Question

There are certain raw materials that cause a lot of air pollution but they should be substituted with other raw materials which cause less pollution.

• A. True
• B. False

Answer 1

The correct option is A True

If the use of a particular raw material results in air pollution, then it should be substituted by another purer grade raw material which reduces the formation of pollutants.

For example

1. Low sulphur fuel which has less pollution potential can be used as an alter­native to high Sulphur fuels.

2. Comparatively more refined liquid petroleum gas (LPG) or liquefied natu­ral gas (LNG) can be used instead of traditional high contaminant fuels such as coal.
