Impact/Purpose:

The number and intensity of hurricanes is increasing because of climate change. Environmental Justice (EJ) communities frequently are the most vulnerable to flooding. In collaboration with researchers at the University of Puerto Rico, we studied the impact of Hurricane Maria on the EJ community of Piñones, Puerto Rico. We showed that homes made of wood were most likely to suffer longer term mold damage. Therefore, the use of wood construction should be avoided to prevent long term health effects from mold exposures associated with flooding. Governments and health care organizations should be interested in applying these results.

In order to quantify the impact of the hurricane on the indoor air quality, we evaluated the fungal levels in households (n = 20) of the Piñones community for the period of 2018 and 2019. For each dust sample collected, the 36 Environmental Relative Moldiness Index (ERMI) molds were quantified using qPCR assays, and then Shannon Diversity Index (SDI) values for the fungal populations were calculated. Homes were in five separate regions, regarding their proximity in the studied area. We found that for regions with reported least water damage, the SDI values were similar for both sampled years, but for regions that reported mid-to-high level of damage region, the SDI values were significantly higher. Households that reported remediation actions between the two sampled years showed similar values for the second year as those that did not report any major impact. Our preliminary data provides insights into the significant impacts of hurricanes into indoor fungal environment.
