Data management
All data will be handled strictly confidentially and in accordance with the guidelines of the EU General Data Protection Regulation. All procedures with regard to handling of the data are described in a Data Management Plan, which is submitted to the grant provider ZonMw.Data used for analyses is pseudonymized after data collection, by giving each respondent a respondent number. The list of names with respondent numbers is kept separately from the research data. All digital data is stored in a secured vault at (TNO) SharePoint Online, with access restricted for project members only. The data is located within the European Union (Ireland and the Netherlands). Access to the information is only possible through Multi Factor Authentication. TNO makes a daily back-up of the information. Both for SharePoint Online and for the backup use is made of encryption 'in transit' and 'at rest’. Paper questionnaires are marked with the respondent number. After completion, the papers are scanned and subsequently destroyed. The answers are entered into the digital datasets. Both the scanned questionnaires and the datasets are stored in the secured vault at (TNO) SharePoint Online as described above. Collected hair samples are marked with the respondent number, and are securely stored in areas with limited access, both at the PCH locations and at TNO until the samples are sent away to the lab (Dresden LabService GmbH) to be analyzed and subsequently discarded.
