An extensive study was carried out in the Netherlands on the occurrence of a number of estrogenic compounds in surface water, sediment, biota, wastewater, rainwater and on the associated effects in fish. Compounds investigated included natural and sy

Bioconcentration is generally assumed to be similar to the partitioning of compounds between an aqueous and lipoid phase. In the case of bioconcentration lipoid phase is thought to consist of the lipid and lipoid tissues of an organism, e.g. a fish.

A series of acrylates and methacrylates was used to illustrate a strategy to compare the importance of two modes of action (MOA) and thereby identify the predominant cause of acute fish toxicity. Acrylic compounds are known to be Michael acceptors an

A model is presented for the acute toxicity of organophosphorus (OP) pesticides belonging to the class of phosphorothionates. The acute toxicity of these pesticides is governed by the irreversible inhibition of the enzyme acetylcholinesterase (AChE),

For aquatic toxicants that act by so-called nonpolar narcosis, it is generally acknowledged that the Critical Body Residue (CBR) at death, as a surrogate dose metric for the amount of target that has interacted with the toxicant, is constant. This co

Systematic toxicity testing, using conventional toxicology methodologies, of single chemicals and chemical mixtures is highly impractical because of the immense numbers of chemicals and chemical mixtures involved and the limited scientific resources.

In the current study, the suitability of negligible depletion solid-phase microextraction (nd-SPME) to determine free fractions of chemicals in aquatic environments was explored. The potential interferences of the dissolved matrix (i.e., humic acids)

QSARs were developed for the acute toxicity of narcotic pollutants (nonpolar and polar) to the water flea (Daphnia magna), the guppy (Poecilia reticulata), and the pond snail (Lymnaea stagnalis) using hydrophobicity (log KOW) and hydrogen bonding cap

In the current study we describe three approaches to derive quantitative structure property relationships (QSPRs) that give insight in the interactions that are important in membrane/water partitioning. In the first model only semiempirically (AM1) c

Narcosis I and II chemicals exhibit different lethal body burdens (LBBs) and acute toxicities (median lethal concentrations [LC50's]) in fish, when compared with their log n-octanol-water partition coefficient (K ow ). The higher toxicity of polar na
