Activating a GIS application as an auxiliary tool for environmental forensic is based on high-quality data. Therefore, the objectives of this project are not only enhancing the existing auxiliary tools but building up a traceability system of sample lifecycle. Traceability system of sample lifecycle is a concept of collecting all the information from processes of environmental contamination analysis, and to manage accredited laboratories with it. It contains application system, mobile platform and management system. The significant difference from PSN is to fill out a sampling information file. Sampling information file can be developed from an embryonic form to a specification filled with data. While a sampling trip is carrying out, the sampler can use the mobile platform to get a coordinate of the sampling site and record the time automatically. The sampling positions and time could be checked by using distance and delay. In addition, in-situ sampling process filming and sample tracking code are tested practically and gave suggestions for operating. Manufacturing process information of pollution sources was included in a new auxiliary tool. It complements raw material information completely. To keep auxiliary tools of environmental forensic working well, data updating was carrying on for the duration of the project. In sum, to build up a data structure with high quality and high applicability, the project in this year is with the aim of improving intensifying accredited laboratories management. Traceability system of sample lifecycle is a more complete structure to manage accredited laboratories. In a long-term, it can give both a nice database and high applicability for forensic.
