ChemTHEATRE Site Policy


ChemTHEATRE (Chemical in the THEATRE: Tractable and Heuristic E-Archive for Traceability and Responsible-care Engagement) is a database to deposit and visualize the monitoring data of chemicals in environment.

ChemTHEATRE stores chemical concentrations in environmental specimens with metadata of the samples (sampling date and location, organism and its biometry, and so on) and of experimental methods (extraction method, used standards, instruments, etc.), which make it possible to search the concentration data not only by chemicals but also by sample types, species, sampling places, sampling year, and so on.
