Criteria Air Contaminants (CACs) include carbon
monoxide (CO), particulate matter (coarse and
fine), volatile organic compounds (VOCs), sulphur dioxide (SO2) and
nitrogen oxides (NOX).
The development of an emissions
inventory is a labour-intensive procedure requiring a significant level of
effort and commitment of time and resources. The end-uses for emission
inventories may be summarized as follows:
|
Policy Planning
and Development
|
Defining emission reduction objectives
at the regional, national or global scale, and calculating emission abatement
costs and benefits.
|
|
Regulatory
Compliance
|
Demonstrating compliance with regional,
national or international emission reduction objectives, policies or
agreements.
|
|
Effects
and Consequences
|
Assessing the potential and/or
detectable impacts on human health, ecological systems, and real or perceived
nuisance to the general public.
|
|
Atmospheric
Modelling
|
Data input to transport, transformation,
deposition, source apportionment and receptor modelling in support of policy
planning & development. Verification of the benefits of abatement
strategies and applied scientific research.
|
|
Quality
Assurance and Quality Control
|
Comparisons between concentrations
predicted from estimated emissions and observed ambient
concentrations.
