Chemicals released after Hurricane Harvey may have lasting health effects, according to an ongoing study from Baylor College of Medicine’s Center for Precision Environmental Health. Cheryl Walker, the center’s director, told Houston Matters that the study comes in response to concern in the community. Walker says the study began immediately after Harvey and is now almost complete. It used health questionnaires and personal monitoring devices to help study the long term health effects of the flood, from allergic reactions to mental health. So far, the study has found that what people see in their homes may not be the best predictor of who will be adversely affected. Instead, Walker said that changes in individuals’ microbiomes were better at predicting adverse reactions than people reporting mold in their homes. According to the study, things like stress and diet also may have an effect. Walker emphasized that the study is not yet complete and that they are still studying the specific impacts of these exposures.
