Contribution of other human made sources to pollution
Region: Aotearoa - New Zealand
Description: Other human-made sources – such as aviation, forestry, and non-combustion industrial activities (eg grinding and crushing) – generally emit relatively small amounts of key air pollutants. Comparing their contribution to air pollution helps us understand the pressures they place on our air quality. Other human-made sources of air pollution include but are not limited to: - transport emissions from aviation, off-road motor vehicles, rail, and shipping transport activities - non-combustion emissions from industry, such as process emissions (eg milk driers) and activities that involve abrasive and mechanical processes (eg grinding and crushing) - agricultural and forestry activities, such as logging activities and agricultural burning.
