Zusammenfassung: | Tehran as the biggest city of Iran with a population of more than 10
millions has potentially high pollutant exposures of gas oil and
gasoline combustion from vehicles that are commuting in the highways
every day. The vehicle exhausts contain polycyclic aromatic
hydrocarbons, which are produced by incomplete combustion and can be
directly deposited in the environment. In the present study, the
presence of polycyclic aromatic hydrocarbons contamination in the
collected samples of a western highway in Tehran was investigated. The
studied location was a busy highway in Tehran. High performance liquid
chromatography equipped with florescence detector was used for
determination of polycyclic aromatic hydrocarbons concentrations in the
studied samples. Total concentration of the ten studied polycyclic
aromatic hydrocarbons compounds ranged from 11107 to 24342 ng/g dry
weight in the dust samples and increased from 164 to 2886 ng/g dry
weight in the soil samples taken from 300 m and middle of the highway,
respectively. Also the average of ∑ PAHs was 1759 ng/L in the
water samples of pools in parks near the highway. The obtained results
indicated that polycyclic aromatic hydrocarbons contamination levels
were very high in the vicinity of the highway. |
