This paper describes an equation of the lethality curve and a method for the determination of
its parameters. The equation is derived from the" one compartment" uptake and excretion …

Quantitative structure‐activity relationships (QSARs) predict bioconcentration and acute
toxicity to fish of chemicals causing narcosis on the basis of hydrophobicity, as measured by …

A method was developed to simultaneously ascertain 96 h LC 50 values for seven
freshwater species in a single flow through test with measured concentrations. It allows …

This chapter describes the parts of the Office of Pollution Prevention and Toxics (OPPT) new
chemical review process in which ecotoxicity data are used to provide evaluations of …

The survival of earliest man depended on recognition and avoidance of those plants and
animals which were poisonous by contact or ingestion. But early man also found that …

Acute toxicity tests were conducted with larvae of the midge Chironomus riparius (Meigen)
and nine relatively unreactive organic chemicals. A Quantitative Structure Activity …

In the past few years, there has been widespread acceptance of the idea that a scientifically
justifiable estimate of the hazard of a chemical to aquatic life can be obtained in a cost …

Derivation of quality standards to protect aquatic ecosystems demands a minimum set of
toxicity data to allow the risk assessor to take some account of:(1) variable responses to …

In recent years much work has been done to develop methods to assess the aquatic toxicity
of chemicals, effluents, and products. In seeking a more relevant ecological approach to …

Abstract Structure-activity models which were developed to estimate toxicity of chemicals to
freshwater fish were tested for use with an estuarine fish (Cyprinodon variegatus) and …
