Influence of indoor microclimate distribution on mould infestation in a university library

Indoor mould contamination portends grave consequence to the stored components as well as inhabitants of infested dwellings. Such defilement, which is due to favourable growth environment for micro-organisms, is often associated with Sick Building Syndrome (SBS) and other Building Related Illness (B...
