Clinical exams and medical testing will be comprehensive. The Study involves the use of metabolomics, an approach that allows for the identification of thousands of chemicals and metabolites in participants’ blood, encompassing various pollutants that may remain in the body for many years. We will also examine health status, lung function, hematologic (i.e., blood) impact, and inflammation markers. In addition, data from the disaster period and a symptoms survey will be incorporated to address the lack of published medical data on chemical exposure effects.
