The Estimation for the Handling Amount of Chemicals by Utilizing PRTR Data

Abstract

Disaster assessment requires preliminary evaluation of chemical risks for specific target areas in a given location. Accidents require knowledge of the type of chemicals, handling amounts, the underlying possibility of emissions leaked, and potential issues caused by release. Herein we obtained data on chemical handling amounts from several local government offices. We analyzed the data in detail to determine the relationship between the release-transfer amount and the handling amount, namely the emission-transfer rate. Moreover, the handling amount was estimated across Japan using open PRTR data on the emission-transfer rate.
