3.2 Environmental factors
The five critical environmental factors for the growth and development of mold in library collections are:
- The presence of mold spores
- A source of nutrients
- Adequate moisture
- Suitable temperature for a particular variety of mold.
- Limited air circulation
It is obvious that the first two factors are completely beyond the control of librarians. The presence of spores and the source of nutrients are a given in library collections. Only the last three factors can be manipulated or controlled in order to prevent the occurance of mold growth.
