Abstract The Pietra del Pertusillo freshwater reservoir is a major artificial lake of environmental, biological, and ecological importance located in the Basilicata region, southern Italy. The reservoir arch-gravity dam was completed in 1963 for producing hydroelectric energy and providing water for human use, and nearby there are potential sources of anthropogenic pollution such as urban and industrial activities. For the first time, the minero-chemistry of the lake and fluvio-lacustrine sediments of the reservoir have been evaluated to assess the environmental quality. Moreover, the composition of fluvial sediments derived from the peri-lacual zone of the reservoir and of local outcropping bedrock were also studied to understand the factors affecting the behavior of elements in the freshwater reservoir, with particular attention paid to heavy metals. In Italy, specific regulatory values concerning the element threshold concentration for lake and river sediments do not exist, and for this reason, soil threshold values are considered the standard for sediments of internal waters. The evaluation of the environmental quality of reservoir sediments has been performed using enrichment factors obtained with respect to the average composition of a reconstructed local upper continental crust. We suggest this method as an innovative standard in similar conditions worldwide. In the studied reservoir sediments, the trace elements that may be of some environmental concern are Cr, Cu, Zn, As, and Pb although, at this stage, the distribution of these elements appears to be mostly driven by geogenic processes. However, within the frame of the assessment and the preservation of the quality of aquatic environments, particular attention has to be paid to As (which shows median value of 10 ppm, reaching a maximum value of 26 ppm in Quaternary sediments), constantly enriched in the lacustrine samples and especially in the fine-grained fraction (median = 8.5 ppm).

The article is dedicated to the problem of artificial Lake Sasyk which was transformed from a salty water estuary into a freshwater reservoir at the expense of the Danube waters. In the first decades, the irrigative water conditions were not achieved due to the arrival of salts from the bottom sediments. Currently, the water quality formation process in Lake Sasyk has stabilized, but the problem of land irrigation remains urgent. The article gives an irrigation assessment of the quality of the Sasyk reservoir according to various methods considering observations in the HPS-2 region from 2007 to 2017. A detailed typification of irrigation waters based on Alekin O. A. water typing is proposed. It was found that mineralization and the content of sodium and magnesium ions in the Sasyk waters promote salinization and alkalinization of soils. For the safe use of this water for irrigation, both chemical reclamation and dilution with water are necessary.

The study looks at the problems facing coastal fishing communities. It highlights the impacts that, in the complex framework of the EU reforms, have manifested themselves on economic activities and on society. The aim of the paper is twofold: to examine small-scale artisanal fishing in an area of Southern Italy in order to develop resilience and diversification and at the same time to outline the profiles of local bluefish buyers to highlight development strategies for the sector. The research carried out through a direct survey by administering a questionnaire to fishermen operating in areas of Southern Italy and the data cross-referenced with the opinions of local consumers. A conjoint experiment, followed by a multiple correspondence analysis and cluster identification, was used to outline the profiles of local bluefish buyers. The results of the analysis reveal that the fish market and the restaurant sector are the main distribution channels preferred by fishermen. Furthermore, fishermen are very sensitive to environmental issues and are willing to collaborate and actively participate in the environmental protection of the sea. Consumers recognise the quality of local bluefish, and they implicitly perceive the sustainability of the method of capture. The results show the need to undertake synergistic actions for the fishing industry, capable of activating marketing strategies adequately to support, promote and develop the sector. The results of the study provide helpful information for food companies in order to better segment their market and target their consumers, as well as to effectively promote their product using brands, certifications and traceability.

To reuse municipal sewage sludge safely, experiment was carried out on grapefruit trees fertilized with composted sludge from Shiweitou Sewage Treatment Plant in Xiamen City of China, and a method was introduced of how to assess the environmental quality of grapefruit trees soil fertilized with sludge by Set Pair Analysis (SPA) model. The results showed that the soil in the surface layer (0-15cm) and the deeper layer (15-30cm) was less clean, and the environment of soil was not polluted. Thus it was feasible to use sludge as fruit fertilizer. The maximum service life of sludge for continuous land application was estimated by taking Cd as the limiting factor, which would provide scientific guide and technical support for safe land application of sludge.

Cointegration Relationship

The relationship between foreign direct investment, which is a type of cross-border and long-term investment, and environmental quality is a current issue that is heavily debated. Foreign direct invesments can ensure economic growth and development of countries, while also causing a change in environmental quality. In the research conducted, it is seen that changes in carbon dioxide emissions with foreign direct capital inflows are mainly investigated from the point of view of the host countries. However, foreign direct invesment outflows may have an impact on the environmental quality of the home country. Because foreign direct invesment outflows can enable the transfer of more environmentally friendly techonogies to the country and strengthen management skills. The impact of foreign direct investment outflows on the home country's environmental pollution is shaped by many factors (scale, technique, and composition effects). In addition to these effects, it is necessary to pay attention to the regional and sectoral distribution of capital outflows. The main aim of this study is to examine the links between Turkey's foreign direct invesment outflows and carbon dioxide emissions for the period 1990-2018. For this reason, a unit root test was applied to variables whose natural logarithm was taken. Tests showed that all series are stable of the same degree. Engle&Granger(1987) and Granger&Yoon(2002) tests were used to determine the cointegration relationship between variables. The crouching error correction model(CECM) was applied to determine the causality relationship. According to the results of the analysis; i) In terms of the Engle&Granger(1987) test, there was no long-term relationship between variables. ii) According to the Granger&Yoon(2002) test, it was determined that there is a bidirectional hidden cointegration relationship between the positive shocks of carbon dioxide emissions and negative shocks of foreign direct invesment outflows. iii) There is a bidirectional asymmetric causality relationship between the positive shocks of carbon dioxide emissions and the negative shocks of foreign direct invesment outflows. iv) It is observed that 1% negative shocks in foreign direct invesment outflows reduce positive shocks in carbon dioxide emissions by 0,26%. As a result, since negative situations in foreign direct invesment outflows have an effect on improving the quality of the environment, the environmental dimension should be taken into account in the policies to be made.
