The report found that changes in vehicle technology and population are the main factors affecting urban air quality impacts over the next two decades.

By 2030, the total amount of exhaust pollution from the tailpipes of cars and trucks is expected to reduce, despite strong growth in traffic volumes. This is because improved technology is entering the vehicle fleet faster than the rate of traffic growth.

For emissions that are linked to domestic and business activities, significant increases are expected due to the 45 per cent population growth projected for the Melbourne and Geelong areas between 2006 and 2030.

The key pollutants of concern in the future are particles and ozone. These pollutants develop in the air from many different sources, not just road traffic. Although we have less of these pollutants now in Melbourne compared with the 1980s, current levels are occasionally high enough to breach air quality standards. As our population grows, the overall impact of these pollutants is likely to increase. The good news is that for many other pollutants, including carbon monoxide, nitrogen dioxide and air toxic, levels are expected to reduce over time, giving us cleaner air to breathe. Computer animations (movies) have been prepared for some pollutants. Click on one of the links below to see how changes in emissions will affect air quality in the future.

We focus on Ultra-violet DOAS gas analyzer, Laser TDLAS gas analyzer, continuous emission monitoring system and etc, basically covering air pollution monitoring, metallurgical industries, chemical, refinery industries, cement, sulfur recovery, flue gas and other online monitoring needs. Our friendly and professional staff are always ready to provide technical support to our customers.
