Which one of the following is an extremely short lived and unstable air/water pollutant?

Correct option is B

Volatile Organic Compounds (VOCs) are short-lived and unstable pollutants. They evaporate easily at room temperature and do not persist long in the environment. VOCs are typically found in products like paints, solvents, and gasoline, and they can contribute to smog formation when they react with other atmospheric components.
Information Booster:
1. Volatile Organic Compounds (VOCs) are organic chemicals that have a high vapor pressure at room temperature, leading to rapid evaporation and dispersal into the atmosphere. They break down quickly in the presence of sunlight and other atmospheric components, making them short-lived but potentially harmful in the short term.
2. VOCs are precursors to ground-level ozone and smog and can cause respiratory problems.
3. Common sources of VOCs include vehicle emissions, industrial processes, and household products like cleaning agents and paints.
Additional Information (Incorrect Explanation):
· (a) SMOG: Smog is a mixture of pollutants, including ground-level ozone and particulate matter. It is not a specific pollutant but rather a result of the reaction of pollutants, including VOCs, under sunlight. It can persist for longer periods in certain conditions.
· (c) Persistent Organic Pollutants (POPs): POPs are stable, long-lasting pollutants that persist in the environment for extended periods and accumulate in living organisms, making them highly toxic over time.
· (d) Polycyclic Aromatic Hydrocarbons (PAHs): PAHs are stable organic compounds that are formed from incomplete combustion of fossil fuels. They tend to be more persistent in the environment compared to VOCs.
