Persistent organic pollutants in sediments from the Lagoon of Venice—a possible hazard for sediment-dwelling organisms

Quality assessment of escaping silver eel (Anguilla anguilla L.) to support management and conservation strategies in Mediterranean coastal lagoons

“…Over time, Mediterranean coastal lagoons have been affected by several anthropogenic impacts, resulting in an increase in eutrophication and pesticide loads into these shallow water ecosystems (Carvalho et al 2009;Parolini et al 2010;Ritson et al 2014;Pinto et al 2016). Severely degraded lagoons appear to be increasingly productive (Pérez-Ruzafa et al 2019), and this paradox may have supported eel production even in a situation of reduced recruitment (Aalto et al 2016;Leone et al 2016).…”

Polycyclic Aromatic Hydrocarbons (PAHs) in Surface Sediments of Two Polluted Lagoons in Saudi Arabia

“…Whereas the concentrations are far below the levels reported in Patos and Rodrigo de la Freita lagoons [43][44], Ebrie lagoon in Cote d'Ivoire [50], and Italy's Pialassa Baiona and Stagnone lagoons [41][42]. Moreover, the range of PAH concentrations found in the present study was around 100 orders magnitude higher than Italy's Lesina and Varano lagoons [51], and coastal lagoons in Mexico and Morocco [46,52]; 30 orders of magnitude higher than Italy's Santa Giusta and Orbatello lagoons [51], and Spain's Mar Menor lagoon [53]; and 25, 20, 18, 9, 7, 5, and 5 magnitudes higher than Skongalon and Skogar lagoons in Iceland [54], Venice [45], Bizerte [55], Italy's Marano and Grado lagoons [56], Berre in France [57], Yuandang in China [58], and Cotonou in Benin [59], respectively.…”

“…Table 4 presented the concentration levels of PAHs for some lagoons of different areas in the world. For individual congeners, pyrene and phenanthrene were the dominant compounds in both Al-Arbaeen and Al-Shabab similar to Pialassa Baiona and Stagnone lagoons in Italy [41][42], while the studied lagoons resemble Patos and Rodrigo de la Freita lagoons in Brazil [43][44], Venice [45], coastal lagoons in Mexico [46], and Ghar El Melh in Tunisia [47], where pyrene was the dominant compound. Comparing total PAH levels, the present concentration ranges were comparable with Etang de Thau, France [48], and Johnston Atoll in the USA [49].…”

“…The main sources of PAHs in Al-Arbeen and Al-Shabab were atmospheric deposition due to vehicle traffi c and municipal sewage. As shown in Table 4, industrial activities [41,43,45,50,55,57] along with municipal and urban runoff [51-52, 55, 57] contributed the dominant sources to PAH pollution in world lagoons. Moreover, agricultural runoff [46,51], aquaculture [42,46,52,60], petroleum spill, boat traffi c [44,52,59] and motor vehicles [44][45]58] also had considerable input.…”

Do males and females respond differently to ocean acidification? An experimental study with the sea urchin Paracentrotus lividus

“…About 200 adult specimens of P. lividus , with a live weight of 36.7 ± 11.4 g and a test diameter of 4.5 ± 0.5 cm, were collected by SCUBA divers at approximately 5 m depth in the southern basin of the Venice Lagoon (NW Adriatic Sea, Italy) between February and March 2017. The sampling area is close to the southern inlet of the lagoon where pollution levels are generally low (Parolini et al 2010 ; Parolini et al 2012 ; Cassin et al 2018 ; Zonta et al 2018 ). In the laboratory, animals were acclimated in flow-through aquaria for 2 weeks at least, at 18 ± 0.5 °C temperature and 34 ± 1 salinity, and fed with Ulva sp.…”
