4. Description of Major Analytical Results.
For your convenience, following is a brief description of our major analytical findings General characterization is made with respect to the most common known health effects of the various species of the identified genera.

Airborne particles as Total Suspended Particles (TSP) concentrations represent the largest range of particles, including those which are respirable (as small as 3 micron and less) and can reach the alveolar area of the lungs, and thoracic (less than 5 micron), which can reach the trachea and all the airways and those between 5-10 micron (inhalable), which can reach only the inside of the nose, mouth, trachea and upper airways, but cannot reach the gas-exchange areas in the lower lobes of the lungs. Besides the potential health effects on exposed individuals, TSP have the physical quality of carrying and dispersing odors and odorless gases generated by an interior source, such as work stations, office equipment, building materials, carpets, wallpapers, etc. The range of the particles we tested was: 0.3 microns (), 0.5 , 1.0 , 2.5 , 5.0 and 10.0.

How long particles remain airborne, before their sedimentation on interior surfaces, depends on their size and weight: if for particles of 1 it takes 4 hours, and for 0.3particle 5-6 days, 10.0 particle will take only 3 minutes. Heavier particles larger than 10.0 fall down and are deposited on interior surfaces and released into the air when disturbed in the process of human activity. They are removed by cleaning, as TSP (below the size of 1 0.0 particles) can be primarily eliminated by means of ventilation and filtration.

Particles under 1 m in size normally constitute 99.9% of the number of particles in room air, and have a mass, which make up ca 30% of the total mass. The movement of particles in air is also affected by their charge and the presence of electric fields. For particles of the order of 1m, their charge and the presence of electric fields are of significance, for e.g. particle deposition on the skin, while deposition of larger particles is governed by air movements. Dust indoors contains a large amount of specific allergens. It is an indisputable fact that an elevated particle content in air increases the load on the airways, and that at the same time these particles may be carriers of specific irritating and allergenic agents. The particle content of air should therefore be kept low, i.e. elimination measures such as good cleaning and good ventilation (inclusive of good filtration of supply air).

Using the Enviroboot model EB1 reduce significantly the level of the Respiratory Suspended Particles (RSP)"

Product Testing

On May 25, 2006, we conducted air samplings in the interior basement area at a residence in Carmel, New York

  1.     Methodology

  2.     Testing involved the collection of four (4) air samples.

The following is a brief description of collection media used in this survey: Air-O-Cell-Air sampling cassette manufactured by Zefon International, St. Petersburg, Florida, USA is a sampling device connected to a micro-pump that draws 1 5L/min of indoor air into the cassette, onto a slide, designed to collect airborne particles.

  1.     Particle measurement uses LIGHTHOUSE HANDHELD 3016 Particles Meter.
  2.     Visual inspection and Observation.,   Olympus Digital Camer

3. Results The major analytical results are presented as follows:

3.1 Airborne particles ID

3.1.1 Air Sample # 1 collected when ESS technician perform demolition job using an electric breaker hammer and using the Enviroboot model EB 1 (see photo # 1) connected to HEPA vacuum cleaner.

3.1.2 Air Sample # 2 collected when ESS technician perform demolition job (see photo # 2).
