title: MESOCOSM database for environmental NanoSafety

description: MESOCOSM database contains experimental data collected from mesocosm experiments suited for understanding and quantifying both the environmental hazard and exposure of Nanomaterials, in order to better explain ENMs behavior and potential impacts at different phases of ENMs lifecycle. The experiments investigate Ag, CeO2, CuO, TiO2-based ENMs as well as nano-enabled products. The database is downloadable in SQL format, and its structure is described by the conceptual data model that is also available. The database contains six tables : table "Reference" contains information about the articles that describe the experiments at the origin of the data ; table "Ecosystem" gives the details about the ecosystem in which each experiment has been conducted ; table "Contamination" informs about the contamination scenario of each experiment and provide details about the physical and chemical properties of the nanoparticle used as a contaminant ; tables "Environmental_Endpoints", "Exposure_endpoints", and "Hazard_Endpoints" respectively contain the indicators for assessing the state of the environment, the parameters used to measure the exposure of the studied environment to the contaminants, and the biomarkers used to measure observable changes indicating the hazard of the contaminants towards living organisms. The used units of mesures that have been used are listed in the "Additional notes" section. Articles describing the experiments at the origin of the data are listed in the "References" rubrique. The DOIs of these articles are also available in the table "Reference" of the MESOCOSM database, and linked to the experiments results' records through the table "contamination".
