Abstract :
Tracking and determining the amount and types of urban sewage that is being releasing to the environment is
important in planning for wastewater treatment systems and water quality control. In this research, in four stations of Anzali
Lagoon, (by means of a gas chromatograph device with mass detector spectrometer) wastewater pollution has been measured
and evaluated with molecular indicator Linear Alkyl Benzene(LABs) in bivalve “Anodonta cygnea”. Average concentrations of
LABs were calculated 520 μg/kg dry weight in samples of station 1, 1245 in station 2, 2144 in station 3, and 1746 in station 4.
Results from this study indicate severe LABs pollution in studied stations in Anzali Lagoon’s sugesing that urban wastewater
has reached these stations.
