ENVESOME Harmonized Data Dictionary and Codebook

The codebook provides a harmonised data dictionary and standardized metadata for variables collected across the ENVESOME human studies, supporting consistent data collection, management, harmonisation, and integration across participating cohorts. This resource is intended for use by ENVESOME consortium partners and the wider scientific community as a reference for data harmonisation, metadata standardisation, and FAIR data management in exposome and human biomonitoring research. Future versions may include additional variables, updated coding schemes, and expanded metadata as the project evolves.
