The Effect of Dust Storm Particles on Human Lung Epithelial Cells

Dust is one of the most common natural atmospheric aerosol particles. During dust storm events there is an increase in particle concentration, many are breathable and can penetrate deep into our lungs. Once in the lung, it can cause our lung cells to over-stress and die, which can manifest in inflammation. Therefore, exposure to dust particles can lead to respiratory complications, particularly for people with asthma. In this project, we are investigating the impacts that dust storm particles from different sources and concentrations (doses) have on human lung cells under different exposure times. These findings will help us to better understand the health-related consequences of exposure to dust storm events and will help us to set new regulations in areas with dust storms. We hope to better understand the implications of dust particles in different geographical locations around the globe.
