Toxic effects of hydroxylated aromatic hydrocarbons on marine embryos

Abstract
Phenol and methyl-substituted phenols were acutely toxic towards sea-urchin and fish eggs in concentrations of 3–30 ppm. Naphthols were considerably more toxic than phenols, killing most embryos even in concentrations of 0.3–3 ppm. Sublethal concentrations of phenols and naphthols caused pigment defects in cod larvae.
