DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a process for decontamination and detoxification applied to sanitary engineering in the home.
The technical sector of the invention and its application are in the domain of hygiene and sanitary engineering in the home, for domestic purposes.
2. Description off the Related Art
The terms ecology and environment have become commonplace especially concerning nature, but their definition should also include the study of the home: in fact, it may be noted that the word "ecology" comes etymologically from the Greek word "oikos", meaning house and "logos", science. Moreover, this home is contaminated by all sorts of so-called live particles which are responsible for a specific pathology, named "domestic lung" in the publication and conference made by Messrs. Michel BLANC and Bruno BLAIVE at the Versailles "Forum Contamine Expert" on 13th, 14th and 15th Sep. 1989; this term has been defined as grouping together the pathological states due to the multiple aggressors of pollution inside homes, provoked both by the components of the house dust produced by animals, plants, bacteria, insects, pollens, mould, viruses, etc., and which create biocontamination, and by the particles issuing from the combustion of tobacco and products coming from the outside due to industrial combustion and to automobile traffic.
There is addition and interference between these very diverse particles in the sense of added, pathological, deleterious effects, involving, for example particles from combustion and biocontamination. This also is the case for the particles of tobacco and mould, namely nicotine and acarids.
It should be noted that the contamination of the inside atmosphere also depends on the contamination of the outside atmosphere, that it is bound thereto and that it is always greater.
This contamination is different from biocontamination, as it is physical (rare gases, electro-magnetic elements, etc.) and chemical (industrial combustion, SO.sub.2, NO.sub.2, etc.). It further interferes in the configuration of the particles of the domestic ambient air, which the human being inhales at a rate of 800 millions of particles per day, of which the major part is absorbed by the organism.
Their quality and quantity are such that, normally, they are not noxious, sometimes even the contrary. However, when they fix toxic and/or contaminated additives, when they are concentrated in a large quantity (which is the case in confined, poorly ventilated dwellings), then their inherent toxicity is apparent.
These particles are in particular generated by the ejections of acarids, themselves raised in a composite, mutant culture medium.
Acarids make a veritable compost of house dust, in the same way as those of the forest make humus. They find in the dwelling a biotope which is always propitious, coming from numerous factors already cited, and in particular the conditions of temperature and humidity favourable to their development, all the more so in modern dwellings, in particular in the bathrooms and ventilation systems.
There is a veritable permanent recycling by the acarids of the particles thus generated which are then concentrated by them; it is admitted that the major allergen of "domestic lung" is contained in the ejections, "specks", of acarids. The semi-quantitative colorimetric dosage of nitrogenous metabolite guanine is a veritable index of contamination of house dust, whilst being specific of its presence. This test is thus found positive in dust in carpentry workshops and bakeries, in henhouse dust, and in house dust: there is thus a good correlation between this test and the clinical manifestations associated with allergies to house dust and acarids.
Now, the constant threat of a respiratory pathology associated with the inhalation of particles is progressing in a disquieting manner, whereas curative treatments have never been as widely employed and as efficient. This paradoxal failure may be explained by ignorance, by a deterioration of elementary hy
