That is 70 mg for an adult weighing 70 kg or 10 mg for a child weighing 10 kg. Size is once again a critical factor in determining toxicity. The nature of the adverse effect from a single exposure changes as the dose changes. For some low doses their will be no response. As the dose is increased the victim become uncoordinated, has blurred vision and reduced reaction time.
Higher doses produces slurred speech, further loss of coordination, and convulsions.
Exposure routes Chemicals can be ingested, injected, inhaled, or exposed by skin contact. The dose required for acute toxicity will vary depending on exposure route. These similarities increase the probability that results observed in a laboratory setting will predict similar results in humans.
