Baking of semi-finished graphite products in a tunnel furnace is the source of many air pollutants present in both the gaseous and solid phases. The goal of this study was to assess emission rates into the air of the substances such as: CO, NOx, SO2, H2S, CH4, aliphatic hydrocarbons C1-C6, BTEX, total dust, tar substances and PAHs. The research showed a small time-dependence of the emission rates for the majority of the substances analysed. Concentrations of the analysed substances in exhaust gases were in the majority of cases at a low level, except for BTEX and PAHs.
