measurement of pcb compounds in the persian gulf (southern pars area)

objective: the objective of this research is to examine pcb compounds in the persian gulf in the southern pars area. methods: in the research, 6 stations were sampled: asalouyeh port, kangan site, mehr petro kima petrochemical, 4th refinery in southern pasr, taheri port and aria sasol polymer. to sample water in the stations determined, one-liter sampling bottles of dark glass were used. in each station, samples were taken on three points. after recording sampling time and place, samples, with no adding any material, were transferred to the laboratory for measurements. pcb compound measurements were made by a gc-mas apparatus. limit of detection (lod) was 71 pg/lit. one-way analysis of variance was used to compare pcb concentrations in water, as well as compare contamination rate in different stations. all above steps were performed by the spss software. results: the results showed that average pcb compounds in asalouyeh port, kangan site, mehr petro kimia petrochemical, 4th refinery in southern pars, taheri port and aria sasol polymer were 99.3, 105.5, 110, 117, 123 and 130 ng/l, respectively. comparison of the six study stations indicated that the station of aria sasol polymer was the most polluted and had the highest contamination.
