Anthropogenic air pollutants, such as soot and other particulate matter, have been shown to possess a host of health concerns including respiratory diseases or cardiovascular dysfunctions. However, the exact implications of soot exposure remain understudied in the avian lung. Here, we aim to uncover the temporal effects of soot on the gene expression of an experimentally exposed captive Australian zebra finch population, using transcriptomic data sourced from lung tissue. The temporal effect is measured by comparing treatment groups at two timepoints: Immediately after exposure and after two months. By better understanding how soot exposure affects birds over time and from a mechanistic perspective (i.e., by focusing on the molecular responses post-exposure), we will be better equipped to monitor potential risks to their health in the urban environment.
