“…Indeed, the C free in a study of Hale et al (2012) ranged from 0.2-10 ng/L, with the highest concentration of 162 ng/L listed for a biochar produced via fast pyrolysis (gasification). These C free are lower than environmental background levels reported by Lang et al (2015). Thus, the bioavailability of biochar-bound PAHs is probably low in the short-term after soil application.…”

This article reviews the different aspects of biochar as source and sink of organic and inorganic contaminants. Biochar can contain organic contaminants such as polycyclic aromatic hydrocarbons or heavy metals. As the distribution coefficients of the biochar especially for contaminants are high, the freely dissolved concentrations are low and with that also the bioavailability. The link between biochar’s inherent contaminants and toxicity to soil meso– and macro–fauna remains unclear, with data being often contradictory and influenced by feedstock and pyrolysis conditions. The biochar’s potential to remediate contaminated soils has mainly been addressed in lab studies, but rarely in the field. This far, results have been contradicting. Many studies reported successful immobilization of contaminants but some not. In summary, the ambivalent face of the biochar with regard to contaminants prevails. In future, long term field studies are needed to properly address the sustainability of biochar in this respect.

“…Some key indicators for the impact of fisheries on ecosystems (see Link, 2005;Methratta and Link, 2006;Fay et al, 2013) such as the biomass of functional groups of fish species are not available for the 8-fjords, although some other indicators have been mentioned in the previous section. Indicators that describe other important aspects of ecosystem structure and function, such as water transparency, nutrient and toxin loads and concentrations (Håkanson and Blenckner, 2008;Fleming-Lehtinen et al, 2015;Lang et al, 2015), are available to some extent. Economic and social indicators are wanted while being of comparable importance as ecological ones (Leslie and McLeod, 2007;Fulton et al, 2014;Vinueza et al, 2014).…”

. (2017) AbstractThe coastal marine environment in the 8-fjords area on the Swedish west coast has been subjected to various stakeholder co-management initiatives since 1999. Stakeholders and authorities have acted by supporting and implementing gradually stricter fishing restrictions following the collapse in the 1970s of several demersal fish stocks and their apparent lack of recovery. Moreover, concerns have been raised regarding a locally sharp depletion of eelgrass meadows, in addition to an apparent increase in the number of seals and cormorants. The present 8-fjords

“…However, from a toxicological viewpoint these results are highly relevant. PHE, FLU, and PYR are by far the most commonly observed PAHs in surface waters and sediment of the Baltic Sea (Lang et al 2015;Witt 2002) and regularly forming the majority of the background PAH levels in the tissues of mussels as well (Turja et al 2012(Turja et al , 2014(Turja et al , 2015Lehtonen et al 2016). The marked decrease in the share of PHE, FLU, and PYR observed in the two highest oil treatments to the total of other PAH 18 compounds in the tissues of mussel during the experiment clearly indicates exposure to oil, and this observation could also be useful in field studies and monitoring of oil pollution.…”

In the brackish water Baltic Sea, oil pollution is an ever-present and significant environmental threat mainly due to the continuously increasing volume of oil transport in the area. In this study, effects of exposure to crude oil on two common Baltic Sea species, the mussel Mytilus trossulus and the amphipod Gammarus oceanicus, were investigated. The species were exposed for various time periods (M. trossulus 4, 7, and 14 days, G. oceanicus 4 and 11 days) to three oil concentrations (0.003, 0.04, and 0.30 mg L −1 based on water measurements, nominally aimed at 0.015, 0.120, and 0.750 mg L −1 ) obtained by mechanical dispersion (oil droplets). Biological effects of oil exposure were examined using a battery of biomarkers consisting of enzymes of the antioxidant defense system (ADS), lipid peroxidation, phase II detoxification (glutathione S-transferase), neurotoxicity (acetylcholinesterase inhibition), and geno-and cytotoxicity (micronuclei and other nuclear deformities). In mussels, the results on biomarker responses were examined in connection with data on the tissue accumulation of polycyclic aromatic hydrocarbons (PAH). In M. trossulus, during the first 4 days of exposure the accumulation of all PAHs in the two highest exposure concentrations was high and was thereafter reduced significantly. Significant increase in ADS responses was observed in M. trossulus at 4 and 7 days of exposure. At day 14, significantly elevated levels of geno-and cytotoxicity were detected in mussels. In G. oceanicus, the ADS responses followed a similar pattern to those recorded in M. trossulus at day 4; however, in G. oceanicus, the elevated ADS response was still maintained at day 11. Conclusively, the results obtained show marked biomarker responses in both study species under conceivable, environmentally realistic oil-in-seawater concentrations during an oil spill, and in mussels, they are related to the observed tissue accumulation of oil-derived compounds.
