Commercial delivery vans are used to transport goods in urban areas.
The exhaust emissions from three different delivery vans of similar engine size and load capacity were investigated:
Using the data in the table below and your own chemical knowledge, discuss and compare the environmental and health impacts of the emissions from these three vans.
| Delivery Van | Carbon monoxide (g/km) | Nitrogen oxides (g/km) | Carbon dioxide (g/km) | Particulates (g/km) |
|---|---|---|---|---|
| Van A (Older petrol, no catalytic converter) | 1.85 | 0.12 | 210 | 0.00 |
| Van B (Modern petrol, with catalytic converter) | 0.45 | 0.03 | 210 | 0.00 |
| Van C (Modern diesel) | 0.08 | 0.25 | 165 | 0.01 |
