| Popis: | In this study, heavy metal levels in sediments, human hair, and fish muscle tissue as well as organic matter (OM%) content in surface sediments of Chabahar Bay were determined to assess their ecological risks and sources. Totally, 96 samples were collected from 16 stations (Tiss, Konarak, desalination plant, entrance of Chabahar Bay, Posm, Ramin, and reference stations) and were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). Abundances of elements were of the following order: Ca>Al>Fe>Mg>Na>K>S>P>Ti>Mn>Sr>Ba>Cr>Ni>V>Li>Zn>Cu>Co>Pb>As>Cd>Ag>Se>Sb>Be>Mo>Bi. Element levels in sediments were within the range of low pollution areas, except for Cr, As, Ni, and Cd. Dominant sources of elements were natural, except for Cd, which was anthropogenic. All geo-accumulation index (Igeo) values were less than zero, except for Ag, Cd, and Sr from heavily to moderately contaminated areas. Eri values indicated low ecological risk, except for Cd which showed a high ecological risk. The As levels limit the consumption of fish meal per month. |
