Question

A. Hydrogen sulfide
B. Sulfur
C. Hydrogen cyanide
D. Arsenic substances

Answer 1

Pollutants are the harmful substances that contaminate the environment. Pollutants have an adverse effect on plants and animals. Different pollutants have different physiological effects.

Complete step by step answer: Different pollutants cause different effects on an organism when exposed. Let us look at all the options that are given to us one by one.
-Hydrogen sulfide: Hydrogen sulfide is exposed to humans via inhalation, skin, or eye contact. It causes eye irritation and throat irritation, i.e., a burning sensation in the eyes and throat. It also causes nausea or vomiting. The burning sensation is usually throughout the respiratory tract. If a person is exposed to acute concentrations of hydrogen sulfide then headache, delirium, keratoconjunctivitis can also occur.
-Sulfur: The toxicity of sulfur to humans is quite low as compared to other pollutants. However, excessive exposure to sulfur can cause diarrhea or a burning sensation. It can also cause coughing and irritation in the skin and eyes.
-Hydrogen cyanide: Hydrogen cyanide can cause poisoning in the human body. It usually has whole-body or systemic effects. However, it affects those organs the most which are sensitive to low oxygen levels.
-Arsenic substances: Arsenic pollutants can cause irritated throat and lungs. It can also cause vomiting and nausea, and diarrhea, etc. Weakness, cramping, and skin rashes are other symptoms.
Thus, based on the above information we can conclude that hydrogen sulfide pollutant causes the burning sensation of the throat and eyes and vomiting sensation.
Hence, the correct answer is option (A).

Note: Hydrogen sulfide is produced by the putrefaction and the treatment of the sulfur-containing ores, in the refineries, chemical plants, and by the burning bituminous fuels. It is a highly flammable and toxic gas. In plants, hydrogen sulfide causes defoliation and mottled chlorosis. It also decolorizes the paints of the buildings.
