Chemical hypersensitivity can not return after

Chemical hypersensitivity can not return after

New furniture and, in the perfume of the person who passed each other,
I think you have come better eye was often experience.
In response to hypersensitivity to certain chemicals,
Or a headache or uncomfortable in the eyes and nose
States such as feeling or worse,
This is called chemical hypersensitivity.
Large amounts or over a long period "among researchers
Are exposed to trace amounts of hazardous chemicals, such as receptor in the body
And hypersensitivity to win once, and then very small amounts of
State "clinical symptoms begin to appear in the complex encounter of chemicals and of the same strain
Will most likely be defined.


However, more than half of the people of chemical hypersensitivity,
That develop during the occupancy of new homes
There is also data that, and sick building syndrome
Is often used as synonymous.
That it accounts for many causes of chemical sensitivity,
Indoors, such as formaldehyde and volatile organic compounds
Air pollution is a substance that occurs.
In volatile organic compounds (pesticides and termite repellent) coating material and new building materials,
Does not become careless exterior material.
Volatile organic compounds, and flame on the problem of occupational safety and health course
It can not be ignored, due to indoor air pollution and its
What you should focus on health hazards.


However, volatile organic compounds is very large type,
To set the allowable concentration of each to evaluate the safety,
Is very time-consuming.
In the World Health Organization (WHO),
For each volatile organic compounds typical
As well as its guideline value, the concentration for that amount
Has proposed 300 cubic meters micrograms /.
But even so, the sampling method for measuring the concentration of formaldehyde for example,
Is a situation that is currently proposed in the professional organizations of the International Organization for Standardization.
Based on this situation, the health study group housing,
Formaldehyde, toluene, xylene, wood preservatives,
Material and priority initiatives plasticizer, the termiticides,
Was proposed to achieve the high housing health is low emission of chemical substances.


Side to provide a building is, or plywood that is displayed in the JAS for example, and F1 and
Association of wall covering material, or particle board used in the JIS standard E0
, Such as by reference to the (ISM) voluntary standards for interior materials,
And to select the materials and construction methods with less potential for emission of chemical substances,
Have emphasized the need, such as to the description of the way of living to residents.
In addition, the paint is not used as much as possible such as the development of an organic solvent,
Infancy is a variety of initiatives.
About the toxicity of chemical substances, with respect to acute toxicity has been studied most often.
Has been well studied carcinogen, chronic toxicity, teratogenicity as well as any other.
About the allergy and toxicity, chemical toxicity information for hypersensitivity is however
There is little so far.
"Health effects of fungicide and flame retardant PVC that is included in the wallpaper?"
Also be asked, not quite accurately answer is a shame.
