The elementary flows are characterised with the help of compartments
and subcompartments. Pollutants are emitted to
the compartments of air, water, and soil. Furthermore, it is
specified (with subcompartments) whether an air pollutant,
for instance, is emitted to highly populated area, to a low
populated area or to lower stratosphere / upper troposphere
or to an unknown environment (unspecified). For water
pollutants the subcompartments of river, lake, ground water
and ocean are distinguished. For some subcategories
(emissions to air, low population density, and emissions to
groundwater) a temporal differentiation has been introduced.
Emissions from landfills take place over a long time period
after the waste placement. Emissions which take place 100
and more years after waste placement are named 'long-term'.
Resources such as minerals, and primary energy resources,
gases (e.g. CO2, nitrogen), and land transformation and occupation
are attributed to the category 'resource'.
