“… Comparison of the EC 50 values (mg/L) of Phaeodactylum tricornutum from other studies to the present study: ( a ) the EC 50 values of potassium dichromate at 72 h; ( b ) the Cu values at 72 h; ( c ) the Cd values at 72 h [ 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ]. …”

“…In the study of Uba [ 56 ], K 2 Cr 2 O 7 obtained an EC 50 value of 8.07 ± 0.03 mg/L, while the R 2 value was 0.99. Other authors have studied how species’ sensitiveness to the same chemicals can vastly vary [ 57 ]. They characterized the non-standardized diatom Chaetoceros tenuissimus by growth inhibition, biochemical, and infrared-spectroscopy (FT-IR) tests to compare the results to the standardized diatom Phaeodactylum tricornutum .…”

“…The two species were exposed for 72 h to four chemicals: nanoparticles (n-TiO 2 , n-ZnO), potassium dichromate, and surfactant (polyethylene glycol, PEG). The obtained EC 50 ± SD (mg/L) for P. tricornutum and C. tenuissimus were 22.97 ± 1.34 and 19.84 ± 1.45, respectively [ 57 ]. Other authors have evaluated the impacts of 16 different leachates of plastic-made packaging on marine species from different trophic levels (bacteria, algae, and echinoderms) [ 58 ].…”

“…EC 50 calculated for algae at 72 h was 8.11 mg/L. Pastorino et al [ 57 ] has demonstrated that EC 50 for P. tricornutum after 72 h of exposure to K 2 Cr 2 O 7 fell within the 16.76–20.84 mg/L interval. According to our results, EC 50 obtained for K 2 Cr 2 O 7 came quite close to the reference values of other papers, which indicates that this alga resisted Cr more than other HMs.…”

The escalating global anthropogenic activities associated with industrial development have led to the increased introduction of heavy metals (HMs) into marine environments through effluents. This study aimed to assess the toxicity of three HMs (Cr, Cu, and Cd) on organisms spanning different trophic levels: Phaeodactylum tricornutum (a primary producer), Artemia salina (a primary consumer), and Aurelia aurita (a secondary consumer). The EC50 values obtained revealed varying relative toxicities for the tested organisms. Phaeodactylum tricornutum exhibited the highest sensitivity to Cu, followed by Cd and Cr, while Artemia salina displayed the highest sensitivity to Cr, followed by Cu and Cd. A. aurita, on the other hand, demonstrated the highest sensitivity to Cu, followed by Cr and Cd. This experimental investigation further supported previous studies that have suggested A. aurita as a suitable model organism for ecotoxicity testing. Our experiments encompassed sublethal endpoints, such as pulsation frequency, acute effects, and mortality, highlighting different levels of sensitivity among the organisms.
