Maui County firefighters concerned within the reaction to the 2023 Maui wildfires had upper median summed concentrations of a few perfluoroalkyl and polyfluoroalkyl elements (PFAS) than different responders, consistent with analysis printed within the Feb. 6 factor of the U.S. Facilities for Illness Regulate and Prevention Morbidity and Mortality Weekly File.
Catherine C. Beaucham, Ph.D., from the CDC in Atlanta, and associates describe first responders’ exposures to PFAS after responding to wildfires in Maui, Hawaii, in August 2023, measured about one month after preliminary reaction. Particular person serum PFAS concentrations had been in comparison to the Nationwide Well being and Diet Exam Survey (NHANES) ninety fifth percentile concentrations for individuals elderly two decades and older.
The sum of 7 PFAS used to be in comparison to the Nationwide Academies of Sciences, Engineering, and Drugs (NASEM) medical threshold, above which screening for most cancers and different opposed well being results must be prioritized. Blood samples had been submitted by way of 258 Maui County workers, together with 178 firefighters.
The researchers seen vital variations within the concentrations of perfluorohexane sulfonic acid (PFHxS) by way of occupational subgroup, with the perfect concentrations observed amongst firefighters. The perfect detected PFHxS focus in a firefighter used to be 9.3 µg/L, which used to be about 2.5 occasions the NHANES ninety fifth percentile (3.8 µg/L).
General, 2 to 40 % of Maui County workers, together with firefighters, had been over the NHANES ninety fifth percentile for the opposite PFAS chemical compounds. The median sum serum concentrations of 7 PFAS used to be 7.0 µg/L amongst firefighters; all workers bar one firefighter had concentrations under the NASEM medical threshold of 20 µg/L. For different occupational subgroups, the median sum serum concentrations of 7 PFAS ranged from 5.7 µg/L to six.9 µg/L.
“To protect first responders during disasters, it is essential to continue providing strategies for characterizing and reducing exposures,” the authors write.
