These compounds can still be widely found in the environment due to it recalcitrance, lipophilicity, and bioaccumulation. This study aimed to investigate the ecotoxicological and cytotoxic effects of BPZ and BADGE on <i>P. tricornutum</i> and <i>M. galloprovincialis</i> to compare the produced effects with the sum of the effects caused by each substance.&nbsp; We also intend to establish a positive correlation between the results obtained from the <i>P. tricornutum</i> and <i>Mytilus</i> assays for each tested compound, also sharing information regarding the cell replicates exposed to the toxicants. The experimental data will allow the estimation of harm caused by these toxicants in the <i>M. galloprovincialis</i> earlier life stage, contributing to an environmentally safe future application of these compounds. Comprehending these intricate effects is crucial for a comprehensive ecological risk assessment and necessitates further investigation into the mechanisms behind the detrimental effects of BPZ and BADGE on marine ecosystems.</span></span></span> Bisphenol Z, Bisphenol A diglycidyl ether, Mytilus galloprovincialis, Phaeodactylum tricornutum, Ecotoxicology, Physiological effects, Algal growth inhibitions 23 40 http://jifro.ir/browse.php?a_code=A-10-5161-1&slc_lang=en&sid=1 B.
