Chemical Allergies & Sensitivities

 

We can classify chemical sensitivity in four general ways:

 
 
 
Annoyance Reactions.
 

Your ability to deal with offensive but mostly non-irritating odors has a lot to do with genetic or acquired factors, among which are infection and inflammation of the mucous membranes or polyps (growths of the nasal or sinus membranes), abuse of tobacco and nasal decongestants.

 

Then, Annoyance reactions result from olfactory awareness in some susceptible individuals, which is a heightened sensitivity to unpleasant odors.

 
 
 
Irritational Syndromes.
 

As it name implies these types of reactions can affect certain nerve endings and cause irritation or a burning sensations in the nose, eyes and throat.

 

Irritational Syndromes are caused by significant exposure to irritating chemicals that are more likely than others to penetrate the mucous membranes. They usually come and go, and can be reversed.

 
 
 
Immune Hypersensitivity.
 

This type of sensitivity is generally caused by naturally occurring organic chemicals found in pollens, molds, dust and animals. It is the basis of allergic diseases, such as allergic rhinitis (hay fever) and asthma.

 

Currently, only a fairly quantity industrial chemicals are known to have the capability of creating a true immune system response. Among them are acid anhydrides, isocyanides and other chemicals that are able to bond to human proteins

 
 
 
Intoxication Syndrome.
 

Toxic substances are given off by a number of building products, such as furniture, cleaning fluids, pesticides and paints.

In some cases, long-term exposure to noxious chemicals may cause serious illness, or even death.

 

Permanent damage to health may be the outcome of such reactions, which are dependent on the nature and extent of the chemical exposure.

 
 
 
How Does Pollution Affect My Health?
 

Outdoor pollution may be the consequence of natural causes such as the eruption of volcanoes, dust storms, forest fires, or man-made causes including vehicle exhaust, fossil fuel combustion, and petroleum refining. The majority of people who believe they have symptoms from chemical sensitivity are concerned that they are related to their exposure to pollution, either outdoors or indoors.

 

forest fires), or man-made causes (vehicle exhaust, fossil fuel combustion, petroleum refining). Other pollutants that may cause respiratory illness include:

 
 
 
Sulfur Dioxide
 

People prone to allergy, especially those with allergic asthma, can be particularly sensitive to inhaled sulfur dioxide.

 

Symptoms may include bronchospasm, hives, gastrointestinal disorders and inflammation of the blood vessels also known as vasculitis-related disorder.

 
 
 
Ozone and Nitrogen Dioxide
 

It’s known that long-term exposure to nitrogen dioxide is associated with the increased occurrence of respiratory illness. Moreover, inhaling ozone and nitrogen dioxide might be the cause of temporary or perhaps permanent bronchial hypersensitivity.

 

High exposure to airborne pollution take place inside homes, offices and non-industrial buildings; however these settings have not received nearly the attention by pollution control agencies that they deserve.

 
 
 
Cigarette Smoke
 

Cigarette smoke is one of the most disagreeable and potentially dangerous indoor pollutants. Numerous chemicals are used in the mixture of gases and particles that compose cigarettes. Indoor tobacco smoking substantially increases levels of carbon monoxide, formaldehyde, nitrogen dioxide, acrolein, polycyclic aromatic hydrocarbons, hydrogen cyanide, and many other damaging substances.

 

Formaldehyde is found indoors from cigarette smoke, as well as in outdoors from gasoline and diesel combustion. Despite the fact that there is no convincing evidence that formaldehyde is able to sensitize the respiratory system, research indicates that this pollutant is capable of acting as a respiratory irritant and it also is known to cause an allergic skin rash.

 
 
 
Wood burning Stoves
 

Now-a-days more than 11 million wood burning units are present in American homes. Increased use of wood as a heating fuel has raised concern because of its ability to contaminate a home.

 

Increased use of wood as a heating fuel has raised concern because of its ability to contaminate a home. Poorly ventilated stoves give off increased levels of carbon monoxide, nitrogen and sulfur oxides, formaldehyde and benzopyrene.

 
 
 
Building-related Illness
 

Poor air quality in nowadays homes and buildings has been linked with a diversity of group of symptoms or syndromes. The term "building-related illness" or "sick-building syndrome" refers to an office building in which one or more occupants develop a generally accepted, well-defined health condition for which a specific cause related to the building is found.

Hypersensitivity pneumonitis is part of a variety of illnesses in which one or more organic dusts can create complex immune system reactions and symptoms, including mucous membrane irritation, coughing, chest tightness, headache and fatigue.

 

 

Building occupants with these symptoms have been identified as having "multiple chemical sensitivities" or other forms of environmental illness. These illnesses are well defined, and there are validated tests for diagnosing these conditions.

On the other hand, studies have proven that the majority of nonspecific complaints by office workers had developed before the worker began working in the building suspected of causing their symptoms. Cooperation between the physician, industrial hygienist and building engineer may be necessary to clearly establish a cause-and-effect relationship between any indoor air quality level and disease.

 
 
 
How is Chemical Sensitivity Diagnosed?
 

Some of the approaches that can produce reliable diagnoses with relatively low cost, include:

Patient medical history that take account of all previous medical records.
  If symptoms are related to potentially hazardous substances in the workplace, a Materials Safety Data Sheet supplied by the employer is required.
  Upper respiratory tract , selective skin tests and a neurological examination.
 
  Routine laboratory studies, including nasal smear.
  Spirometry and peak flow monitoring (lung function measurements)

The diagnostic procedures may not produce a definite diagnosis; however, other evaluations may help. They include an industrial hygiene evaluation of the workplace, an evaluation of the home environment and psychiatric evaluations. These types of assessments are usually more expensive, but worthwhile
