In an acute inhalation toxicity study (MRID [number]), groups (#/sex) of strain, species (source), (age, weight) were exposed (nose only, head only or whole body) via the inhalation route to (formulation, note a.i. and %) in (name of vehicle or undiluted test article) for [#] hours at concentrations of , , or mg/L. Animals were then observed for [#] days.
LC50 Males = mg/L (95% C.I. if available)
Females = mg/L (95% C.I. if available)
Combined = mg/L (95% C.I. if available)
