“…Trace elements concentration in the gonads is known to vary according to different biological (age, gender), physiological (reproduction) or environmental (season) factors (Warnau et al, 1998;Guendouzi et al, 2017;Rocha et al, 2019). The elementary constitution of the sea urchin reflects the composition of its environment and provides a basis for monitoring the patterns of change of contamination (Morrison et al, 2017).…”

An assessment of classical and emerging trace element contamination was conducted on gonads of the sea urchin Paracentrotus lividus (Lamarck, 1819), in Corsica (Western Mediterranean). The aim of this study was to evaluate the contamination levels at different sites by following the seasonal variation of 22 trace elements. The sea urchins analyzed were taken in 2017 from reference and more impacted sites in four Corsican areas. The results obtained shown the importance of biotic factors such as gender, reproduction and the way of life. Variations have been highlighted with lower trace element concentrations during the summer season. This is mainly due to a dilution phenomenon resulting from gametogenesis. The pollution index (TEPI) was determined and highlighted differences in contamination levels at the various sites. This work could provide additional support for other tools for the diagnosis and monitoring of coastal water quality. It provides useful new data to enable managers to act at the source and reduce degradation in order to improve the ecological quality of marine waters.

“…Being at the base of the food chain makes talitrid amphipods extremely well suited as bioindicators of anthropogenic contaminants in coastal regions. The assessment of their ability in bioaccumulation of various xenobiotics (e.g., heavy metals, PAHs) was the subject of recent investigations (e.g., Morrison et al 2017;Ugolini et al 2012aUgolini et al , 2012bUngherese et al 2010Ungherese et al , 2012Ungherese et al , 2016.…”

“…Among the sandhoppers, Talitrus saltator sensu lato (s. l.), which digs temporary refuges a few centimeters below the surface of the damp belt of sandy beaches, represents the majority of animal biomass in the supralittoral zone and an important food source for many invertebrates. Talitrus saltator has been the subject of studies on its genetic divergence (e.g., De Matthaeis et al 1998, 2000 and, more recently, it was also used as a bioindicator of environmental alterations including those due to heavy metal contamination (Ungherese et al 2010(Ungherese et al , 2012(Ungherese et al , 2016Ugolini et al 2012aUgolini et al , 2012bMorrison et al 2017).…”

Sandy beaches are ecosystems often subjected to a variety of pollution sources, including heavy metals and polycyclic aromatic hydrocarbons, largely due to improper human activities. The sandhopper Talitrus saltator s. l. (Montagu, 1808) typically lives on supralittoral shores where it plays an important ecological role. The purpose of this study was to investigate DNA damage levels on hemocytes of T. saltator by means of the Comet assay. Firstly, we tested the sensitivity and reproducibility of the Comet assay on hemocytes of T. saltator after in vitro exposure (1 h) to the genotoxicant methyl methanesulfonate (MMS). The data demonstrated a DNA damage (defined as % DNA tail) related to MMS exposure in a concentration-dependent manner. Next, we carried out the assay on hemocytes of T. saltator that were exposed in vivo (24 h and 7 days) to (a) lead (Pb), (b) benzo(a)pyrene (B(a)P), (c) mixtures of them. Our data on exposure to Pb or B(a)P showed DNA damage on the hemocytes of T. saltator in a concentration-dependent manner, but apparently with a nonsynergistic effect of exposure to their mixtures. Our results provide a background for further studies in order to verify the applicability of Comet assay on T. saltator for assessing genotoxicity levels in sandy beaches subjected to pollution.

A series of gold(I) complexes with the general formula [Au-(L2)(L')] (L2 = 4-phenyl-N-(prop-2-yn-1-yl)quinazoline-2-carboxamide, L' = PPh 3 (triphenylphosphine), 1; TPA (1,3,5-triaza-7phosphaadamantane), 2, and Me 2 -imy (1,3-dimethylimidazol-2ylidene), 3) were synthesized and fully characterized by spectroscopic methods. The alkynyl ligand L2 belongs to the quinazoline carboxamide class of ligands that are known to bind to the translocator protein (TSPO) at the outer mitochon-drial membrane. 1 and 2 exert cytotoxic effects in bladder cancer cells with IC 50 values in the low micromolar range. Further mechanistic analysis indicated that the two complexes both act by inducing reactive oxygen species and caspasemediated apoptosis. The complexes inhibit thioredoxin reductase, an established target of anticancer gold(I) complexes. Docking studies confirmed that after ligand exchange the free ligand L2 can interact with the TSPO binding site.
