A

Clean Air Act of 1990

30

41
Q

“Grey-air” smog caused by the incomplete combustion of coal or oil when burned

A

A

Halocarbons

45
Q

Type of halo-carbon with only chlorine, fluorine, and hydrogen, were used as refrigerants, fire extinguishers, and propellants for aerosol spray cans, cleaners for electronics, and for making polystyrene foam. Phased out under Montreal Protocol because they are ozone depleting.

A

46
Q

Term used to describe the thinning of the ozone layer that occurs over Antarctica each year, as a result of ozone depleting services

A

Ozone Hole

47
Q

International treaty ratified in 1987 , nations agreed to restrict production of CFCs in order to halt ozone depletion

A

Montreal Protocol

48
Q

the setting of acidic or acid-forming pollutants from Earth’s surface
