The Development of Neurobehavioral Toxicology in China: The 1994 Hänninen Lecture

With the rapid growth of industrialization in China, occupational and environmental exposure to chemicals has increased in frequency and in types of chemical exposures. A growing number of Chinese researchers are showing a special interest in exploring the effects of chemicals on the central nervous system. This paper presents a comprehensive review of neurobehavioral toxicology in China. It describes research into the “reference values” of the Neurobehavioral Core Test Battery (NCTB) tests, the development and improvement of the computer-administered Chinese version of the Neurobehavioral Evaluation System (NES-C), and exploration of related biomarkers. On the basis of this research, baseline data for the reference values for six subtests of the NCTB were preliminarily recommended. The upgraded NES-C2 has proven to possess higher stability and validity compared with the previous version, NES-C. Biomarkers derived from the changes in levels of neurotransmitter metabolites might be used as supplementary biomarkers of Pb-induced neurotoxicity.
