The primary precursor of photochemical smog that can be metabolised by plants such as Juniparus and Pyrus, is
PAN
- ozone
nitrogen dioxide
- Carbon dioxide
- Sulphur dioxide
The Correct Option is A
Approach Solution - 1
When NOx and VOCs are released into the environment from a variety of sources, photochemical smog starts to develop. Ozone and peroxyacetyl nitrate (PAN), two secondary pollutants, are created when sunlight interacts with these pollutants and sets off a sequence of chemical reactions
The correct option is (A) : PAN
Approach Solution -2
Photochemical smog is formed by the action of sunlight on pollutants such as nitrogen oxides and volatile organic compounds. The primary pollutants react to form secondary pollutants, including ozone, PAN (peroxyacetyl nitrate), and aldehydes.
While nitrogen dioxide is a precursor to photochemical smog, PAN (peroxyacetyl nitrate) is a key component of photochemical smog that can be metabolized by certain plants like Juniparus and Pyrus.
PAN, in particular, are secondary pollutants and cause significant plant damage.
Therefore, the answer is PAN.
