Proposed Project Exposure to Aerosolized Brevetoxins during Red Tide Events (OMB No. 0920-0494)—Revision—National Center for Environmental Health (NCEH), Centers for Disease Control and Prevention (CDC.) Background and Brief Description *Karenia brevis*
                     (formerly 
                    *Gymnodinium breve*) is the marine dinoflagellate responsible for extensive blooms (called Florida red tides) that forms in the Gulf of Mexico. 
                    *K. brevis*
                     produces potent toxins, called brevetoxins, which have been responsible for killing millions of fish and other marine organisms. The biochemical activity of brevetoxins is not completely understood and there is still little information regarding human health effects from environmental exposures, such as inhaling brevetoxin that has been aerosolized and swept onto the coast by offshore winds. The National Center for Environmental Health (NCEH), Centers for Disease Control and Prevention (CDC) has recruited people who work along the coast of Florida and who are periodically occupationally exposed to aerosolized red tide toxins. NCEH administered a baseline respiratory health survey and conducted pre- and post-shift pulmonary function tests (PFTs) during a time when there is no red tide reported near the area. When a red tide developed, NCEH administered a symptom survey and conducted PFTs. NCEH compared symptoms reported before the shift with symptoms reported after the shift. NCEH also examined changes in PFT test results (post-shift values compared to pre-shift values). NCEH did these comparisons during a time when there was no red tide and during a time when 
                    ( print page 52663)
                    there was a red tide and then examined the data to see if red tide exposure had an effect on symptom reports or PFT results. NCEH requests a revision of data collection procedures for the currently approved project and an additional three year extension. Unfortunately, the exposures experienced by the study cohort have been minimal, and NCEH plans to conduct another study (using the same symptom surveys and PFTs) during a more severe red tide event. First, NCEH wants to quantify the levels of cytokines in nasal exudates to assess whether they can be used to verify exposure and to demonstrate a biological effect (i.e., allergic response) following inhalation of aerosolized brevetoxins. NCEH will collect nasal exudates at the same time the PFTs are done. NCEH plans to include the study subjects who have been involved in the earlier studies and any new individuals (n=25) who have been hired to work at the relevant beaches. There is no cost to respondents other than their time. Estimated Annualized Burden Hours
