What are the methods of toxicity test?

Toxicity tests are divided into two categories that are characterized by the length of exposure to a sample: acute tests measure mortality and last 24, 48, or 96 hours, while chronic tests measure mortality as well as sub-lethal effects such as reductions in growth and reproduction over the course of seven or more days

What are the models of toxicity testing?

Toxicity models have been developed to measure harmful effects of substances on the human organism. Currently, there are three main categories of toxicity models in preclinical research, i.e., in silico, in vivo, and in vitro models [14], and one category in clinical research, divided into three phases [15].
