93Impact assessment on organic
material – problems to be solved In museums and
historic buildings all over Europe, objects made of organic materials are being affected either by display or by storage conditions because of unsuitable environmental conditions.

93The Main Aim of the Project
To provide conservator staff of museums, historic buildings and archives with a new preventive conservation strategy for the protection of cultural property, based on an early warning system assessing the environmental impact on organic objects.
Up to now there has been no early warning tool for organic materials.

Target institutions and responses
European museums, historic houses and archives were sent questionnaires to approx. 100 institutions
31 institutions of varying size from 18 different countries responded, from Finland to Malta, and Portugal to Hungary

93Development of an Early Warning
System Assessment of environmental factors not
enough in order to understand the real effect on art objects
The knowledge of the actual reaction between the art object and the contaminant is crucial
Development of sensors which emulate the reaction between art objects and the contaminants and which give a measurable effect responce will be a useful Early Warning System

93Development of the Early Warning
Sensor (EWO-sensor) Different organic polymers have been tested The intention is to develop a sensor that can
indicate the rate of chemical change, or damage, that objects are likely to suffer in a particular storage or display environment.
The main processes of chemical deterioration for organic objects involve either oxidation or acidic processes, or possibly a combination of both.

93 The Early Warning Sensor (EWO-
sensor)
The EWO sensor is manufactured by spin coating the polymer onto a glass carrier. The production of EWO sensors is made by the partner Freiburg Material Research Centre
Chemical deterioration of certain polymers has shown to be detectable by simple techniques such as uv-visible spectrometry.

Tasks:1. Laboratory test: EWO response to controlled conc. of NO2, O3 and SO2. - Calibration
2. Field test: EWO response to measured conc. of NO2, O3 and SO2 in the museums.- Compare with lab. test. - Relate to real objects.
