Abstract: 

Rationale

Allergy and Asthma cases have doubled in Texas Panhandle area since 2007. We have collected aeroallergen samples and characterized for 14 years. We used a novel AHPCO or Advanced Hydrated Photocatalytic Oxidation technology to produce filter less air purifier, surface sterilizer for cell phones and meat processing facilities.

 

Methods

We have been analyzing the daily aeroallergen by using the coated Melinex tape from the Burkard Volumetric Spore Trap. Exposed, stained Melinex tape was observed under a BX-40 Olympus microscope. We assessed the AHPCO Technology for potential uses as air purification unit, surface sterilizer and net reduction of bacteria, fungi during food processing. A fiberglass chamber was built to evaluate the performance and safety of the air purifiers. Blood, Human cell culture and plant cells were exposed to the AO chamber and The UV chambers to compare the exposures. Petriplates, meat, vegetables were placed in the chamber to assess the capacity of sterilization. Images were captured with FITC, TRITC Filters with a BX40 and SZ-CTV Olympus Microscopes and SEM.

 

Results

14 years’ aeroallergen data of Texas Panhandle revealed a gradual shift in aeroallergen index with the warmer climate and a shift in flowering seasons.

 

Conclusions

Strong wind current, maximum number of feedlots and dry-land agriculture and a gradual shift in flowering season-- all contribute to a high concentration of allergic cases among the residents of Texas Panhandle. AHPCO technology proved to be an efficient way to reduce aeroallergen and prevent contamination during food processing.
