Global Scale Atmospheric Pollution Flashcards
Volume mixing ratio
(no. molecules of substance)/(no. molecules of air)
Mass Mixing ratio
= VMR * (molecular mass of substance)/(molecular mass of dry air)
Concentration
= MMR * air density
Air density
= P/R(dry air) * T
Environmental issues from air pollution
Acid desposition
Eutrophication
Ozone depletion
Acid Rain
Compare the impact and formation of NOx and SOx
SOx from fossil fuel burning
NOx from fossil fuel and transport
Cause and effects of eutrophication
NOx and NH3 from agriculture
Detrimental to biodiversity
Benefits generalists
Mechanisms of Climate Change
Human activity increases temp
Aerosols cool
CFCs, N2O, GHG - trap outgoing heat
Impacts of Air pollution on human health
7 million die annually
loss of life length
increased risk of disease (heart, lung, stoke, pulmonary disease)
impact of size of PM on effect
size of PM is important to potency
bigger generally more toxic
