Advances in alternative methods upon the vision for toxicity testing in the 21st century / 中华预防医学杂志

ABSTRACT

With the increase of global chemical production and the aggravation of population exposure and health risks, higher requirements are put forward for chemical toxicity testing and safety evaluation.'Toxicity testing in the 21st century: a vision and a strategy' has greatly promoted the reform of toxicity testing. Toxicity testing in the new era has made great progress by using new models, new methods and new strategies, combined with interdisciplinary and high-tech advantages. While improving the efficiency of chemical toxicity testing, it also realizes more comprehensive, multi-level and high-quality data acquisition and toxicity evaluation, which provides strong support for the exploration of toxicity mode, toxicity mechanism and toxicity pathway. Focusing on the current alternative new methods of toxicity testing, this issue invites many scholars to introduce and summarize high-content analysis, three-dimensional (3D) cell culture technology, Ex vivo test, single cell sequencing and zebrafish experimental methods, in order to promote the leapfrog development of chemical toxicity testing and evaluation in China.
