APES Unit 7 Review

pollutants that are released directly into the lower atmosphere.

pollutants that are formed by the combination of primary pollutants in the atmosphere.

carbon dioxide, sulfur dioxide, toxic metals and particulates

nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter

nitrogen dioxides lead to the production of ozone, formation of photochemical smog and convert to nitric acid in the atmosphere, causing acid rain

(SOx) Primary source is coal burning. Primary and secondary effects include acid deposition, respiratory irritation, plant damage. Reduction methods include: scrubbers, burn low sulfur fuel.

(NOx) Major source is auto exhaust. Primary and secondary effects include acidification of lakes, respiratory irritation, leads to smog and ozone. Reduced using catalytic converters.

sulfur dioxide

the Environmental Protection Agency (EPA) regulated the use of lead, particularly in fuels, which dramatically decreased the amount of lead in the atmosphere

automobile exhaust as well as burning of wood and coal

non-moving sources of pollution, such as factories.

pollution sources that are mobile, such as cars

Pollutants discharged from a single identifiable location (e.g., pipes, ditches, channels, sewers, tunnels, containers of various types).

pollution that does not have a specific point of release, open,loop recycling,when materials are reused to form new products.

pollutants judged to pose especially great threats to human health (carbon monoxide, sulfur dioxide, nitrogen dioxide, tropospheric ozone, particulate matter and lead)
