Which Of The Following Is A Secondary Pollutant?

When you breathe in air, it’s not just CO2 that makes up for about 50% of the volume. There are also secondary pollutants like ozone and NO2 that come from things like hydrocarbons (HC) or nitric oxides (NOx). Ozone is a type of oxygen with extra potency which can be formed when two different molecules combine under sunny skies; its presence has been linked to asthma attacks among others health problems since exposure causes lung irritation on contact. Another example would acid rain – this occurs due to certain types water reacting naturally occurring emissions such as sulfur dioxide gas + HCl.
