Prediction of Rat Oral LD50 From , LC50 and Chemical Structure,pecies represent widely different animals, it is possible to achieve reasonably good predictions of the mammalian endpoint. A regression equation based on 147 diverse chemicals for which both endpoints were available has a correlation coefficient square of 0.75. The independent parameters consisted

Factors Determining Partitioning of Hydrophobic Organic Chemicals in Aquatic Organisms,linearity for very hydrophobic compounds. In order to establish the possible cause(s) of this phenomenon, the roles of metabolism, exposure time, membrane permeation, lipid solubility, and bioavailability on the biocon- centration potential of chemicals, are discussed. Data are presented showing the

Quantitative Structure-Activity Relationship Studies: Acute Toxicity of Environmental Contaminants,ted organic compounds which constitute a major group of potential environmental contaminants. Accessible surface area (ASA) and surface area (SA) are employed as the structure quantifiers for the LFER model, whereas Fujita-Ban approximations are used for the . calculations. The chemicals studied inc

Relationship between Toxicity and Bioconcentration for Some Organic Chemicals. I. Examination of thould be relatively constant for the biological response in question. It can be shown, employing existing acute and chronic toxicity QSARs and bioconcentration log K. relationships, that this is true. Equipotency does appear to exist, at least as a first approximation, and estimated whole body toxica

Relationship Between Toxicity and Bioconcentration for Some Organic Chemicals. II. Application of ter, one-compartment model assumptions, to estimate toxicant kinetic parameters. This was accomplished via non-linear curve fitting to time-toxicity data from typical LC50 toxicity tests. Preliminary results for a limited data set are presented. It appears that:
