“…Moreover, it is worth noting that the fate of pollutants is strongly influenced by the characteristics of the sea, such as water exchange capacity, as the enclosed or semi-enclosed basins (i.e., the Mediterranean Sea) are more susceptible to the accumulation of pollutants in marine sediments than open basins [9]. Among the organic micropollutants frequently detected in marine waters, are polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) [10,11]. PAHs represent pollutants of natural and anthropogenic origins (e.g., volcanic eruptions, combustion) while PCBs mainly derive from use in industrial activities (e.g., dielectric fluids, motor oils).…”

Polycyclic Aromatic Hydrocarbons and Polychlorinated Biphenyls in Seawater, Sediment and Biota of Neritic Ecosystems: Occurrence and Partition Study in Southern Ligurian Sea

et al. 2022

The Mediterranean Sea is subjected to a high anthropic pressure, which determines direct or indirect discharges of persistent organic pollutants deriving from intensive industrial activities. These compounds could easily enter and contaminate the whole marine compartment, with possible transfers (and contamination) among water, sediment and biota. Based on the above-mentioned assumptions, in this work we studied the presence of 16 polycyclic aromatic hydrocarbons (PAHs) and 14 dioxin and non-dioxin-like polychlorinated biphenyls (PCBs) in the neritic protected marine area of the Southern Ligurian Sea, affected by the impact of human activities. The study was focused on the possible partition of micropollutants within seawater, sediment and zooplankton. Results showed that both seasonal and anthropic causes strongly affect contaminant transfer behaviors, with summertime periods more impacted by PAH and PCB contamination. Regarding the PAH contamination, low molecular weight congeners were mainly detected in the target matrices, revealing concentrations up to 1 µg/L in seawater (anthracene), 250 µg/Kg in sediments (benzo[b]fluoranthene) and 2.3 mg/Kg in carnivorous copepods. Concerning PCBs, only few congeners were detected in the matrices studied. To better understand the occurrence of preferential bioaccumulation pathways in zooplankton, partition studies were also performed in several taxa (hyperbenthic Isopoda, holoplanktonic crustacean copepods and ichthyoplankton) through the calculation of BAF values, observing that both living and feeding habits could influence the bioaccumulation process.

“…Persistent organic pollutants are transported from primary and secondary sources (industry, agriculture, urbanized areas, transport, etc.) through the atmosphere, and they can be transported over long distances to areas of the World through natural atmospheric and oceanic processes where there are no anthropogenic activities, e.g., in Arctic soils (Gioia et al 2011;Cabrerizo et al 2018). Indeed, they are found all over the World, even in areas where these substances have never been used or produced (Puzyn and Mostrag-Szlichtyng 2012;Kallenborn et al 2015).…”

Over the past two decades, the presence of so-called emerging contaminants in various environmental compartments around the world, such as water, sediments, soils and atmosphere, and in a wide variety of consumer products has become a major concern for society, public health authorities, industry (namely food industry and water sector) and the agricultural sector. Some of these substances are endocrine disruptors and others are proven carcinogens and mutagens. In particular,

“…Their log Kow values ranged from 6.47 to 7.15 and increased as the molecular weights increases. POPs, being mostly hydrophobic have K ow ranging between 10 4 and 10 8 , and find their ways into the aquatic environment via atmospheric transport or from different tributaries, thus recording much higher level in freshwater column than in the marine water [67]. Just like PCBs, highly chlorinated congeners of PCNs are prone to deposit often in soils and sediments, given their higher K ow .…”

Polychlorinated naphthalenes (PCNs) are organochlorine compounds comprising the naphthalene ring system, in which one to eight hydrogen atoms have been substituted with chlorine atoms, yielding 75 chlorinated congeners. They were considered as persistent organic pollutants in May 2015 at the Stockholm Convention owing to their toxicity, persistence, bioaccumulation and potential for long-range transport in the environment. PCNs were invented in the early 1900s to be applied as flame-retardants in consumer products. Flameretardants are effective in minimizing fire-related problems. However, their negative environmental impacts have become of great concerns. Different analytical methods for the evaluation of PCNs in various environmental samples were reviewed in this article.. Their levels in human and some environmental samples across the globe are also mentioned. Reported data revealed that the highly toxic congeners (CNs 66, 67 and 73) are prevalent in most samples, there is need for their continuous monitoring in our environment.
