POP 21
Persistent Organic Pollutants Do not degrade in environment Very negative health effects
PCB
In plastics, adhesives, paints Make them malleable and flame retardant (can’t be oxidised) Forever chemical
DDT
Organochloride insecticide/ pesticides - Used to kill malaria mosquitoes in bogs - causes to spasm until death
VOC
Volatile Organic Compounds Solvents and fuel
PAN
HC + O2 + NO2 + UV -> CH3COOONO2 • Secondary pollutant in photochemical smog • more stable than O3 (ozone) so more transboundary • product of air pollutant reacting with sunlight • irritates eye glands, toxic and potent Vehicle emissions, tobacco, fossil fuel combustion
PM 2.5 ųm
Particulate matter of 2.5 micrometers - inhale-able and sits in bottom of lungs or gaseous exchange into blood stream
CFC
Chlorofluorocarbons Ozone depleting substances
CH4 SO2
Methane Sulfur dioxide
NVZ
Nitrate Vulnerable Zones Where aquifers exposed at surface so can easily become contaminated
LRTAP
Long Range Transboundary Air Pollutant
