The hub of water transportation in Seattle, known as the Puget Sound, is now producing less air pollution than ever. The Seattle Times reports that five years ago, scientists discovered that approximately one-third of the air pollution around the metro area was linked to bay traffic from tugs, ferry boats, oceangoing vessels, trucks, trains and forklifts all operating out of the Puget Sound.
Now, thanks to the regulations put in place by city officials and state and federal government, air quality has improved in the greater Seattle area.
"Federal regulations have helped, but we set goals to go way beyond that and we are," Stephanie Jones Stebbins, director of seaport environmental planning at the Port of Seattle, told the news source.
Toxic exhaust levels from heavy trucks is down more than 50 percent, exhaust from trains is down 25 percent and pollution levels from oceangoing ships is down 16 percent, according to the news source.
Decreases in air pollution levels will improve the quality of life of locals. However, with the amount of traffic coming through the Puget Sound, there is no current way to completely eradicate air pollution. By purchasing a home air purifier a Seattle resident can protect himself or herself from the damaging effects of air pollution.
