Environmental water concentrations of organophosphate pesticides can be expected to fluctuate widely due to use patterns and rapid hydrolysis. This study investigated some relationships of exposure concentration, duration and periodicity to the chronic toxicity of diazinon to flagfish (Jordanella floridae). Effects were compared on the basis of 'exposure units' (exposure concentration x exposure duration). Treatments at equivalent exposure units caused similar overall effects on the test populations regardless of the life stages exposed or exposure duration per se. The hypothesis is proposed that exposure units could be used to estimate the environmental impact of fluctuating water concentrations of organophosphate pesticides over a wide range of concentration, duration, and periodicity.
