In about a week we will contact you to tell you which current
studies are appropriate for you and you may choose whether
to participate in any of them. On the phone, we'll tell
you about the purpose and procedure for any study you choose,
when you'll need to come in for the study, and how you'll
be paid. Speaking of compensation, subjects are generally
paid in stages throughout the duration of the study, beginning
with completion of the training session. The amount of total
compensation varies, based largely on the time commitment
required of you, and the medical tests associated with the
study you elect to participate in.

When
you choose to participate in a particular study, you'll
be scheduled to come in for more thorough orientation and
for training. During this visit, you'll go through a consent
process designed to insure that you are well informed and
comfortable about the study you are participating in.

Many
people have questions about the safety of human studies.
And we'd like to take a moment now to address this concern.
The safety of study participants is the EPA number one priority.
Each study we conduct has been thoroughly reviewed for safety
by EPA scientists, physicians and laboratory personnel,
as well as the University of North Carolina Committee on
the Protection of the Rights of Human Subjects. Before you
begin any study, any potential risks will be explained to
you and given to you in writing.

Many
different kinds of studies are conducted by the EPA. Some
involve simple blood donations. Others involve breathing
common air pollutions like fine particles or ozone, sometimes
while performing activities like walking on a treadmill,
pedaling an exercise bike or taking a dexterity test. In
general, however, your exposure to pollutants will be at
levels no greater than many people are exposed to during
their daily lives.
