ABSTRACT

The objectives of large-scale toxicity testing are to obtain information on the biologic activity of chemicals and gain an understanding of how it works. The highly toxic system data tested is used to identify risks and risk management in the context of the production, management and use of chemicals. The amount of LD₅₀, defined as a statistically significant dose that, when tested in a highly toxic test, is expected to cause 50% of animal deaths over a period of time, is currently the basis for the toxic chemical decay. In previous LD₅₀ studies, lab mice and mice were the most preferred species. The result of extensive discussions on the importance of LD₅₀ value and the concurrent development of various processes is that authorities today do not require older LD₅₀ tests involving large numbers of animals. Limitations, consistent dosage process, toxic class method, and up and down routes all point to some simple methods using only a few animals. Efforts have also been made to develop in vitro systems; e.g., it has been suggested that acute systemic toxins can be broken down into multiple bio kinetic chemicals, cells, and molecules, each of which can be identified and calculated by appropriate models. Different elements can be used in different combinations to model large numbers of toxic events to predict risk and classify compounds. In vitro toxicity testing can be used in a limited testing scheme to reduce animal populations, the suffering used and the reduction of animals. Such a method is natural for the development of recent efforts to improve the testing of large toxins using a series of methods, such as toxic procedures and advanced procedures. In addition, in vitro testing can be used in conjunction with other in vivo tests to increase the initial selection volume: in these in vivo tests, the use of the lowest number of potential animals depends on the appropriate selection dose. This option can be improved by performing appropriate in vitro tests prior to any animal tests that were present when considered necessary. Numerous studies have shown a positive correlation between in vitro cyto toxicity data obtained by unrelated cell lines and LD₅₀ data. However, the best toxic system can be caused by a variety of processes. Methods should be found taking toxic kinetic parameters to account where in vivo predictions are based on in vitro data.
