Question

Which pollutant causes(a) Damage to neuron (b) Dryness in throat (c) Headache and blurred vision?

• A. Hydrocarbons
• B. Hydrogen sulphide
• C. Hydrogen fluoride
• D. Hydrogen cyanide

Answer 1

The correct option is D Hydrogen cyanide

Hydrogen cyanide stops the transport of oxygen around the body and may also cause sudden loss of consciousness, weakness, headache, confusion, nausea, vomiting, irritation and eye infections. People with sensitive kidneys, respiratory tract (air passages and lungs), skin or thyroid are more prone to hydrogen cyanide poisoning. Part of the reason why hydrogen cyanide is considered potentially more dangerous is that some individuals are unable to detect it by smell which creates damage to neurons.

So the correct answer is 'Hydrogen cyanide'.
