Determination of organic pollutants in sediment & some commercial species biota from eastern waters of Hormozgan province
This survey was conducted to determine the petroleum pollutants in sediment & some commercial aquatics of species in eastern waters of Hormozgan province during 2006-2008. We have selected 3 stations at 5, 10 and 20 meters depth in each of Sirik, Kuh-e-mobarak and Jask area. The selected biota were Penaeus indicus & Psettodes eruemi.Selected components of PAHs in sediment & biota samples were: Naphthalene (Na), Acenaphthylene (AcPY), Acenaphthene (AcP), Fluorene (FL), Phenantheren (PHEN), Anthracene (AN), Fluornthene (FLUR), Pyrene (PY), Benzo(a)anthracene (BaA) , Chrysene(CHRY), Benzo(b) fluoranthene (BaF), Benzo(k)fluoranthene (BkF), Benzo(a) pyrene (BaP), Dibenzo(a,h)anthrancene (dBAn), Benzo(ghi)perylene (BPe), Indeno (1,2.3-cd)pyrene (IcdP) . Our results were: Based to our results Bioaccumulation of PAHs didn't relate to sex and length of selected biota. Percent of naphthalene as a PAH with two rings has a significant difference against other PAHs in all areas. High ratio of HPAH to LPAH, show the combustion source of PAHs. Values for total PAHs at shrimp in Sirik, Kuh-e- mobarak & Jask area were 349.9 ±236.7, 809.1± 605.4 & 1015±1300.1 ng/g. Values for total PAHs at Psettodes eruemi, in Sirik, Kuh-e- mobarak & Jask area were 494 ±460.8, 1465.3±1678.2 and 292.3±400.7 ng/g respectively. In shrimp samples, the values for total PAHs had significant difference between Jask & Kuh e-mobarak, whereas for Psettodes eruemi, the significant difference was observed in Jask & Kuh-e-mobark. In sediment, concentration of total PAHs and their components didn't show any significant difference with area and depth of sampling at 95% confidence level. Average concentration of total PAHs and their components with 2, 3, 4, 5and 6 rings were 279.7±117.4, 4.5± 9.3, 6.2±7.1, 5.4±1.4, 263.6±113.9 respectively. Based to NOAA standards, pollution level of sediment is lower than ERL values.
