Mimosa tannin and phenol-based synthetic tannin (syntan) were tested for toxicity to sea urchin ( Paracentrotus lividus and Sphaerechinus granularis) early development and to marine algal growth ( Dunaliella tertiolecta). Sea urchin embryogenesis was affected by vegetable tannin and syntan water extracts (VTWE and STWE) at levels ≥1 mg/L. Developmental defects were significantly decreased at VTWE and STWE levels of 0.1 and 0.3 mg/L when control cultures displayed suboptimal quality, i.e.
