AIR POLLUTION
Carbon Monoxide (CO)
-produced when cossil fuels are burnt without enough air/oxygen supply
-
poisonous-restricts binds to haemoglobins and restricts the ability to carry oxygen
around the body
↳ can cause death
Source : solutions :
↳ car emissions ↳ Catalytic converters (fitted into modern cars)
)
↳
turn the CO into Co , to reduce the amount Co released
of
Succur dioxide (SO2)
↳
Burning fossil cuels
↳
Comes from the succur impurities in cossil cyells
↳ When sulcur dioxide mixes with rain clouds , it forms dilute succuric acid
↳ this falls as acid rain
source :
Internal
↳ - power stations
combustion engines in cars
Effect of acid rain :
- causes lakes to become more acidic ↳ kills trees
>
↳
affects the lakes ecosystem ↳ the acid damages leaves & releases
↳ many organisms are sensitive to toxic substances into the Soil
changes in pH ↳ makes it hard for trees to take up
↳ many organisms can't survive in nutrients
acidic conditions (causing death (
THE GREENHOUSE EFFECT
Greenhouse gases trap energy crom the sun
1) the temperature of the Earth is a balance between the energy it gets from the Sun
and the energy it radiates back into the atmosphere
2) gases in the atmosphere typically absorb most of the heat that would normally
be radiated out into space & re-radiate it in all directions (inc. back to earth) .
This is the
↳ greenhouse effect
↳ needed because at night there would be nothing to keep energy in
,
3) greenhouse gases include 4) Humans are increasing the levels of greenhouse
:
↳ water vapour gases (especially COC
↳ CO2 4) Other are CFC's & Nitrous Oxide
↳ methane this enhances the greenhouse
↳
gases
5) global Warming : the Earth heating up
↳ a type of climate & causes other
change climate change (e g Changing rainfall
. .
patterns
↳ climate change leads to extreme weather
↳ rising sea-levels
↳ clooding due to ice caps melting
↳ could case habitat loss , affecting good webs & crop growth
Human Activity Produces Lots of Greenhouse Gases
1) CO2
Y carbon dioxide released through car exhausts ,
industrial processes burning,
fossil fuels etc
