“…All TBT concentrations in the sediment of Svalbard harbours were below the lowest action level of 3 ng Sn/g (Stronkhorst and Van Hattum 2003). A field study in Greenland harbours showed that imposex in gastropods may be a more sensitive biomarker for the presence of TBT in the marine environment than the analysis of TBT in sediment or biota samples (Strand et al 2006).…”

Arctic sea routes are opening up for maritime transport due to sea ice retreat leading to increasing human activities in the Arctic and concomitant pressures on the environment. Organotin compounds are used in antifouling paints of large seagoing vessels and are known to leach into the marine environment and accumulate in sediments and biota. As organotin levels in Svalbard sediments have not been documented in peer-reviewed literature before, this study describes the levels in sediment of harbours around Svalbard (Ny-Å lesund, Longyearbyen, Svea, Pyramiden and Barentsburg). Organotin levels in sediments of Svalbard harbours were low (below the detection limit up to 14 ng Sn/g dw sum-butyltin) compared to other Arctic regions with a longer history of shipping. Levels were below known no effect levels and in accordance, no imposex was found in marine whelks from Ny-Å lesund harbour. Of all other analysed compounds in sediments of Kongsfjorden (polycyclic aromatic hydrocarbon (PAHs), polychlorinated biphenyls, polybrominated diphenylethers and perfluorinated compounds) PAH levels were highest and in one sample above action levels. It is advised to continue monitoring contaminant levels, for which the current results form a good basis. If contaminant levels rise, mitigation measures can be taken in time.

“…Coastal harbours are also prone to siltation as a result of the influxes of sediment-laden seawater (Senten, 1989; with subsequent deposition and accumulation of the sediments within the harbour basin under favourable hydrodynamic conditions . Chemical pollution and high sediment accumulation rates (SARs) in harbours are major environmental issues as they pose a threat to harbour sustainability and result in adverse human health, ecological and socio-economic impacts Van Rijn 2005;Casado-Martinez et al, 2006;.…”

“…Dredging has both economic and ecological implications as it is usually costly and moreover, the pollutants in the disposed materials are capable of exerting detrimental effects on the receiving ecosystems Casado-Martinez et al, 2006;Choueri et al 2009;. Thus, dredged material disposal is now recognized as a major environmental issue.…”

“…Sediment pollutants of notable concern include metals and persistent organic pollutants (POPs), exemplified by polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs), due to their toxicity, environmental persistence and potential for bioaccumulation and transfer along food chains (Chau, 2005;Casado-Martinez et al, 2006;Romano et al, 2013). Thus, information on sediment contamination and accumulation rates in harbours is relevant for their management, e.g., for predicting the time to dredge.…”

However, harbour sediments are often contaminated by a wide range of chemical pollutants (Casado-Martinez et al, 2006;. The aim of this …”

Currently, risk assessment for oil contamination does not consider behavioral responses of benthos to oil toxicity. Avoidance of oil-contaminated sediment by benthic amphipods, however, may be a highly sensitive endpoint for sublethal effects of commonly used distillate fuels. In the present study, the avoidance behavior of temperate freshwater (Gammarus pulex) and marine (Gammarus locusta) amphipods was tested by allowing them to choose between a reference sediment and a distillate marine grade A (DMA) oil-spiked sediment. Avoidance of DMA-spiked sediment at 1000 mg/kg dry weight was significant within the total exposure time (96 h) in G. pulex and within the first 72 h in G. locusta in 1 of 2 tests. Absence of DMA avoidance at lower concentrations (≤250 mg/kg dry wt) indicates that test species can only detect DMA above these concentrations. However, sensitivity to oil may vary according to the phenology and physiological conditions of the populations involved, such as the species temperature tolerance and reproductive stage. The results suggest that avoidance tests may be used as an alternative to traditional chronic toxicity tests provided that a causal link between avoidance and long-term effects can be established.
