Aerosols from cyanobacterial blooms: exposures and health effects in highly exposed populations

Eligibility Screening Survey

Hello, I’m ___________________. I’m working with the Centers for Disease Control and Prevention and the Florida Department of Health. I’d like to know if you are willing to help us with a research study about cyanobacteria, also known as blue-green algae.

You may have heard about cyanobacteria, also called blue-green algae. They are very tiny organisms that grow in water. Some types of cyanobacteria make chemicals, called cyanobacterial toxins. We know these chemicals can cause liver or kidney damage in people when they drink water with a lot of cyanobacterial toxins in it. We don’t know what happens if people are exposed to these chemicals in the air.

The purpose of our study is to find out 1). If the toxins made by these blue-green algae get into the air and then into people’s bodies and, if so, 2) if exposure to these toxins affects people’s health. Similar studies have been done in Florida, Michigan, and California.

We are looking for people who spend at least 2 hours outside each day and who live or work on or near Lake Okeechobee and connecting rivers to be in our study.

CDC estimates the average public reporting burden for this collection of information as 15 minutes per response, including the time for reviewing instructions, searching existing data/information sources, gathering and maintaining the data/information needed, and completing and reviewing the collection of information. An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to CDC/ATSDR Information Collection Review Office, 1600 Clifton Road NE, MS D-74, Atlanta, Georgia 30333; ATTN: PRA (0920-xxxx).

We are asking you for your verbal consent to answer our screening survey questions. We will ask you for your signed consent before you do any study activities. Do you give us your verbal consent to ask the screening questions?

<IF YES> Thank you for your interest in this study.

<IF NO> Thank you for your interest in this study. But we will not be able to proceed with the screening survey without your consent. Thank you again.

Now, I have a few questions about you:

Age (yrs)	Sex	With which racial group do you most closely identify?	Are you of Hispanic origin?
___Years  Don’t know  Refused	 F  M  Other  Don’t know  Refused	 1. American Indian/Alaska Native  2. Asian  3. Black or African American  4. Native Hawaiian/other Pacific Islander  5. White  6. Don’t know  7. Refused	 Yes  No  Don’t know  Refused

Now, I have a few more questions about whether or not you are eligible for our study.

Are you able to understand English, Spanish, or Haitian Creole?

<IF YES> OK, great.

<IF NO> Thank you for your interest in this study. But we are looking for people who can understand at least one of those languages.

Do you spend at least 2 hours a day outdoors each day for work or other activities?

<IF YES> OK, great.

<IF NO> Thank you for your interest in this study. But we are looking for people who spend at least 2 hours each day outdoors.

Are you able to complete a lung function test? The test involved blowing hard into a tube for as long as you can. We need you to do this at least 3 times each session.

<IF YES> OK, great.

<IF NO> Thank you for your interest in this study. But we are looking for people who are able to do a lung function test.

If you agree to participate, we will ask you to do the following before the bloom season and during the bloom season (approximately March through November):

• Read and sign a consent form

• Make 5 appointments with study staff to do study activities (study days 1, 2, 3, 4, 5). These are not consecutive days, but will be near the time the bloom starts, during the bloom and at the end of the bloom (approximately March through November)

• On study days 1, 3, and 5:

  • Provide a blood specimen for liver enzyme levels and creatinine levels in the morning

  • Receive training on how to collect a urine sample

  • Do the following in the morning and evening:

    • Complete symptom survey

    • Provide urine specimen for cyanobacterial toxin levels

    • Perform lung function test

    • Provide nasal swab for cyanobacterial toxin levels

  • Wear a personal air sampler for the day

  • Record time spent outdoors using our form

  • Allow study staff to put an air sampler for aerosols and an air sampler for gases and vapors (e.g., hydrogen sulfide) near the canal you live on

  • At the end of the day, allow study staff to collect air monitoring equipment

• On study days 2 and 4:

  • Do all study activities you do on study days 1, 3, and 5, except that you will not need to give us a blood sample.

We expect these activities to take about 15 hours of your time altogether.

Will you help us with our study?

IF NO:

Okay, well, thank you for your time.

IF YES:

Thank you.

First, I will ask you some questions to see if you qualify to be in our study.

Then I’ll ask you to read and sign a consent form and answer a few more questions.

IF PERSON IS INTERESTED IN BEING IN THE STUDY

Okay, just to be sure, you are typically outdoors for at least 2 hours each day, correct?

IF THEY SAY “NO” to any of these questions:

Thanks. But we can only include people who will be outdoors for at least 2 hours each day.

IF THEY SAY “YES” to all three questions:

Thanks. You are eligible to be in our study.

May I please have your name, home address or workplace address, e-mail address, and phone number(s) so we can contact you with study reminders? Once the study is complete and we no longer need to contact you, we will remove your name, address, email address, and phone number(s) from our records and they will not be kept as any part of this research study.

Baseline Survey for those interested and eligible to be respondents

NOTE

• The questions about exposure to cyanobacteria and algae-containing supplements are based in the need to assess sources of exposure to cyanobacterial toxins

• The questions about asthma, COPD, emphysema, chronic bronchitis, and the household and living environment are from the previously OMB-approved Behavioral Risk Factor Surveillance Survey (BRFSS) Asthma Call-back Survey –2007 Adult Questionnaire and the Baseline Questionnaire for the Green Housing Study (question 16a).

• The questions about liver disease, bowel disease, and alcohol consumption are based on published findings of the possible affects from exposure to cyanobacterial toxins.

• The questions about smoking, height, and weight are needed to interpret the lung function tests.

Now, I have a few more questions about you and your lifestyle that can help us interpret the information we collect from you.

What do you do that may have exposed you to cyanobacteria during your activities?

 Collect water samples

 Collect cyanobacteria samples

 Other
