Modelling and simulation technologies have improved dramatically over the past decade and their applications in toxicity prediction and risk assessment are of great importance. Such approaches will become increasingly necessary as industrial chemicals advance and as new pharmaceuticals enter the market. In this comprehensive discussion of predictive toxicology and its applications, leading experts express their views on the technologies currently available and the potential for future developments. The book covers a wide range of topics including the in silico, in vitro and in vivo approaches being used in the safety assessment of chemical substances. It reflects the growing and urgent need to strengthen our ability to predict the risks posed by industrial and pharmaceutical chemicals in humans. Extensive information on the use of current animal models used for various toxicities and target-mediated toxicities is included. Also discussed are the recently introduced regulatory initiatives.
