additives in many industrial applications in 20th century. Although banned for many years, they are still present in the environment and are released easily to the air from different states of matter. In our project, we focused on testing efficiency of one filer material that is widely used for PCB remediation, Activated Carbon. We built a system including an AC filter column and PCB source, and through set of extractions and GC-MS analysis, measured capacity of given material. Our extraction method turned out being ineffective for particular samples, but we proved that Activated Carbon decreases PCB concentration in the air (comparing input/output values) to level considered safe by health organisations around the world.
