A spatially and temporally explicit risk assessment for salmon from a prey base exposed to agricultural insecticides
This risk assessment applied a framework for determining probable co‐occurrence of juvenile spring Chinook salmon (Oncorhynchus tshawytscha) with agricultural pesticides in the Willamette Basin, Oregon (Teply et al. this issue) to characterize risk to the threatened population. The assessment accounted for spatial and temporal distribution of 6 acetylcholinesterase‐inhibiting insecticides in ...

Toxicity of the effluents of Three Pharmaceutical Companies as Assessed with a Battery of Tests
Abstract: The toxicity of 27 samples of effluents of three pharmaceutical plants located in Belgium, has been determined with the aid of a battery of tests. Besides conventional bioassays representative for three different trophic levels (microalgae withSelenastrum capricornutum, acute crustacean test withDaphnia magna, acute fish test withBrachydanio rerio), cost-effective acute bioassays have ...

Utility of the laser particle counter for determination of drinking-water toxicity
Particle toxicity in various water samples depends on the mixture of toxicants in each sample. Toxicity values for different samples can be expressed using the new metric: Particle Toxicity. Use of the Spectrex PC-2000 was the instrument of choice in enumerating the particle concentrations for the calculation of the particle toxicity of drinking-water and reference toxicant suspensions. ...
