“…For PBDEs, the assessment method was similar to that used for PFOA and PFOS (Table S6), and no significant risks were predicted in coastal and river sediments. For OCPs, a five-level classification for a Norwegian aquatic ecosystem, which was based on PNEC, was suggested as the coastal sediment quality criteria for Laizhou Bay and vicinity (Bakke et al, 2010). Under these criteria, Class I represents the background range; Classes II and III are the PNECs for chronic and acute exposure respectively; Class IV is 2-5 times the PNEC values, depending on the substances; and Class V includes the levels that are above class IV.…”

“…Almost all SUM PAH and individual PAH concentrations measured in surface sediments collected in this study correspond to background or low levels (level I or level II) after Bakke et al (2010), following the guidelines of the EU's Water Framework Directive (Electronic Yunker et al, 2002) in surface sediments. Yunker et al, 2002) in subsurface sediments.…”

“…The Norwegian Pollution Control Authorities have developed guidelines for environmental quality of contaminated sediments (Bakke et al, 2010) following the principles of the risk assessment guidelines of the European Water Framework Directive (WFD, 2000). The regulations define five classes based on the ecotoxicity of contaminants including PAHs (Bakke et al, 2010).…”

“…The regulations define five classes based on the ecotoxicity of contaminants including PAHs (Bakke et al, 2010). The five classes are; I: background levels of metal concentrations; II: low concentrations with no toxic effects; III: medium concentrations with toxic effects after chronic exposure; IV: high concentrations with toxic effects after short-time exposure; V: very high concentrations with acute toxic effects.…”

The concentration and distribution of polyaromatic hydrocarbons (PAHs) in surface and subsurface sediment samples from Tromsøflaket and Ingøydjupet, southwestern Barents Sea, were investigated in order to provide insight into the levels and origins of PAHs in a region with petroleum activities. PAH profiles in sediments were evaluated in context with sediment grain size and total organic carbon in order to assess the influence of ocean currents on the transportation and deposition of PAHs. The PAH concentrations are of background (Level I) to good level (Level II) based on the Water Framework Directive classification system. SUM PAH (SUM of 26 PAH compounds) ranged from 39 to 2197 µg/kg (average 225 µg/kg), and NPD (naphthalene, phenanthrene and dibenzothiophene, including their C1-C3 alkyl homologues) in surface samples ranged from 14 to 2045 µg/kg (average 157 µg/kg). However, the average values presented here are higher than have been reported in previous studies. The observed changes in PAH contents in surface and subsurface sediments vary in accordance with changes in grain size (clay and silt 17-99%) and total organic carbon content (0.37-0.98%). In turn, these sedimentary parameters are controlled by the inflow of Atlantic Water and the strength of the two predominating current systems in this region: the North Atlantic Current and Norwegian Coastal Current. Source-allocation modeling suggests that PAHs in surface samples are mainly of pyrogenic or mixed pyrogenic and petrogenic origin. Taken together, these patterns of PAH levels and sources reflect natural variability, indicating that the derived dataset establishes a pre-impacted baseline of the present state of the seafloor.

“…In our work, the values of the maximum concentration limit (MCL) were taken as a starting point for the estimation of sediment contamination. As MCLs used in Lithuania are different for bottom sediments of different composition (Lithuanian standards 2002), we applied the same classification as was used in the investigations of the Klaipėda strait (Galkus et al 2012b), where uniform MCLs are used for all bottom sediments (Bakke et al 2010). The Norwegian classification system is used to estimate the contamination of marine and lagoon sediments and focuses on toxicity to aquatic organisms as well as the impact to human health (Bakke et al 2010;Galkus et al 2012b).…”

Samples of surface (0–3 cm) bottom sediments of the Lithuanian aquatic area of the Curonian Lagoon and Nemunas River delta were taken from 41 sites in 2013 and 2014. Sediment parameters, such as the percentage of particles, concentration of organic carbon and heavy metals (Cu, Zn, Ni, Pb, Cr, Cd, and Hg), were determined. The heavy metal contamination of the surface layer of bottom sediments was determined using the Nemerov’s pollution index applied to soil. The spatial distribution of contamination indices and the dependence of contamination dynamics on sedimentation factors were analysed. It was determined that heavy metal concentrations had a tendency to increase as sediment particles became finer and as Corg concentration increased. A greater amount of pollutants got into the aquatic area of the Curonian Lagoon that was closer to the Klaipėda harbour than into other lagoon zones. The heavy metals for the integral pollution index for the Curonian Lagoon and Nemunas River delta surface bottom sediments could be arranged in the following order: Cd>Pb>Cu>Ni>Hg>Cr>Zn.
