APES Chapter 15 review

PM10 or PM2.5

-Combustion of coal, oil and diesel, and of biofuels such as manure and wood -agriculture, road construction, and other activities that mobilize sil, soot, and dust

CO

-incomplete combustion of any kind -malfunctioning exhaust systems and poorly ventilated cooking fires

NOx

All combustion in the atmosphere including fossil fuel combustion, wood, nd other biomass burning

a corrosive gas from burning coal often associated with industrial smog

SO2

All of the following are examples of primary air pollutants except a) sulfur dioxide b)carbon dioxide c)tropospheric ozone d)nitrogen oxide

Tropospheric ozone

O3

a secondary pollutant formed by the combination of sunlight, water, oxygen, VOCs, nd NOx

__________ is a catalyst and repeatedly breaks down ozone molecules

clorine

the EPA identifies all of the following as reasons for sick building syndrome except a)faulty ventilation systems b)emissions from carpets and furniture c)contamination from molds and pollen d)high levels of radon in the basement

emissions from carpets and furniture

incomplete natural gas combustion

the effects of acid deposition include all of the following except a)mobilization of metal ions from the soil into surface water b)increased numbers of salamanders in ponds and streams c)reduced food sources for aquatic organisms d)erosion of marble buildings and statues

increased numbers of salamanders in ponds and streams

SO2

is a result of combustion of fuels that contain sulfur, including coal, oil, and gasoline

ozone

The greatest emission of sulfur dioxide comes from a)on-road vehicles b)biofuels c)industrial processes d)power plants

power plants

two major factors involved in the conversion of primary pollutants into secondary pollutants are a)sunlight and water b)sulfates and sunlight c)water and volatile organics d)nitrogen oxides and sulfates

sunlight and water
