Abstract: | PAHs are formed during the incomplete combustion of organic substances containing carbon and hydrogen and are one of the first
atmospheric pollutants identified as carcinogens. Most of the PAH environmental burden is found in the soil (95%). Soil samples
collected from different roadsides were analyzed for seven polycyclic aromatic hydrocarbons (PAHs). The quantitative and qualitative
analysis was carried out by UV Spectrophotometer. The individual PAH value ranged from 0.1 to 18.0 mg/kg. Phenenthrene and
Pyrene were found to be the most abundant compounds. Vehicle emissions are the principal source of PAH in the Roadside soils.
The highest concentration was found at site S2 (Hasthtnagri Roadside) which shows the highest traffic density. |
