Effects of lowered dissolved oxygen concentration on the toxicity of 1,2,4-trichlorobenzene to fathead minnows
The primary objective of this study was to determine if the dissolved oxygen (DO) concentration affects the toxicity of 1,2,4-trichlorobenzene (1,2,4-TCB) to fathead minnows, Pimephales promelas, exposed during the embryonic-to-larval-juvenile development stage. This stage in the growth of the fathead minnow and several other species of fish has been found to be the most sensitive, or among the most sensitive, to chemical pollutants in life-cycle toxicity tests. The chemical 1,2,4-TCB has been identified as a priority pollutant by the US Environmental Protection Agency. It is used as an intermediate in the synthesis of a number of herbicides and insecticides and has been found as a contaminant in fish. It was selected as the chemical stressor in this study in order to provide information useful to the Agency in deriving water quality criteria for the protection of aquatic life.
