apes unit 7 Flashcards
outcome of industrial smog and how is it formed
produces sulfuric acid, mixes with oxygen gas from coal
what forms when there is not enough oxygen to produce carbon dioxide
carbon monoxide
how does carbon monoxide release in atmosphere (two ways)
- volcanic activity
- burning of fossil fuels
effects of lead poisoning
- premature births, miscarriages, failure to produce hemoglobin
where is lead found
used in building construction, lead acid batteries for vehicles
how do nitrous oxides form
when nitrogen is in the presence of combustion
effects of nitrous oxides
ozone depletion
effects of tropospheric ozone
can cause asthma and bronchitis, harm lung function
where do sulfur dioxide emissions come from
- power stations
- oil refineries
- burning fossil fuels
sulfur dioxide + air moisture =
acid rain
how do PMx enter the atmosphere (give two natural and two human made)
natural:
- dust storms, fires
- burning fossil fuels, incineration of waste
how do PMx affect the environment (two specific examples)
- decrease nutrients in soil
- make lakes and streams more acidic
what are VOCs
volcanic organic compounds
how is photochemical smog produced
NOx reacts with VOCs to produce it
explain how thermal inversions occur
surface cools (so happens at night and stuff), heat from the day gets trapped above the new colder air which traps dust and increases concentration of it
key words for asbestos:
- insulating, fireproofing
indoor chemical linked to lung cancer
formaldehyde
pollutant found in RRRock formations beneath buildings
radon
what does a catalytic convertor do
converts toxic chemicals into less toxic form (carbon monoxide to carbon dioxide)
