Abstract

Indoor Air Quality (IAQ) has become a major concern for the public health. Global warming exerts substantial effect on flora and fauna. Increasing greenhouse gases cause accelerated pollinosis and fungal spore production, two major aeroallergens for asthma and allergies. We used a Burkard Spore Trap for aeroallergen sampling that provided us with the information regarding the onset, duration, and severity of the pollen season that clinicians use to guide allergen selection for skin testing and treatment. We also used pollen grains from different plant species of our locality for identifying and characterizing the pollen through Scanning Electron Microscopy. We examined the samples with an SEM (TM-1000) after gold coating and Critical Point Drying. We measured the pollen grains using the TM-1000-imaging software that revealed the micro-morphology with the size of colpi, sulci and the detailed microstructures. This information can aid data for classification and circumscription in Angiosperm taxonomy. For viewing the fluorescence in pollen, we used 2-3 drops of Fluorescein-based dyes with deionized water on the slides. The slides were mounted and observed under the microscope. During the last two decades, the use of SEM has greatly increased our knowledge of the microstructure of pollen. Mature pollen grains are stable in a vacuum: this allows quick preparation for SEM examination. The low level of technical expenditure required, in combination with the high structural diversity exhibited and the intuitive ability to understand the "three dimensional", often aesthetically appealing micro-structures visualized, has turned pollen studies into a favorite tool of many taxonomists. The daily weather was recorded including temperature, wind speed, precipitation, humidity, average soil temperatures. This allowed the estimation of the clinical significance of the various pollen types by combining data concerning in vivo allergenicity and terminal velocity as a means to judge the clinical significance. Presently our Laboratory has been focusing on the issues of PM2.5 pollution. Particulate matter of 2.5 micron is a major issue in Global Air Pollution. WHO reports that a very high number of people die every year due to this particulate pollution.

Presently our Laboratory has been focusing on the issues of PM2.5 pollution. Particulate matter of 2.5 micron is a major issue in Global Air Pollution. WHO reports that a very high number of people die every year due to this particulate pollution. With is current scenario of air pollution we have targeted in developing an advanced level of air purifier to solve the problem of Indoor Air Quality or IAQ. Global economies are so tightly interconnected that companies, governments and industries will soon be forced to cooperate in ways we could not have imagined just a few years ago. Innovations in technology continue to have massive effects on business and society. We're now seeing emerging markets become hotbeds of innovation, especially in efforts to reach the growing middle class and low- income consumers around the globe.

This technology has been used for building novel filter-less air purifiers, cell phone sanitizers, food preservation equipment and electronic AFL masks for preventing COVID-10 and other airborne diseases.
