The goal of our study is to establish an elemental database that includes statistical correlations for trends and sources of elemental contaminants found in house dust within Indiana homes. Through the measurement of the elemental content of house dust, we aim to identify specific elements of concern, such as lead and fluorine (which serves as an indicator for PFAS).
In addition to analyzing the elemental data, we will utilize a statistical analysis technique called Positive Matrix Factorization (PMF) to explore the relationships between different elements as well as the collected metadata. This will enable us to identify potential sources of these elements and gain deeper insights into their origins.
We are excited to share regular updates as we continue to receive, measure, and analyze more of your dust samples. Stay tuned for the latest findings!
