- | In the GB 2019 Tier 2 emission factors for bitumen blowing are presented for NMVOC, TSP, Cd, As, Cr, Ni, Se and PAH. As the emission factors for TSP and heavy metals are unreferenced and based on US plants before 1980 they seem to be unsuitable to represent national conditions. That’s why own emission factors are used. | + | In the GB 2019 < |
