20.500.12556/DiRROS-19448 Sediment contamination by heavy metals and PAH in the Piombino channel (Tyrrhenian sea) Sediment contamination is of major concern in areas affected by heavy maritime traffic. The spatial variation and contamination of 11 trace elements and 17 PAHs in surface sediments were studied along a 31 km transect along the seaway from the port of Piombino (Tuscany) to the port of Portoferraio (Elba Island) in the Northern Tyrrhenian Sea. Heavy metal contamination was detected at sites near Piombino (Ni, Pb, Hg, Cu and Zn) and at sites near Portoferraio (Pb, Zn, Hg, Cr and Cd). Each of the 35 sampled sites showed PAH contamination, with the highest concentrations at sites near Portoferraio. The most abundant isomers detected were 2- and 4-ring PAHs. PAH ratio analysis showed a prevalence of PAHs of pyrolytic origin. High values of PAHs and heavy metals were related to high sediment water content, TOC, silt, and clay content. Arsenic increased with increasing depth. The correlation between concentrations of metals and PAHs suggests common anthropogenic sources and is of concern for possible synergistic adverse effects on the biota. hidrobiologija težke kovine policiklični aromatski ogljikovodiki pomorski promet Tirensko morje true false true Angleški jezik Slovenski jezik Neznano 2024-07-18 03:50:08 2024-07-19 10:32:38 2024-07-20 04:02:58 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Soavtorji: Mistri Michele, Granata Tommaso, Moruzzi Letizia, Meloni Maria Laura, Massara Francesca, Sfriso Adriano, Sfriso Andrea Augusto, Munari Cristina; Opis vira z dne 27. 5. 2021; str. 1-18 iss. 11 Vol. 13 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-05-26 574 2073-4441 10.3390/w13111487 64902915 https://www.mdpi.com/2073-4441/13/11/1487 1 4f6a885c-4497-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26850 RAZ_Pitacco_Valentina_2021.pdf RAZ_Pitacco_Valentina_2021.pdf 1 A27400D7DF35AC63FB01D9C66533FF4E 7a1a2bf20f1ceda576fb054641799c8bce026b981e03c927f7f0d429832c336d be7a501a-4598-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26973 Nacionalni inštitut za biologijo 0 0 0
