Research
Our research with Georgia State University’s School of Public Health (GSU) addresses the human toxicity of aerosols released by E-cigarettes or electronic nicotine delivery systems (ENDS). Initial research data on chemical emissions were released, "VOC Emissions and Exposure from E-cigarettes,” during the 2020 International Society of Exposure Science Annual Meeting in September. More than 70 different VOCs were identified in the emissions. Work is continuing on cellular assays for toxicity measurements.

Research
Our newest research is evaluating the unintentional fire risks of operating DIY air cleaners. Increasing arid climates, extreme temperatures and neglected forest management are leading to more destructive wildfire events, resulting in harmful combustion aerosols entering homes, schools and other enclosed spaces. These aerosols contain harmful chemicals and particulate matter that can affect people’s health. People are now taking steps to remove smoke from their homes, schools and workplaces by using simple and inexpensive DIY air cleaners built with a box fan and a common furnace filter. Working with the The Office of Research and Development at U.S. EPA, we are evaluating fire potentials under different dust loading conditions.

COVID-19 and Facility Management
The respiratory virus SARS-CoV-2, that causes the disease COVID-19, has changed the world and facility managers have adapted to these new circumstances by learning ways to keep commercial tenants and staff healthier and safer. Any process that expels air from the nose or mouth will make aerosol droplets, coughing (about 3,000 droplets) and sneezing (approximately 40,000 droplets) produce the most. Understanding the science of how COVID-19 is transmitted and the importance of good indoor air quality (IAQ), helps mitigate the risk of infection and widespread sickness at schools, workplaces, and residences.
As a facility manager, find out how you can manage indoor air quality in schools and businesses.

Analytical Toxicology Laboratory in Atlanta
Chemical Insights expanded its laboratory in 2020 by adding a second large specialized environmental exposure chamber. Our chambers are designed and operated for realistic use and testing of products or processes so that human exposure risks to environmental pollutants can be measured. Current protocols use internal robotic systems to realistically operate or use products, and online measurement systems to record pollutant levels such as particulate matter (PM) in various size ranges and chemicals. Active research usage includes measuring inhalation, ingestion, and dermal exposure to flame retardants and toxicity indicators.
