ABSTRACT
When soil or water becomes contaminated by and with pollutants, we have little dif-culty in understanding the need for the procedures and technology typically used to remediate the pollution. Polluted air, however, presents problems that soil and water do not. How do we clean up air once it has become polluted? Do we simply turn on a humongous air-purifying machine and let it do its work? Of course not. In air pollution remediation, we do not scoop the pollutants out of the atmospheric air and clean them. Instead, air pollution remediation is brought about through the use of air pollution prevention techniques. In other words, the technology we principally use today works to remove pollutants from air before it is discharged to the atmosphere (an end-of-the-pipe technique). We simply clean the polluted air before we discharge it-cleaning wholesale after discharge into the atmosphere is beyond the ability of present-day technology.
