In some cases additional information on major industrial stacks ('point sources') is available.

He closed the shutters on a view of wet streets, dark faces, industrial stacks, sour air.

However, while big industrial stacks are responsible for almost half of the mercury released into the environment each year, they are not the only sources.

Consequently, industrial stacks above about 150 metres or even 100 metres may contribute little pollution to smog locally.

Industrial Stack: ?

All around them, industrial stacks loomed overhead, spewing gaseous and particulate filth into the mustard-colored sky.

In 1974 he discovered and demonstrated how to collect and prevent carbon emissions from fossil fueled industrial stacks and internal combustion engines.

About one-third of the nation's oil is refined along the Texas Gulf Coast, an area covered with massive plants, mazes of pipes and towering industrial stacks.

Guidance on using an Alternative Method (AM) for measuring emissions of sulphur dioxide (SO2) from industrial stacks and flues.

Guidance on using manual extractive Fourier Transform Infrared (FTIR) spectroscopic instruments to measure emissions of pollutants from industrial stacks.

More recently a family of instruments based on near-infrared laser diodes have been developed that can make remote-sensing measurements of a number of pollutants in ambient air and industrial stacks.

If this inversion is only 100-300 metres deep, tall industrial stacks may release their emissions above the inversion, or the emissions may penetrate the inversion because they have great buoyancy due to high temperatures and fast exit velocities.
