Various low-toxicity substances are contained in the high functional electronic products in recent years. Although there is a little quantity of low-toxicity substances in each electronic product, total amount of them has been increasing by the mass production of electronic products. This means they tends to diffuse into environment and it also results in the loss of valuable metals. In this work, a substance flow analysis (SFA) on low-toxicity substances in used cellular phones as a typical example of high functional electronic commodity was carried out based on the actual condition of disposal which was acquired by the questionnaire applied to users and composition of cellular phone analyzed by ICP and EPMA. The amount of some scattered low-toxicity substances has been estimated. It was pointed out that establishment of the recycling system of cellular phones including used ones stored by users is very important in the view point of the avoidance of low-toxicity substance diffusion and recovery of valuable elements.
