Factors Determining Partitioning of Hydrophobic Organic Chemicals in Aquatic Organisms,ir relative importance. It is concluded that, although insufficient experimental data presently exist which can conclusively establish the cause(s), reduced lipid solubility and reduced bioavailability are the most likely factors contributing to the loss of linear correlation for non-metabolizing chemicals.

A Discussion of Correlations for Narcosis in Aquatic Species, in the target phase. If this hypothesis is accepted, it becomes possible to estimate and correlate target/octanol and target/water partition coefficients. Novel methods of presenting quantitative structure-activity relationships (QSARs) based on these partition coefficients are suggested. The hypot

The models allow for estimating appropriate descriptors of mobility, accumulation and persistence on the base of the substances’ physico-chemical propert

Of the three isomers, tissues of 1,2,4,5- tetrachlorobenzene treated rats had the highest radioactivity meas
