Test Results for Air Bacteria   Test taken in office envelopment. These tests were taken from Airplates used to Moasure Bacreia and Mould in the air.The plates were placed around a room 10m x 5.5m x 3m. The Air plates were left for 30 minutes for accurate results.  The Ozone Generator was left on over night & the same procedure was done with the Airplates again the next morning. In the first test there was a high bacterial count and a high mould count. As seen on page 1 of 1    In the second test [Ozone Generated] The bacterial was drastically reduced and the Mould was totally destroyed.                                                                          Bacterial Kill The File Cabinet   65%  Bacteria Kill Rate The Green Table    87%   Bacteria Kill Rate The Wall C           54%   Bacteria Kill Rate The Side Table     78%  Bacteria Kill Rate The Moulds         100%   Destroyed Tests done by Swift Laboratory

Background to VOCs                VOC’s such as solvents, e.g., n-butyl acetate, iso-butylacetate, and formaldehyde, are emitted From the sealing of wooden parqueted floors with coatings, which is worsened by having the Windows closed during the coating process. Paints, lacquers, varnishes and adhesives are major emitters of VOC’s. Moisture repellents contain white spirit which is a solvent and releases VOC’s. Liquid process photocopiers in offices can cause problems by emitting mostly isodecanes. Benzene is a commonly used solvent and is found in gasoline, inks, oils, paints, plastics and rubber and is used in the manufacture of detergents, explosives, dyes, and pharmaceuticals. More than 90% of trichloroethylene is used in the metal degreasing and dry cleaning industries; it is also used in printing inks, paints, lacquers, varnishes and adhesives. Cleaners and products [e.g., adhesives, floor cleaners, waxes, deodorizers, carpet cleaners, furniture polish] emit large amounts of many VOC’s, such as, ethanol, butanol, anyone, formaldehyde, methyl – ethyketone, toluene, dimethylbenzene, cleaners and products [e.g., adhesives, floor cleaners, waxes, deodorizers, carpet cleaners, furniture polish] emit large amounts of many VOC’s such as, ethanol, butanol, acetone, formaldehyde, methylethlketone, toluene, dirnethylbenxenc, a-pinenc. 1.4 dichlorobenzene and many more. Consumer products like plywood boards, polystyrene insulation board, polyvinyl floor covering and polyvinyl coated wallpapers, emit similar VOC’s such as xylene, toluene, ethyl benzene, styrene and methyl acetate. Carpets are another major source of VOC’s, the alcohols 2-ethyl-1-bexanol and heptanol, are emitted by PVC backed carpet. Vinyl floor coverings emit high levels of semi-volatile organic compounds and even after several years the compounds are still found in high levels. Health and beauty aids have very high concentrations of benzene, styrene, trichlorethylene and ethyl benzene. VOC’s can be very toxic. They have been reported to impair cognitive function, irritate mucosal membranes in the eyes, nose and throat, cause headaches, mental fatigue respiratory distress and mental confusion and fatigue.                VOC mixtures also cause headaches; drowsiness, nose, throat and eye irritation and they induce an inflammatory response in the upper airway. Individual VOC’s at different concentrations and different forms of exposure can have various effects on human health including causing cancer. Benzene is considered a human carcinogen and causes leukemia: trichloroethylene is a potent liver carcmogen; carbon  Terrachloride and dichloromethane are probable human carcinogens; chloroform: is a suspected carcinogen, and many others are being evaluated by the EPA for evidence of human carcubigenic potential. The following are examples of VOC’s and some of the symptoms they can cause: xylene is a central nervous system depressant that produces headaches, lightheadedness, nausea, conjunctivitis, nasal, respiratory and throat irritation . and loss of coordination; chloroform is an irritant, central nervous system and cardiac depressant and corjunctivids may occur from exposure to vaporus; styrene is irritating to the eyes, respiratory and gastromtestinal tracts and skin, and central nervous system depression may occur; repeated skin contact with benzene will cause inflarnmation. Drying, blistering and dermatitis; carbon tetrachloride vapour is a narcotic and causes severe damage to the liver and kidneys, also causes nausea, headache, dizziness, confusion, drowsiness. And visual distrubanees; and tetrachlorocthylenc can cause dizziness, headache, verugo, unconsciousness, and light central nervous system depression. Methods                Tests were carried our before and after the Airpure was turned on in 3 locations that are likely to experience high levels of VOC’s. Location used were a print shop: Low flow pumps were used to draw air through the activated carbon tubes at 0.5m/minute for periods of 4 or more hours during the operations. Concentrations collected in the tubes was then desorbed by dichloromethane and then analysed using GGMS. Results from the GCMS were then calculac, hosing and total number of litres drawn through the pumps and converting that into came methods. The hotel was a large establishment with an adjoining TAB. It had a long bar and the monitoring equipment was set up on a shelf above the center section of the bar. The hotel patrons were a mixture of smokers and non-smokers. The bar was section was full but not crowded. There was no smoking in the TAB section which was a separate room although it was not physically sectioned off from the me it bar and longe. The bar manager reported that the morning after monitoring took place, the smell of stale beer and cigarette smoke was noticeably reduced                Results    Table 1.

Hurricane is an efficient method of removing voluble organic compounds from the air in bum such as nail clinics where VOCs might be a problem.
