Some metals and polycyclic aromatic hydrocarbons in fugitive PM10 emissions from the coking process

Coke oven batteries significantly contribute to fugitive emission of dust (particulate matter, PM) from the coking process. The dust contains harmful substances many of which such as heavy metals and polycyclic aromatic hydrocarbons (PAH), although mentioned in the Pollution Release and Transfer Registers (PRTR), so far have not been included into balances of emissions from hard coal coking. The goal of the presented work was to determine chemical composition of fugitive PM sampled on the battery roof. Three batteries in various technical conditions were examined for the PM emission. The results may provide information to help assessment of fugitive emissions from coking and for filling gaps in PRTR.
