How much cadmium exposure is necessary to develop itai-itai disease?
Studies conducted to estimate the amount of cadmium exposure necessary to develop Itai-Itai Disease found permissible lifetime cadmium intake (LCD) levels for humans to be 1.7 to 2.1 g. When Itai-Itai Disease was first being recognized in just 5% of the afflicted population, LCD levels are estimated to have already been at 2.6 g.
