Description of key information

An early life-stage toxicity test was conducted in fathead minnow in accordance with FIFRA Guideline 72-2. DMH was tested at nominal test concentrations of 7.5, 15, 30, 60 and 120 mg/L eqivalent to measured test concentrations of 6.8, 14, 29, 55 and 116 mg/L. Fish dry weights were significantly decreased in the 29, 55, and 116 mg/L treatment group and therefore a NOEC of 14 mg/L was determined.
