Exposure Measurements during Activities Conducted on

Synthetic Turf Fields with Tire Crumb Rubber Infill

CONSENT TO PARTICIPATE IN A RESEARCH STUDY

Overview

The Agency for Toxic Substances and Disease Registry (ATSDR) invites you, as an adult aged 18 or older (or the legal age in your state), to be in a research study about personal exposures either from synthetic turf fields or from natural grass fields. Your participation is voluntary. We invite you to read or hear about the study. Before you decide to take part, please ask questions if there is anything that you do not understand.

What is the purpose of this study?

The purpose is to see how people might be exposed to chemicals in crumb rubber infill in synthetic turf. Crumb rubber is the black material used as cushioning in synthetic turf fields. The crumb rubber is most often made from recycled tires. For comparison, we will also be recruiting some people who play on natural grass fields. We want to ask some questions about your activities on synthetic turf fields or natural grass fields. We will also collect urine samples from you. This information will help us see if people might be exposed to chemicals from playing on synthetic turf fields. We will use the results of this study to guide public health actions.

Why are you being asked to be in this study?

You were chosen to take part in this study because you work out on synthetic turf fields or on natural grass fields. We want to talk to people like you who take part in recreation, training, or organized sports on these fields.

ATSDR hopes to enroll at least 200 people to answer some questions and to provide urine samples so we can look what chemicals you are exposed to while playing on the field. In total, participants will spend about 50 minutes in this research study.

Public reporting burden of this collection of information is estimated to average 5 minutes per response for total participation, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data 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 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 Reports Clearance Officer; 1600 Clifton Road, MS D-74, Atlanta, GA 30333, ATTN: PRA (0923-XXXX).

What are we asking you to do?

We will ask you a few questions about yourself in an interview. We will ask questions about your activities on synthetic turf or natural grass fields. We want to know about the types of your activities, how often you play on the fields, and how long you have been playing on the fields.
You will be asked to provide 50-100 ml (about ½ cup) of urine in a cup both before your practice and after your practice. You will do this in private in a restroom.

We will not be collecting any personal information (e.g. names, address, etc.), and you will not receive a copy of your test results.

How long will this take?

It will take about 30 minutes to complete the interview. It will take about ten minutes to collect each of the urine samples.

Are there any risks or discomforts to you if you decide to be in this study?

We don’t think these questions are sensitive. But the interview may be stressful if you have to recall events that are upsetting. You are free to skip any question for any reason. There are no medical risks from providing urine.

Are there any benefits to you from being in this study?

There will be no direct benefits to you from being in this study.

Who will see the information you give the researchers?

All information that you provide will be secure. We will track your information using a study ID number. We do not plan to link your study ID number with your identity. We will keep paper records in locked files. Electronic records will be stored on password protected computers at ATSDR. Only trained study staff will be allowed to look at your records. Federal policy requires making the data we collect available to the public.

What will happen to my urine samples?

Your urine samples will be shipped to and stored at the Centers for Disease Control and Prevention (CDC) laboratory in Atlanta, GA.

Your urine samples will be analyzed to look for some chemicals that might be found in crumb rubber infill or in the natural grass field. Afterwards, the samples will be stored for the indefinite future. This is in case we get more information in the future about what chemicals to look for or in the case that new methods are developed to test for chemicals found in crumb rubber infill.

We will not analyze these samples for DNA, drugs, tobacco, or health conditions.

Your potential future urine results may be linked to the questionnaire data that you are asked to provide. Your samples will be labeled with a study ID number only and will not be shared with researchers outside of CDC/ATSDR.

What is the cost to you and what compensation will you get?

The only cost for being in our study is your time and effort to take part. We will give you a $25 gift card as a “thank you” when you complete the interview. You can use the gift card at most stores or for online shopping.

People who also provide urine samples will get additional gift cards ($10 pre-activity and $15 post-activity).

What are your choices about participating?

Your participation in this study is voluntary. You are free to be a part of it or not. You can refuse to give a urine sample. You can choose to leave at any time prior to final sample collection even after you have agreed to participate in the study.

Who should you contact if you have questions later on?

We are doing a study to learn about how people use playing fields with crumb rubber and to see how people might be exposed to chemicals in crumb rubber infill in synthetic turf. Crumb rubber is the black stuff that makes the fields soft to play on. It is usually made from recycled tires. We also want to learn if people are exposed to chemicals from the crumb rubber. We are asking adolescents, 13 to 17 years of age, to participate in this study. For comparison, we will also be recruiting some people who play on natural grass fields. You were selected to take part in this study because you play on synthetic turf with crumb rubber or on natural grass fields.

If you agree to be in our study, we are going to ask you some questions about how you play or practice on the fields. For example, we want to know how often you fall or slide on the ground.

You can ask questions about this study at any time. It should take about 30 minutes to finish the interview. If you decide at any time not to finish, you can ask us to stop.

The questions we will ask are about how you play or practice on the fields. There are not right or wrong answers because this is not a test.

We will collect two urine samples, one before you begin your activity on the field and one after you finish your activity on the field. We will ask you to collect your urine in a cup we will give you. It should take you 10 minutes for each sample to do this.

Other Information

There are no risks from giving urine.

Your mom/dad has said it is ok for you to be in the study but it is up to you if you want to take part. You can decide whether or not to take part in this study. You can ask questions about this study at any time. If you decide at any time not to finish, you can ask us to stop.
