The Environmental Specimen Bank• The Environmental Specimen Bank (ESB Norway) is an archive for the

future. • Samples are collected to preserving the present environmental state,

so that they can be analysed using the knowledge of the future.• There are probably chemicals in use today that will be proven to be

pollutants in the future. The samples stored in ESB can be used to identify the presence of these substances in the environment as early as possible.

• Sampling for ESB started at Zeppelin last winter (December 2013) with a high number of passive samplers for long-term sampling of persistent organic pollutants.

• Same measurements at the Birkenes stations in Southern Norway.• Measurement over 25 years

Following up measurements from 2008 - 2010

These measurements are a continuation of the local air quality measurements 2008-2010 to look at the impact from activities in Ny-Ålesund, local emissions, emissions from ship traffic etc. Data will also be used to look at possible influences on measurements at Zeppelin.Support from SSF
