“…Coastal environments are considered as places with a high ecological risk due to complex biogeochemical processes and intensive human activities (Li et al, 2014a;Schintu et al, 2015). Recently and due to rapid economic development and industrialization, the persistent organic pollutants such as aliphatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs), have highly concentrated in the coastal environments (Kapsimalis et al, 2014).…”

“…PAHs are produced by a wide range of processes including: the high temperature combustion of fossil fuels and biomass, volcanic eruptions, forest fires, oil spills, petrol and diesel leaks, domestic and industrial wastes and biological production Lourenço et al, 2013;Nguyen et al, 2014;Schintu et al, 2015). Like the PAHs, the origins of AHs may be marine oil and gas exploration, atmospheric deposition (dry and/or wet), municipal and industrial discharges, accidental spills, riverine input and waste incineration (Guigue et al, 2014a;Manuel Nicolaus et al, 2015;Schintu et al, 2015;Zhou et al, 2014).…”

Benthic foraminifera and ostracods, and resting stages (cysts) of plankton were analysed from surface sediment samples collected at 20 stations in the Mar Piccolo of Taranto (Ionian Sea, Mediterranean), with the aim to advance our knowledge on the biodiversity and ecological features of confined marine areas and to upgrade the autoecology of the species, and to have a more detailed and complete information to be applied as the baseline in future studies on environmental quality. In order to better assess the spatial distribution of the holobenthic and merobenthic species, we conceived a simple method of spatial analysis, based on all the identified taxa of foraminifera, ostracods and plankton cysts. Five groups were established on the basis of the number of sites per sub-basin where each taxon was registered, and this allowed us to recognise the preferential patterns of distribution for 150 species. The good correspondence between the results of the spatial analysis and those obtained from the analysis of the communities and the uni-and multivariate statistics showed a clear difference between the two sub-basins of the Mar Piccolo of Taranto.

The mining industry is a common source of environmental metal emissions, which cause long-lasting effects in aquatic ecosystems. Metal risk assessment is challenging due to variations in metal distribution, speciation, and bioavailability. Therefore, seasonal effects must be better understood, especially in boreal regions in which seasonal changes are large. We sampled 4 Finnish lakes and sediments affected by mining for metals and geochemical characteristics in autumn and late winter, to evaluate seasonal changes in metal behavior, the importance of seasonality in risk assessment, and the sensitivity and suitability of different risk assessment methods. We compared metal concentrations in sediment, overlying water, and porewater against environmental quality guidelines (EQGs). We also evaluated the toxicity of metal mixtures using simultaneously extracted metals and an acid volatile sulfides (SEM-AVS) approach together with water quality criteria (US Environmental Protection Agency equilibrium partitioning benchmarks). Finally, site-specific risks for 3 metals (Cu, Ni, Zn) were assessed using 2 biotic ligand models (BLMs). The metal concentrations in the impacted lakes were elevated. During winter stratification, the hypolimnetic O2 saturation levels were low (<6%) and the pH was acidic (3.5-6.5); however, abundant O2 (>89%) and neutral pH (6.1-7.5) were found after the autumnal water overturn. Guidelines were the most conservative benchmark for showing an increased risk of toxicity in the all of the lakes. The situation remained stable between seasons. On the other hand, SEM-AVS, equilibrium partition sediment benchmarks (ESBs), and BLMs provided a clearer distinction between lakes and revealed a seasonal variation in risk among some of the lakes, which evidenced a higher risk during late winter. If a sediment risk assessment is based on the situation in the autumn, the overall risk may be underestimated. It is advisable to carry out sampling and risk assessment during periods in which metals are assumed to be the most environmentally harmful.
