NILU has conducted measurements, calculations, evaluations and impact assessments for different kinds of industries since the institute was first established in 1969.
Depending on the industrial activity, emissions to air will contain different types of contamination. Oil and gas production will, for example, result in emissions of nitrogen oxides (NOx), sulphur dioxide (SO2), particulate matter (soot), hydrocarbons (such as benzene and toluene) and polycyclic aromatic hydrocarbons, called PAHs. Metallurgical industries and smelting plants will emit the metals that are produced, but also substances such as NOx, SO2 and dust particles.
