Environmental studies have consistently shown an association between air pollution and exacerbations of illness in people with respiratory diseases such as Asthma (Zhengmin, 2010). Asthma, a chronic disorder in over 160 million people causing one death every twenty seconds, involves the interaction of airflow obstruction, bronchial hyper-responsiveness, and inflammation (WHO, 2005). Medical practitioners currently attribute any degradation in lung health to pathophysiological factors, and routinely suggest expensive steroids and other inhaler treatments to alleviate respiratory disorders. The goal of my research is to uniquely quantify the effect of airborne pollutants on the degredation in lung health of asthmatic patients enabling targeted remediation that incorporates both pathophysiological and environmental factors.It was hypothesized that the Peak Expiratory Flow (PEF) rate of asthmatic subjects varies inversely with the concentration of each pollutant, including airborne particulate matter (PM10), carbon dioxide (CO2), carbon monoxide (CO) and total volatile organic compounds (TVOCs). In Phase 1, over 100 subjects were recruited to participate in this study. Using scientific and HIPPA compliant methods, over 4 million air quality and PEFR readings. Based on the Pearson R Correlation coefficient, a strong inverse correlation was determined between the degradation in the PEFR and the PM10 and TVOC levels, but not between the CO2 and CO concentration levels.
In Phase 2, I developed a novel mathematical model and an interactive online application to quantify the percent what percent of a subject's PEF degradation is caused by the levels of PM10 and TVOC in each subject's environment. Medical practitioners and Environmental specialists alike could use my mathematical model as it provides a better estimate for the PEF rate and supports targeted remediation of indoor air quality. I have written a letter to the Chairman of the EPA and the U.S. President asking them to allow me to present my findings to them and discuss possible amendment to the Clean Air Act needs to include TVOCs as a criteria pollutant. Possible ideas for future research include engineering a smart thermostat that monitors air quality real-time and studying the effect of TVOC on the endothilial lining of our lungs.
I am excited to learn more about how you have quantified the effect of indoor air pollutants on the peak expiratory flow rate. Looking forward to meeting you at the conference.
ReplyDeleteThere are several approaches for controlling asthma and allergy symptoms. As advocated by the Environmental Protection Agency - improve your IAQ through source control - ventilation - and air cleaning.
ReplyDeleteAsthma suffers should consider purchasing an air filtration/ventilation system with a MERV 12 rated filter that captures outside air pollens and mold spores, ensuring only fresh air is released into the home.
I have one of my Indoor Air Quality business. It control of your indoor air quality by reducing pollutants that can contribute to headache, lung irritation and fatigue as well as more long-term conditions such as asthma, allergies and infectious diseases. I hope you like it.
ReplyDeleteA clean furnace filter is a great way to help people with allergies and asthma live a healthier life by pulling aggravating allergens from the air. Our Our Furnace Filters business is one of the good service provider.
ReplyDeleteMaintaining your air conditioner its degradation rate and allows your equipment to run better and closer to its original condition at a lower cost to you. Our ac service 77006 is one of the best service provider.
ReplyDeleteMost people spend over 90% of their time indoors, not knowing that the air they are breathing may be more polluted than the air outside. Indoor air pollution levels can be 100 times higher than the air outdoors. Our AC Repair ,Humble is one of the best service provider.
ReplyDeleteThis is important information that people need to know. I know that most of the people did not know the effect of indoor air pollution. Furnace Repair West Town
ReplyDeleteAir conditioning units are a great relief. It purifies the indoor air and removes all the contaminants from the indoor air to provide clean and healthy inside temperature. Air Conditioning Repair Lake Clarke Shores
