“…The specific class of organochlorine pesticides (OCPs) has been largely studied in the literature due to their diffuse use in the last century and their impact on ecosystems and the environment (Di Muccio et al 1996;Lee et al 2001;Yang et al 2005;Marini et al 2012). Moreover, their levels of persistence and bioaccumulation represent an additional risk factor for the environment (Stefanelli et al 2004).…”

First groundwater chemical status assessment of the Buna River-Protected Landscape (Albania)

The Buna River-Protected Landscape is a Managed Nature Reserve and Ramsar site because of its high biodiversity; the water resources at this site represent a crucial element for the ecosystem conservation, especially for the avifauna and ichthyofauna. Water-quality assessment and monitoring are important to the water resource’s ecological value and the health of local populations to improve and promote sustainable agriculture and ecotourism. This paper reports a hydrogeochemical evaluation of sampled waters from the Buna River-Protected Landscape in northern Albania. There exist no previous studies that assess the environmental status of the local groundwater resources. Geochemical surveys of groundwater were conducted in October 2012, and February and June 2013 within the framework of the “International Union of Conservation of Nature”, granted by the Italian Ministry of Foreign Affairs. Twenty samples were analysed to (1) study several parameters with respect to 2000/60/EC and 2006/118/EC, which pose risk for environmental health and (2) evaluate the water quality and all processes that can influence it. The sampled groundwater was classified as calcium bicarbonate, and no evidence of saline intrusion phenomena was obtained, even in the area closest to the coast. Areas with a greater anthropogenic presence show NO3 levels above the European Union thresholds, probably due to the lack of wastewater management systems. A major concern is represented by the widespread presence of organochlorine pesticides, especially with reference to the Hexachlorocyclohexane isomers that have concentrations widely above the thresholds suggested by the European Union

“…The river crosses a wide industrial and agricultural area and largely contributes to the nutrient and chemical loads flushed into the sea (Calamari et al, 2003), with a mean rate of discharge of 1500 (Marini et al, 2010). As a result, in the last decades a variety of organic chemicals have been detected in this region, with significant concentrations both in species and environmental compartments (Marini et al, 2012, Bellucci et al, 2002, Horvat et al, 1999, Kannan et al, 2002.…”

Modelling bioaccumulation processes at the food web level is the main step to analyse the effects of pollutants at the global ecosystem level. A crucial question is understanding which species play a key role in the trophic transfer of contaminants to disclose the contribution of feeding linkages and the importance of trophic dependencies in bioaccumulation dynamics. In this work we present a computational framework to model the bioaccumulation of organic chemicals in aquatic food webs, and to discover key species in polluted ecosystems. As a result, we reconstruct the first PCBs bioaccumulation model of the Adriatic food web, estimated after an extensive review of published concentration data. We define a novel index aimed to identify the key species in contaminated networks, Sensitivity Centrality, and based on sensitivity analysis. The index is computed from a dynamic ODE model parametrised from the estimated PCBs bioaccumulation model and compared with a set of established trophic indices of centrality. Results evidence the occurrence of PCBs biomagnification in the Adriatic food web, and highlight the dependence of bioaccumulation on trophic dynamics and external factors like fishing activity. We demonstrate the effectiveness of the introduced Sensitivity Centrality in identifying the set of species with the highest impact on the total contaminant flows and on the efficiency of contaminant transport within the food web.

“…Moreover, the Southern Eastern Adriatic rivers are equally an important potential source of pollutants, being the mainly entrance to the Southern part of the Adriatic Sea (Marini et al, 2010). In relation to this aspects, several surveys conducted in different Adriatic regions report significant concentrations of different xenobiotics detected both in species and environmental compartment (Marini et al, 2012, Bellucci et al, 2002, Horvat et al, 1999, Kannan et al, 2002…”

Persistent Organic Pollutants represent a global ecological concern due to their ability to accumulate in organisms and to spread species-by-species via feeding connections. In this work we focus on the estimation and simulation of the bioaccumulation dynamics of persistent pollutants in the marine ecosystem, and we apply the approach for reconstructing a model of PCBs bioaccumulation in the Adriatic sea, estimated after an extensive review of trophic and PCBs concentration data on Adriatic species. Our estimations evidence the occurrence of PCBs biomagnification in the Adriatic food web, together with a strong dependence of bioaccumulation on trophic dynamics and external factors like fishing activity.
