Biological impact of various chlorinated phenolics and related compounds on Daphnia magna: Biological impact of various chlorinated phenolics and related compounds on Daphnia magna. Durkin, Patrick R. (Coll. Environ. 494-99-5 which is the cas registry number is also used here. Sci. For., State Univ. New York, Syracuse, N. Y., USA). TAPPI Environ. Conf. [Proc.], 165-9 (English) 1978. CODEN: TECPDP. ISSN: 0364-2755. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) For a group of 17 methoxy-substituted arom. compds.In this experiment, several chemicals are used like 494-99-5 including 4-methylveratrole (I) [494-99-5], 4-methylguaiacol (II) [93-51-6], vanillic acid (III) [121-34-6], and some of their chloro derivs., both the acute lethal potency and bradycardic potency were related to the structure by the equation BR = k1p + k2p2 + k3F + k4R + k5MR + k6 (BR = biol. response, p = lipophilic parameter related to the octanol-H2O partition coeff., F = electronic field, R = electronic resonance, MR = molar refractivity) with correlation coeffs. >0.9. Structure-activity equations using fewer parameters suggested that the relation between bradycardia and lethality was incidental rather than intrinsic. These results are discussed in relation to the toxicity of kraft bleaching effluents. ..
