Act (44 U.S.C. Chapter 35). To request a copy of these requests, call
the CDC Reports Clearance Officer at (404) 639-5960 or send an e-mail
to omb@cdc.gov. Send written comments to CDC Desk Officer, Office of
Management and Budget, Washington, DC or by fax to (202) 395-6974.
Written comments should be received within 30 days of this notice.

Proposed Project
Exposure to Aerosolized Brevetoxins during Red Tide Events (OMB No.
0920-0494)--Reinstatement with change--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 form 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 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 reinstatement with change of data collection
procedures for the previously approved project for an additional three
years. The respondents for this reinstatement with change are a
recruited group of approximately 25 lifeguards (aged >=18) who work
along the coast of Florida and who periodically are occupationally
exposed to aerosolized red tide toxins. The lifeguards and employees of
the Department of Environmental Protection, (Sarasota County), Florida
were recruited via a posted notice requesting volunteers. NCEH plans to
re-contact study participants previously enrolled and add additional
lifeguards hired previously to work at the relevant beaches.
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. We propose to add a component to this study to
assess whether loratidine, an antihistamine available in over-the-
counter products, such as Claritin, can relieve the upper respiratory
symptoms induced by inhaling aerosolized brevetoxins during Florida red
tides.
There is no cost to respondents other than their time. The total
estimated annual burden hours are 16.
