Environment and Ecology (Easy) Pollution

Consider the following pollutants:

1. Carbon Monoxide (CO)

2. Oxides of nitrogen (NOX)

3. Suspended Particulate Matter (SPM)

4. Unburnt hydrocarbons

Which of the pollutants given above are released from vehicular emissions?

1, 2 and 3 only

2 and 3 only

1 and 4 only

1, 2, 3 and 4

Vehicles are mainly responsible for more than 80 per cent of total air pollution.

The major pollutants released from automobiles, locomotives, aircraft, etc., include Carbon Monoxide (CO), Unburnt hydrocarbons and nitrogen monoxide, nitrogen dioxide, suspended particulate matter emissions.
In metropolitan cities, vehicular exhausts account for most of the CO, hydrocarbons, oxides, and suspended particulate matter emissions. Hence Option (d) is correct.
