Abstract |
|
Surface sediments were collected from 32 sites in
the Ambarlı Port located in the northern coast. of
the Marmara Sea and analysed for 16 polycyclic
aromatic hydrocarbons (PAHs) listed as the priority.
pollutants by the US EPA. Total concentrations of
the PAHs ranged from 56 to 3685 ng/g, dry weight,
and the highest values were recorded
at the coast locations, and the
anchoring areas.
Source analysis using the isomer ratios suggested
that the PAHs in the Ambarlı Port area sediments
were derived to a mixture of the pyrolytic input
coming from anthropogenic combustion processes such
as industry, vehicles and heating processes.
Further, the carcinogenic PAH levels at the near
shore and anchoring areas around the Ambarlı Port
were exceeded the effect range low (ERL), and could
cause the acute biological impairments when compared
to the sediment quality quidelines.
