'ARA-CoSSSLs' risk analysis approach (on a computer worksheet basis) for contaminated sites: implementation and case study application

摘要

Within the increasing attention to absolute risk analysis at Italian level, as a University research study, the definable "ARA-CoS SSLs" approach for human health ("Absolute Risk Analysis for Contaminated Sites", on "Soil Screening Levels" basis) has been derived (as an initial, simplified version) and directly implemented on a series of interactive computer worksheets. The basic conditions of the "ARA-CoSSSLs" approach derivation are: 1) the predominant reference to a fundamental international scientific protocol, also considering its temporal evolution (the US.EPA "SSLs"); 2) a modular, open, common for users, and easily extensible computer calculation. This paper reports on the basic aspects and the specific calculation structure of the "ARA-CoSSSLs" approach; additionally, a simplified case-study application is summarised.
