However, in this industrial age, even small businesses such as bakeries and dry cleaners contribute to the problem, as well as individuals using paint, ink and dye products.

In Los Angeles alone it has been estimated that in addition to automobiles, more than 60,000 stationary emission points contribute to the problem. This is in addition to the eight million automobiles and truck in Los Angeles basin (Brown, 1987).

Pesticides sprayed into the air by farm growers and other toxic chemicals used in the manufacturing sector are also a large part of the problem. An especially large part of the pollution
