Textile ageing due to atmospheric gases and particles in indoor cultural heritage.

Textile fibre degradation can be due to many factors. The most common cause is light exposure, but upon the lifespan of a textile, many other environmental factors are to be taken into account. This study focuses on the role of atmospheric compounds-both particulate and gaseous species-on natural textiles ageing, more specifically cotton, silk and wool.

Assessment of indoor air quality for a better preventive conservation of some French museums and monuments.

Indoor air quality in museums and historical buildings is of great concern for curators, since it can be a source of various alterations on artworks. In spite of their importance, very few studies study simultaneously the concentration of main gaseous pollutants, the composition of suspended (PM), and deposited (DPM) particulate matter. The aim of this article is to carry out a first environmental assessment in French museums or monuments.

Water content of limestones submitted to realistic wet deposition: a CIME2 chamber simulation.

An experimental chamber (CIME2) has been specially designed to simulate wet atmospheric deposition on limestones used in Paris cultural heritage. This instrument is a complementary tool to CIME, a previously developed chamber dedicated to the simulation of dry atmospheric deposition on monuments and artifacts. The aim of this paper is to describe CIME2 and characterize the wet deposits produced inside it.
