Molluscan shellfish aquaculture is considered a “green” industry because of the limited presence of chemicals and risk of pathogens during farming in licensed areas, which provide a safe, nutritive and healthy food source. Moreover, the environmental impact of their production is lower than all other fish animal per unit of protein. In particular, mussels’ production was the first organized mollusk aquaculture in Europe and is now one of the most extended. Italy is the second main European producer of mussels. Taking into account the relevance of the sector, Italian Mediterranean mussel (Mytilus galloprovincialis) aquaculture has been considered for a life cycle assessment (LCA), from a cradle-to-gate perspective. The mussel farms were located in the northern Adriatic Sea, close to the Po River Delta, a region traditionally vocated to bivalve aquaculture. Results have shown that the growing and harvesting phases are the most critical life cycle stages (“hotspots”) due to the production and use of boats, and the great quantity of non-recyclable high-density polyethylene (HDPE) socks used during the yearly productive cycle. Several improvement potentials have been identified and estimated by means of a sensitivity analysis. Furthermore, regarding the principal exporting countries to Italy (Spain and Chile), the transport factors in an overall sustainability assessment have been considered, in order to compare the local and global mussels supply chain.

Abstract The Sacca di Goro is a shallow, brackish, eutrophic coastal lagoon in the southernmost part of the Po River Delta (northern Adriatic Sea, Italy). It is heavily exploited for rearing the Manila clam (Tapes philippinarum), mean annual production since 1986 being 10 000 t. Commercial cultivation of bivalves can exert severe impact on a local environment, especially on the invertebrate community, reducing species richness and abundance. An in situ experiment was conducted from March 2003 to February 2004 to examine the effect of clam cultivation on the macrobenthic community. Replicated sites within an area licensed for clam farming were seeded with low (500 m−2) and high (1500 m−2) clam densities; the surrounding unseeded areas were used as a control. There were only weak effects of clam presence and density on macrobenthic community abundance and functional group composition. The main determinants regulating the macrobenthic community were seasonal variations in other biota, particularly proliferation of the invasive mussel, Musculista senhousia, in August, which in turn caused a significant increase in the biomass of surface deposit-feeders and the subsequent development of Ulva rigida beds in September.

A detailed review of harmful algal blooms (HAB) in northern Adriatic Sea lagoons (Po River Delta and Venice lagoon) is presented to provide “updated reference conditions” for future research and monitoring activities. In the study areas, the high mollusc production requires the necessity to identify better methods able to prevent risks for human health and socioeconomical interests. So, an integrated approach for the identification and quantification of algal toxins is presented by combining microscopy techniques with Liquid Chromatography coupled with High Resolution Time of Flight Mass Spectrometry (HPLC-HR-TOF-MS). The method efficiency was first tested on some samples from the mentioned coastal areas, whereDinophysisspp. occurred during summer in the sites directly affected by seawaters. Although cell abundance was always <200 cells/L, the presence of Pectenotoxin-2 (PTX2), detected by HPLC-HR-TOF-MS, indicated the potential release of detectable amounts of toxins even at low cell abundance.

The Impact

To assess the potential environmental impact of human/industrial systems, life cycle assessment (LCA) is a very common method. There are two prominent types of LCA, namely attributional (ALCA) and consequential (CLCA). A lot of literature covers these approaches, but a general consensus on what they represent and an overview of all their differences seems lacking, nor has every prominent feature been fully explored. The two main objectives of this article are: (1) to argue for and select definitions for each concept and (2) specify all conceptual characteristics (including translation into modelling restrictions), re-evaluating and going beyond findings in the state of the art. For the first objective, mainly because the validity of interpretation of a term is also a matter of consensus, we argue the selection of definitions present in the 2011 UNEP-SETAC report. ALCA attributes a share of the potential environmental impact of the world to a product life cycle, while CLCA assesses the environmental consequences of a decision (e.g., increase of product demand). Regarding the second objective, the product system in ALCA constitutes all processes that are linked by physical, energy flows or services. Because of the requirement of additivity for ALCA, a double-counting check needs to be executed, modelling is restricted (e.g., guaranteed through linearity) and partitioning of multifunctional processes is systematically needed (for evaluation per single product). The latter matters also hold in a similar manner for the impact assessment, which is commonly overlooked. CLCA, is completely consequential and there is no limitation regarding what a modelling framework should entail, with the coverage of co-products through substitution being just one approach and not the only one (e.g., additional consumption is possible). Both ALCA and CLCA can be considered over any time span (past, present & future) and either using a reference environment or different scenarios. Furthermore, both ALCA and CLCA could be specific for average or marginal (small) products or decisions, and further datasets. These findings also hold for life cycle sustainability assessment.

Social Life Cycle Assessment

When considering the sustainability of production processes, research studies usually emphasise environmental impacts and do not adequately address economic and social impacts. Toy production is no exception when it comes to assessing sustainability. Previous research on toys has focused solely on assessing environmental aspects and neglected social and economic aspects. This paper presents a sustainability assessment of a toy using environmental life cycle assessment, life cycle costing, and social life cycle assessment. We conducted an inventory analysis and sustainability impact assessment of the toy to identify the hotspots of the system. The main environmental impacts are eutrophication, followed by terrestrial eco-toxicity, acidification, and global warming. The life cycle costing approach examined the economic aspect of the proposed design options for toys, while the social assessment of the alternative designs revealed social impacts along the product life cycle. In addition, different options based on the principles of the circular economy were analysed and proposed in terms of substitution of materials and shortening of transport distances for the toy studied.

Climate change will require societal-scale infrastructural changes. Balancing priorities for water, energy, and climate will demand that approaches to water and energy management deviate from historical practice. Infrastructure designed to mitigate environmental harm, particularly related to climate change, is likely to become increasingly prevalent. Understanding the implications of such infrastructure for environmental quality is thus of interest. Environmental life cycle assessment (LCA) is a common sustainability assessment tool that aims to quantify the total, multicriteria environmental impact caused by a functional unit. Notably, however, LCA quantifies impacts in the form of environmental “costs” of delivering the functional unit. In the case of mitigation infrastructures, LCA results can be confusing because they are generally reported as the harmful impacts of performing mitigation rather than as net impacts that incorporate benefits of successful mitigation. This paper argues for defining mitigation LCA as a subtype of LCA to facilitate better understanding of results and consistency across studies. Our recommendations are informed by existing LCA literature on mitigation infrastructure, focused particularly on stormwater and carbon management. We specifically recommend that analysts: (1) use a performance-based functional unit; (2) be attentive to burden shifting; and (3) assess and define uncertainty, especially related to mitigation performance.

Long-term data series (1971–2015) of physical and biogeochemical parameters were analyzed in order to assess trends and variability of oceanographic conditions in the northern Adriatic Sea (NAS), a mid-latitude shallow continental shelf strongly impacted by river discharges, human activities and climate changes. Interpolation maps and statistical models were applied to investigate seasonal and spatial variability, as well as decadal trends of temperature, salinity, chlorophyll-a and nutrients. This analysis shows that sea surface temperature increased by +0.36% year−1 over four decades. Annual mean flow of the Po River markedly changed due to the occurrence of periods of persistent drought, whereas the frequency of flow rates higher than 3000 m3 s−1 decreased between 2006 and 2015. Moreover, we observed a long-term decrease in surface phosphate concentrations in Po River water (−1.34% year−1) and in seawater (in summer −2.56% year−1) coupled, however, to a significant increase in nitrate concentration in seawater (+3.80% year−1) in almost all seasons. These changes indicate that the nutrient concentrations in the NAS have been largely modulated, in the last forty years, by the evolution of environmental management practices and of the runoff. This implies that further alteration of the marine environment must be expected as a consequence of the climate changes.

ABSTRACT The concentrations of the trace elements zinc (Zn), arsenic (As), manganese (Mn), copper (Cu), chromium (Cr), nickel (Ni), cobalt (Co), cadmium (Cd), lead (Pb), mercury (Hg), and iron (Fe) were examined in Mediterranean blue mussels (Mytilus galloprovincialis) from the Northern Adriatic Sea to determine whether there were site differences and seasonal variations in metal concentrations and to evaluate the potential health risks of consumption of these mussels to humans. Mussels were collected between January and October 2015 from three Slovenian shellfish harvesting areas and from a lighthouse near Debeli Rtič. The concentrations of elements were determined using inductively coupled plasma mass spectrometry. The amount of each element decreased in the following order: Fe &gt; Zn &gt; (As, Mn) &gt; (Cu, Cr) &gt; (Ni, Co) &gt; (Cd, Pb) &gt; Hg. Statistical analysis revealed that time, that is, the month of sampling, significantly affected the concentrations of elements in mussels (P &lt; 0.05). The concentrations of Cr, Mn, Fe, Ni, Hg, and Pb were highest between January and March and lowest between May and September. The concentrations of other elements in mussels were not higher or lower for several consecutive months, but occasionally (some months) lower or higher content was detected. The sampling site had a statistically significant effect only on the content of Cd, Pb, and Hg in mussels (P &lt; 0.05). The lowest level of these elements was found in mussels from Seča, and the highest levels of Hg and Pb were found in mussels from Debeli Rtič. Debeli Rtič is, among all sampling points, closest to the outflow of the Soča River that brings heavy metals into the Northern Adriatic Sea from a closed Hg mine. Because the concentrations of Pb, Cd, and Hg in all analyzed samples were below the maximum level permitted by Commission Regulation No 1881/2006, mussels were suitable for human consumption.
