PREVENTIVE CONSERVATION OF CULTURAL HERITAGE

Rene Van Grieken

Resumo


Preventive conservation implies, amongst many other aspects, the characterization of the atmospheric environment around monuments or cultural heritage (CH) items, with the intention to improve the conditions and to contribute to the preservation. We have, over the last two decades, intensively used various forms of X-ray spectrometry and automated electron probe X-ray microanalysis, always together with ion chromatography, micro Raman analysis, on-line soot determinations, gravimetry, etc., to identify particle types and their sources in indoor environments, including museums, while also gaseous indoor pollutants were assessed. The cases studies outlined in the present paper concern the Wawel Castle, in Cracow, Poland, the Alhambra complex in Granada, Spain, and the Plantin-Moretus Printing Museum in Antwerp, Belgium. Some questions that are presently far from having been solved pertain to the deposition processes from the atmosphere to the CH items and the critical surface interactions that take place on
the CH items

CONSERVAÇÃO PREVENTIVA DO PATRIMÔNIO CULTURAL


RESUMO

Conservação preventiva implica, entre diversos outros aspectos, a caracterização do ambiente atmosférico ao redor de monumentos ou objetos de patrimônio cultural (PC), com a intenção de melhorar as condições e contribuir para a preservação. Nós temos, nas últimas duas décadas, utilizado várias formas de espectrometria de raios-x e sondas eletrônicas automatizadas com microanálise de raios-x,sempre em conjunto com a cromatografia iônica, análise micro Raman, detecção on-line de fuligem, gravimetria, etc., para identificar os tipos de partículas e suas fontes em ambientes internos, incluindo museus, onde também foram encontrados gases poluentes. Os estudos de caso do presente trabalho estão relacionados ao Castelo Wawel, na Cracóvia, Polônia, o Complexo Alhambra em Granada, Espanha e no Museu Plantin-Moretus na Antuérpia, Bélgica. Algumas questões aqui apresentadas que ainda estão longe de terem sido solucionadas, remetem aos processos de deposição da atmosfera para os itens do PC e as interações superficiais críticas que ocorrem nos objetos do PC.
