A pollutant causing a burning sensation in the throat and eyes, along with feeling of vomiting is

• A. Hydrogen sulphide
• B. Sulphur dioxide
• C. Hydrogen cyanide
• D. Arsenic.

Answer 1

The correct option is A

Hydrogen sulphide

Hydrogen sulphide is a colourless gas with the characteristic foul odour of rotten eggs. Hydrogen sulphide is found in coal pits, volcanic gases, natural gas wells, sulphur springs and decaying organic matter containing sulphur. Potential large emitters of hydrogen sulphide are electric power plants (burning coal or fuel oil containing sulphur), oil and gas extraction operations, oil refineries, pulp and paper mills, sewage treatment plants, large pig farms and other confined animal feeding operations. Following too much exposure to these, there could be headaches, dizziness, and nausea. Repeated exposure may cause burning sensation of throat and eyes, headaches, anorexia, insomnia, paralysis, meningitis, psychic troubles, slowed heart rate, bronchitis and a grey-green line on the gums.
