Altistustietoon

Altistustietoon is a term describing a proposed standardized model for recording and exchanging information about exposure to chemical, biological, or physical agents. In occupational health and environmental science, it refers to a structured dataset intended to capture who was exposed, to what, under what conditions, when, and how the exposure was measured or estimated. The aim is to enable interoperability across studies, agencies, and industries by using consistent terminology and data types.

The core data model would include entities such as ExposureEvent, Substance, Measurement, Unit, Method, Location, PopulationGroup, TimePeriod, and Source. Each record should include provenance information (data source, collection method), quality indicators, and links to external identifiers (such as chemical identifiers or exposure limits). The model emphasizes controlled vocabularies and harmonized units to support cross-dataset queries and meta-analyses.

Applications include integration of monitoring data, workplace hygienic assessments, epidemiological research, and regulatory reporting. Altistustietoon would support exposure assessment workflows, hazard characterization, and cross-study comparisons by providing a common schema for capturing dose, duration, frequency, and context.

Governance and standards considerations involve alignment with metadata and exchange standards, data privacy and consent for human subjects, and ongoing curation to accommodate new measurement techniques and chemical substances. Challenges include heterogeneity of methods, incomplete records, and varying regulatory requirements.
