RESUMO
In the early 1950s,China′s modern industry and national defense developed rapidly. While toxicological research,represented by occupational toxicology,radiological toxicology and military toxicology,was initiated. Along with the expansion of industrial and agricultural activities and production, high- speed economic development,and the changes of the environment and lifestyles,the objects and content of toxicological research have also been expanded. Subdisciplines of toxicology have kept emerging,and an integrated toxicological discipline and research system has been established. Toxi?cological research has become an active area in China. Toxicological publications from China have accounted for about 10% to 20% of total international toxicological research papers in the recent ten years. Toxicologists in China have paid much attention to the toxicities and biological safety of new materials and emerging pollutants,such as nanomaterials and fine particles in the air. Some toxicological research was discussed in this paper.
