Why Monitor the Environment?
Chemical Spill pollution
spills caused by
fires
explosions
leaks
damage to transport/storage
consequences
long term
if chemicals not contained
death or marine organisms
April 2017 Brisbane River
22,000L firefighting foam
monitoring
determine extent of contamination
health of population
Fertiliser Pollution
problem
fertilsers washed off gardens/fields
make way to lakes/rivers
eutrophication
addition of phosphates and nitrates in waterways
algae experiences fast growth
due to fertilisers
form layer at top of water
preventing sun entering water
plants unable to photosynthesise
lack of oxygen in water
animals die

Importance of Monitoring Waterways/Fertiliser use
prevent algae blooms
death of organisms
waterways filled with chemicals
through controlled use of fertilsers
Murray River
Ozone pollution
ozone
O3
found in stratosphere
20-25km above Earth's surface
essential
converts UV light into heat
UV - hazardous for human skin
Chlorofluorocarbons (CFCs)
previously used in deodorants + refrigerants
chemical analysis
destroying ozone layer
structure of CFCs
release Cl atoms into stratosphere
Cl + O3 -> ClO + O2
effects on the environment/resources
