Abstract
This work aimed to investigate the contamination pattern in Kongsfjorden marine environment (Svalbard, 79oN12oE) and to disentangle primary and secondary emissions. Surface seawater, sampled in two seasons, wasanalysed by GC-MS and LC-MS/MS to detect polychlorobiphenyls (PCBs), polycyclic aromatic hydrocarbons(PAHs), nonylphenols (NPs), bisphenol A (BPA) and perfluoroalkyl and polyfluoroalkyl substances (PFASs). Insummer, average ?PAHs, BPA, ?NPs, ?PFASs and ?PCBs concentrations were 17.3 ± 11.1 ng/L, 0.9 ± 0.3 ng/L,10.0 ± 6.9 ng/L, 0.4 ± 0.7 ng/L and 1.8 ± 1.3 pg/L, respectively; while in winter, they were 13.6 ± 10.1 ng/L,0.5 ± 0.2 ng/L, 6.8 ± 3.3 ng/L,I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
