Terrestrial studieshave been conducted with
soil micoroganaims in a nitrogen transformation assay, earthworms, and
A nitrogen transformation test was performed
according to GLP and OECD Guideline 216. Following a preliminary
range-finding test soil microorganisms were exposed to the test material
at a single concentration of 1000 mg/kg for 28 days. DMH showed no
significant effect on the nitrogen transformation activity of soil
microorganisms at a test concentration of 1000 mg/kg over a 28-Day
The acute toxicity study in earthworms was
conducted according to OECD Guideline 207 and gave a 14-day LC50 value
greater than 1000 mg/kg.
Toxicity to terrestrial plants (Soybean,
cucumber and oat) was investigated in a seedling and emergence study
conducted to GLP and OECD Guideline 208. DMH was tested at nominal
concentrations of 40, 100, 160, 400 and 1000 mg/kg. The lowest EC50
derived was for cucumber which was 990 mg/kg.
