Description:
The purpose of this study was to evaluate Total petroleum hydrocarbons (TPHs) in surface sediments of Khamir,
Laft, and Yekshabeh and Tiab esturies. For this purpose, sampling of surface sediments was carried out at 16
stations (four stations at each estury.In each sample, four points were taken from the beginning, the middle, the
end and the junction point to the sea.The physicochemical properties of sediment such as grain size and total
organic matter (TOM) were measured using standard methods. The concentration of total petroleum
hydrocarbons was determined using Ultraviolet Fluorescence (UVF). Petroleum hydrocarbons showed limited
variations from 53.11 to 2052.5 ng/g dry weight in the summer season and from 128.5 to.4392.5 ng/g in winter.
The average detected concentrations for total hydrocarbons were lower than the environmental hazard (4000
ng/g). Most of their concentrations were observed at Yekshabeh estury in winter, possibly due to the pollution
caused by the activity of ports and fishing vessels. Also, the assessment of environmental hazard caused by
pollution of hydrocarbons for aquatic organisms by using SQSs and contamination coefficient (Cf) showed that
the studied sediments except station 1 at Yekhshabeh estury in winter season (Cf = 0.91) has no adverse
biological effects on aquatic organisms. Finally, the results of statistical analysis of the data showed that the
physicochemical parameters of sediments (grain size and total organic matter (TOM)) and the total petroleum
hydrocarbons were not correlated, which could indicate the existence of different sources for each studied
parameters.
