What are the types of toxicity?
Toxicity is usually divided into two types, acute or chronic, based on the number of exposures to a poison and the time it takes for toxic symptoms to develop.

Toxicity testing is paramount in the screening of newly developed drugs before it can be used on humans. Toxicity testing is the determination of potential hazards a test substance may likely produced and the characterization of its action, most of the toxicity testing is carried out on experimental animals[1].

Hazard Assessment | Toxicity Testing Overview | AltTox.org
Conventional toxicity testing relies on direct toxicity assessment in whole organisms (algae, shrimp, sea urchins, fish, rats, etc.) (Blaise and Férard, 2005). The organisms are exposed to the chemical(s) or mixture(s) of interest and monitored for any sign of adverse health effect.

17.To extrapolate animal testing to humans, it has been found that a)using monkeys provides very similar toxicity results as those shown for humans b)there is no animal species that simulates human responses well, but, generally, testing several species lead to reasonably good estimate of human toxicity.
