物質ストック勘定による金属の環境中への排出量推定とリスク評価

抄録

The objective of this study is to quantify material flow and emission of nickel and antimony as an example of material stock accounting of chemicals. Also, human health risk assessment of antimony from the air is conducted based on the result of material stock accounting. As a result, it was revealed that the emission of nickel from production and processing stages was the main source, and the emission of antimony from stock and incineration was the main source. Furthermore, it is low possible of human health risk of antimony in Japan. The current study showed the usefulness of material stock accounting applied to risk assessment.
