ERASM (www.erasm.org), with support of the Institute for Environmental Studies of the Free University of Amsterdam (IVM), has further developed the user-friendly CEFIC-LRI database ‘MonitoringBase’ to store metadata and actual measurements from surfactants in the environment across Europe. This has enabled ERASM to create a legacy of its work, as well as to demonstrate leadership of the detergent industry by providing information to external stakeholders. MonitoringBase Surfactants is implemented in Microsoft Access 2000, which enables all information to be managed from a single database file. The various types of monitoring programmes and measured concentration data were entered into separate tables for each specific data type. Reports of retrieved data were designed for export to Word documents, Excel worksheets or for printing directly.
