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.
