Considering basic concepts of preventive preservation and measuring the most important influential indicators in proposing an optimum method for preservation and maintenance of historical and cultural works, this paper tries to present methods for proper preservation of historical-cultural works existing in the repository of Malek National Museum.
The effects of environmental conditions including relative humidity, temperature, light, gas pollutants and solid particles in the environment of the Malek National Museum and also the consequences of these factors such as acidity changes in paper works, and the effect of fungi and proper environmental conditions for the development of microorganisms have been experimentally investigated. The aim of conducting these experiments was to compare the extent of each environmental factor in the environment of the repository room of the museum with the standards for environmental conditions in the Malek National Museum and to eventually determine the damaging factors in this museum. To do so, all influential environmental factors such as light, relative humidity, temperature, environmental pollutants, and microorganisms were monitored in a specific time range using instrumental analysis methods.
