Comparing the sensitivity of two cogeneric ascidian species to two plastic additives: Bisphenol A and the flame retardant tris(chloro-propyl)phosphate

Although sensitivity to pollutants is well known be species specific, closely related are often assumed respond similarly them. We tested this assumption, comparing the of Ciona intestinalis and robusta two common marine pollutants: Bisphenol A (BPA) tris(1-chloro-2-propyl)phosphate (TCPP). In particular, we focused on ascidian embryonic development determined whether C. displayed different responses. Our results demonstrate that can display either similar or very based contaminant. had BPA, as their median effective concentration (EC50) lethal (LC50) values were comparable. contrast, TCPP showed teratogenic potential in analyzed species. proved more vulnerable flame retardant its index was than twice calculated for intestinalis.
