The aromatic compounds present as particulates are :
Open in App
Solution
The correct option is D Polycyclic aromatic hydrocarbons
Particulate matter (PM) has become a major research issue receiving increasing attention because of its significant negative impact on human health.
Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds consisting of two or more fused aromatic rings.
PAHs originate mainly from anthropogenic processes, particularly from incomplete combustion of organic fuels. PAHs are distributed widely in the atmosphere.
Natural processes, such as volcanic eruptions and forest fires, also contribute to an ambient existence of PAHs. PAHs can be present in both particulate and gaseous phases, depending upon their volatility.
Therefore, option A is correct.
