Mould are detrimental to the health of occupants and building structure
Eye irritation, runny nose, sneezing, coughing, nausea and diarrhoea,
Headaches, fatigue, inability to concentrate, constrictions of airways, skin irritations, respiratory congestion, shortness of breath, wheezing, aggravation of asthma
The link between dampness and health is proven.
Their tiny size makes them easy to inhale, but also difficult to find, filter, identify and remove.
The health effects of most species are largely unknown
Fungi share many basic characteristics of genetic makeup similar humans, but the belong to a kingdom distinct from plants and animals.
Moulds are close to the perfect organism.
Hyphae are able to transport nutrients and water across great distances from areas of rich to short supply
They are highly efficient digesters of organic substances (solid, liquid or gaseous)
High degree of environmental adaptability – due to hybridisation, genetic mutation, and environmentally induced non-genetic mutation
Porous materials need to be dried within 48 hours of getting wet or they should be discarded. This includes gypsum plaster board, carpet, insulation and documents.
Aflatoxins are potent carcinogens.
Therefore they evolved resistance to many of the biocides.
