Classification of organic substances
Category Substance
O1 many components (e.g. acetaldehyde, acroleine, acrylic acid, amino benzene/ethane/methane,
anilin, anthracene, bisphenol A, caprolactam, 1,2-dichlorobenzene,
dichlorophenols, formaldehyde, methylamine, nitro-monocyclic-aromatics, organotins, phenol,
pyridine, tetrachloromethane, trichlormethane).
O2 many components (e.g. 1,3/4-dichlorobenzene, cumene, ethyl-benzene, monochlorobenzene,
styrene, tetrachloroethene, toluene, 1,1,1-trichloroethane, trichlorethene, xylenes)
O3 many components (e.g. dichloromethane, many alcohols, alkanes and ketones)
Inorganic substances
Distinction is made between gaseous and solid inorganics (gI and sI respectively). The reason
for doing so is that the techniques that can be applied to reduce the emissions for gaseous and
solid components are different. The substances have been classified according to their ecotoxicity.
The standard for solid inorganics applies to the emission of the sum of the substances (so
called ‘summation rule’).
