Fishing Port Pollution due to the Vessel Activities along Bandar Abbas Coast, Iran

Bandar Abbas fish quays activities impacted on chemical compounds of the coasts. Three stations as Posht e Shahr (Ps), Sayadan (Sa) and Shilat (Sh) were selected to investigate the oil spill pollution and heavy metal concentrations in the regions. The sediment samples were collected in June and November 2017 then extracted. The highest concentrations were Fe>Zn> Pb>Cu>Cd respectively in the Sh quay. The cluster results indicated that Ni and Zn have the same sources but Pb, Cu and Cd were from different sources. Ni and Zn entered the environment due to the activities of ship repairs and coastal construction. Pb, Cu and Cd sources were from oil spills of fishing boats. The ERLQ and ERMQ toxicity rates of Ni at Ps and Sa were at the occasional but the Sh was at the frequent occurrence level. In November, the Cd toxicity at Sh was at occasional level. The new rules needed to control the pollution of quays operation.
