Carbon Monoxide Flashcards
0
Q
Fate
A
O.2 years in atmosphere
1
Q
Sources
A
Incomplete combustion, man made emissions, CH4, natural, transport,static power generation, process loses
2
Q
Rate of generation and abundance
A
Suggests rapid rate of destruction
3
Q
Rate of destruction?
A
In the low stratosphere OH- + CO to CO2 + H
4
Q
CO destroyed
A
On Earth surface, biological mechanisms, fungi and plants, rate of destruction same day/ night
5
Q
Effects
A
Animal respiratory system (hAemoglobin as O2 transporter)
6
Q
CO affinity
A
Co-ordination position, occupied by O2 is 200X greater
7
Q
Low partial pressure
A
CO displaces O2 from oxyhemoglobin (HbO2) to carboxyhaemoglobin (HbCO). HbO2 + CO to HbCO + O2
8
Q
Transport
A
Impaired O2 from lungs to tissues, 5% HbCO in blood
9
Q
Control
A
Mainly centered on motor vehicle exhaust
