“…As soon as the organisms started releasing the gametes, they were targeted for the fertilization procedure. These experiments are internationally accepted as suitable for toxicity, hazard, or risk assessments [ 36 , 37 , 41 ], and have been employed to better understand negative effects on reproduction of an organism broadly recommended for water bioassays.…”

Graphical Abstract In view of the intense interest in applications of silver nanoparticles in products for the medical field and in food preservation packaging due to their antimicrobial properties, the ecotoxicology of silver nanocomposites was evaluated in films. Test with the sea urchin Echinometra lucunter , to evaluate embryonic development and contamination by the action of silver and titanium nanoparticles in polyethylene nanocomposite films presents new results. The silver nanoparticle’s stability in polymeric materials can be enhanced by adding carriers, such as titanium dioxide and montmorillonite clay (MMT) without to producing one unfriendly material. For this research, low-density polyethylene (LDPE)/linear low-density polyethylene (LLDPE) were used processed in a twin-screw extruder, followed by gamma irradiation with 25 kGy and characterized by ecotoxicology assays, field emission scanning electron microscopy (FESEM), scanning electron microscopy and energy dispersive spectroscopy (SEM–EDX), differential scanning calorimetry (DSC), thermogravimetric analysis (TG), Raman spectroscopy (SERS) and mechanical properties. The antibacterial properties of the LDPE films were investigated against Escherichia coli and Staphylococcus aureus . The gamma irradiation had an important effect in the synthesis of silver nanoparticles resulting in bactericidal activity and the death of 100% of the tested bacteria. The evaluation of the environment was considered with the ecotoxicological investigation carried out. The results indicated that the polymeric films with silver nanoparticles and TiO 2 do not contaminate the environment and neither interfere with the larval development of Echinometra lucunter . The obtained materials can be used in various applications with antimicrobial properties.

“…Another study [78] examined the effects of a combination of different doses of crack cocaine in some ocean acidification scenarios on sea urchin (Echinometra lucunter) reproduction. The authors found that fertilization rates decreased significantly after short-term exposure to cocaine, in conjunction with a decrease in water pH.…”

“…Studies performed on brown mussels ( Perna perna ) [ 77 ] reported an effect of crack cocaine on gametes and embryo-larval development, at high concentrations, in the order of mg/L, not yet reported in aquatic environments. Another study [ 78 ] examined the effects of a combination of different doses of crack cocaine in some ocean acidification scenarios on sea urchin ( Echinometra lucunter ) reproduction. The authors found that fertilization rates decreased significantly after short-term exposure to cocaine, in conjunction with a decrease in water pH.…”

Cocaine is one of the most widely used drugs that, due to its molecular properties, causes various behavioral alterations, including sexual behavior. In vivo and in vitro studies conducted mainly in mammals have shown various disorders of sexual activity and morpho-functional dysfunctions of the gonads in both sexes. Although the modalities are still unclear, cocaine has been shown to alter the cell cycle, induce apoptosis, and alter sperm motility. In females, this drug alters the formation of the meiotic spindle as well as may obstruct the ovulation mechanism of mature oocytes. The data provided in this review, in addition to reviewing the current literature on the main effects of cocaine on spermatogenesis and oogenesis mainly in mammals, will hopefully provide a basic overview that may help and support further future studies on the molecular interaction of cocaine and its metabolites with germ cells.

“…Experimental treatments (FSW or MP solutions) were acidified by adding 10% HCl (PanReac, Castellar del Vallés, Barcelona) in a dropwise manner under continuous stirring until pH stabilization (Bellas et al, 2003;da Silva Souza et al, 2019;Kurihara and Shirayama, 2004;Saco-Álvarez et al, 2010;Yamada and Ikeda, 1999). The pH was checked before starting the incubation and right after ending exposure.…”
