Experimental evaluation of the growth rate of mould on finishes for indoor housing environments: Effects of the 2002/91/EC directive

We report the results of a study to evaluate the growth rate of three species of mould on plasters, finishes and paints typically used in structures with heavy weight building envelopes. The aim was to determine the influence of the chemical composition (in terms of organic fraction of the materials) on the growth rate of moulds. The study was carried out in the following steps: – characterization of materials; – inoculation of mould spores (3 species) on 7 types of material (2 plasters, 3 finishes, 2 paints); – growth in a climatic chamber (23 °C and 90% RH); – analysis of the mould growth rate using various experimental techniques (fluorescence microscopy analysis, thermogravimetric analysis, etc.). Results show a clear correlation between the organic substances contained in paints, plasters and finishes and the growth rate of the mould.     

生物洁净技术若干误区辨析

对生物污染因子控制与生物净化经常遇到的一些认识上的问题进行了探讨。认为如不解决这些问题就难以对微生物污染实施更有效控制,也难以将我国微生物控制与生物净化的研究提高到一个新的水平。
