Methodology for determining toxicity of pesticides to wild vertebrates

The effects of pesticidal contamination of wildlife habitats may be expected to be proportional to the toxicity of the compounds, the rate and manner of application, persistence of the basic chemical and/or any toxic metabolites, and the extent to which these substances are stored in animal tissues or concentrated by successive elements of wildlife food chains.

Persistence of 2,6-Dichlorobenzonitrile in aquatic environments

In two experiments 2,6-dichlorobenzonitrile was added to aquatic systems, and the residue levels were followed for about 6 months. A granular formulation applied to a farm pond at 0.6 p.p.m. produced highest residues in water and fish about 2 weeks following treatment whereas vegetation and soil samples had the highest levels within 1 or 2 days. Residues were still measurable after 188 days. In po
