Contaminated HVAC Ducts: Fungal Growth And Its Role In Indoor Air Problems

One recent study, which looked at hundreds of duct liner samples taken from “problem buildings,” found that nearly half of the samples were contaminated. This presumably means that contaminated material was left in place until it either caused or contributed to ongoing IEQ problems – problems severe enough to trigger an investigation. The conventional wisdom …

Biocides In Textile

Any unwanted modification in the properties of a material brought about by the essential actions of organisms is called Bio-deterioration. Present article is concerned with the degeneration of textile materials produced by microorganisms like fungi and bacteria, and the solutions to avert or reduce their effects. Not all failures of materials by microorganisms are unwanted. …
