“…Furthermore, the Tyrrhenian coasts are among the most polluted ones of Mediterranean area, like eastern Campania (“Land of Fire”) and many others in the entire area (Tamburrino et al, 2019 ; Triassi et al, 2019 ; Vichi et al, 2019 ). Decades of waste dumping practices, associated with the widespread use of pesticides and fertilizers, incineration processes, and massive release of environmental contaminants, have contaminated the whole environment, including the marine coastal ecosystem (Ariano et al, 2019 ; Esposito et al, 2018 ; Legambiente, 2003 , 2007 , 2018 ; Piazzese et al, 2019 ; Rodhouse et al, 2015 ; Senior & Mazza, 2004 ).…”

The present paper aims to investigate the ecological role of Merluccius merluccius, Linnaeus, 1758, in southern and central Tyrrhenian Sea (GSA 10, Resolution GFCM/33/2009/2 General Fisheries Commission for the Mediterranean), analyzing ontogenetic diet shifts, geographical variations on prey composition, and feeding habits. A total of 734 hake specimens ranging in size between 6 cm and 73 cm (Total Length, TL) were collected in 2018. In order to evaluate ontogenetic shifts in prey composition, samples were divided into five size classes and for each class the quantitative feeding indices have been calculated. The statistical analysis, based on index of relative importance percentage (%IRI), resulted in three trophic groups. The most abundant prey found in the immature hake specimens (size class I) were the Euphausiids, Stylocheiron longicorne and Mysidacea, while for samples with a total length over 10.5 cm were crustaceans and fish. Engraulis encrasicolus was the most abundant fish prey identified, followed by Boops boops and Myctophids. The high presence of Euphausiids, Mysids, Myctophidae, and Sternoptychidae in classes I, II, II, and IV (6–23 cm) showed the relevant role of mesopelagic fauna in hake diets, with an essential organic matter and energy flow from the mesopelagic to the epipelagic environment. Additionally, decapod crustaceans were found in the stomach contents of hakes belonging to class V (with size over 36 cm TL), which is notable considering that our study area includes an important decapod crustacean fishing area.

“…Photochemical formation of ozone has been reported with mostly slow increase in the Western Mediterranean area in background stations, following the low precursor emissions of NO X and VOC, while the increase in ozone volume ratios was much higher at urban stations [38]. On account of the influence of VOC on ozone formation in the maritime boundary layer over the sea, research is conducted directly on the sea with no significant impact on the ozone concentration found [39,40]. Ship emissions across the Mediterranean Sea show positive contribution to the summertime average ozone volume ratios of up to 12 ppb and up to 40 ppb near busy lines, such as should be the situation in Malta [41].…”

Long-term data analysis of the hourly ozone volume fractions in the middle of the Mediterranean Seawas carried out covering a period of 22 years. It was noticed that the amount of ozone during this period very rarely exceeded the recommended upper limit value of 80 ppb and that the amount of tropospheric ozone in the area is rather low. Fourier data analysis shows the presence of only a seasonal cycle in ozone concentrations. Statistical analysis of the data is showing a slightly negative trend in ozone concentrations of −0.46 ± 0.08 ppb/year for average values and a slightly higher negative trend of −0.54 ± 0.11 ppb/year for the 95th percentile values. These results obtained through simple linear regression were confirmed using the more appropriate Mann–Kendall test. The possible quadratic trend was not observed for the whole series of data. Air mass trajectories were calculated for those days in the year with the highest pollution, indicating that during those days horizontal air transfer, in most cases, brings the air mass from the North and from Sicily in Southern Italy.

“…Research activity in the Mediterranean basin was also carried out by the Institute of Atmospheric Pollution Research of the National Research Council (CNR-IIA) in the framework of the Med-Oceanor measurement program through cruise campaigns performed regularly since 2000. In 2015 the cruise of the research ship "Minerva Uno" followed a route in the central Mediterranean area (Tyrrhenian Sea) which also included the Aeolian Islands [8,9] and in 2017 the evaluation of the impact of this geologically active field on air quality of the southeastern area of Tyrrhenian Sea represented one of the research objectives of the cruise [10].…”

The results of air pollution assessment during a 2017 cruise of the research ship “Minerva Uno” in the Tyrrhenian Sea are reported. Volatile Organic Compounds (VOCs), Oxygenated Volatile Organic Compounds (OVOCs), and pollutants such as nitrogen oxides, ozone, and sulphur dioxide were monitored throughout the cruise. The shallow waters at ten sites of the investigated area were also analyzed. Organic compounds such as n-alkanes showed a bimodal distribution with a maximum at C5–C6 and C10–C11 at sites the most affected by anthropic impact, whereas remote sites showed a unimodal distribution with maximum at C10–C11. The most abundant atmospheric OVOC was acetone (3.66 μg/m3), accounting for 38%; formaldehyde (1.23 μg/m3) and acetaldehyde (0.99 μg/m3) made up about 22–29% of the total. The influence of some natural sources as volcanoes, in the southern part of the Tyrrhenian Sea near the Aeolian arc was studied. This source did not induce any noticeable effect on the total amount of hydrocarbons nor on the levels of trace gases such as CFCs, whereas the trends of sulphur dioxide seemed to confirm a possible contribution. The impact of underwater emissions was observed near the Panarea and Vulcano islands, where lower pHs, high levels of Fe and Mn, and diagnostic of vent activity, were measured.
