Haze is caused when sunlight encounters tiny pollution particles in the air. Haze
obscures the clarity, color, texture, and form of what we see. Some haze-causing
pollutants (mostly fine particles) are directly emitted to the atmosphere by sources such
as power plants, industrial facilities, trucks and automobiles, and construction activities.
Others are formed when gases emitted to the air (such as sulfur dioxide and nitrogen
oxides) form particles as they are carried downwind. For more information on haze, visit
