  2. Sifat CO dan CO2 :

  3. Sumber CO Aktivitas alam • Oksidasi metana • Samudra/Lautan • Anthropogenic ( Aktivitas manusia ) • Transportasi • Pembakaran bahan bakar kendaraan • Proses industri • Pembuangan limbah

  4. Pembentukan CO • Pembakaran karbon yang tidak sempurna • 2C + O2 2CO • 2CO +  2CO2 • Reaksi antara CO2 dengan material yang mengandung karbon pada temperatur tinggi • CO2 + C  CO • Disosiasi CO2 pada temperatur yang tinggi • CO2 CO + O

  5. Dampak CO • Terhadap tumbuhan • Inhibisi fiksasi nitrogen • Terhadap manusia • Reaksi dengan haemoglobin (menghasilkan HbCO) secara irreversibel  mengganggu sistem transportasi oksigen.

  6. CO2 • Sumber CO2 : -Oksidasi dan pembakaran sempurna -Konversi CO oleh radikal hidroksil (OH-) -Respirasi makhluk hidup • Dampak CO2 : -Efek rumah kaca (green house effect)  perubahan cuaca -Killer gas

  7. CO2 in the atmosfer Respirasi Photosyntesis Combustion Precipitation Ocean Natural surfase mixing combustion Plants,Plants Fossil fuelsDissolved CO2 Volcanoes, animals, forest fires soils
