| description | <p dir="ltr">The distribution, characteristics, sources and ecological risks of <u>polycyclic aromatic hydrocarbons</u> (PAHs) and hopanes in the surface sediments collected along the Qatar coast were investigated. Concentration of ∑<sub>14</sub>PAHs and hopanes ranged between 0.076 and 7.04 ng g<sup>−1</sup> (mean: 2.60 ng g<sup>−1</sup>), 100 and 700 ng g<sup>−1</sup> (mean: 205 ng g<sup>−1</sup>), respectively. Sediment samples were dominated by high molecular weight PAHs composition (4–6 rings). Diagnostic ratios of PAH concentrations showed both petrogenic and pyrogenic origins of PAHs, with a higher percentage of pyrogenic sources. The ecological risk levels of PAHs were estimated using sediment quality guidelines (SQG), mean probable effect level quotient values (PEL-Q), carcinogenic toxic equivalent quantity (TEQ), and risk quotient (RQ) evaluation methods. The calculated TEQ values (0.00012–0.85 ng g<sup>−1</sup>) were lesser than those in other locations around the globe, and were also within the safe level (600 ng g<sup>−1</sup>) suggested by the Canadian soil quality guidelines.</p><h2>Other Information</h2><p dir="ltr">Published in: Marine Pollution Bulletin<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.marpolbul.2024.116494" target="_blank">https://dx.doi.org/10.1016/j.marpolbul.2024.116494</a></p> |
