Benefits of Participating

There may be some personal benefits to you from participating in the study. You will have a completely free examination for some medical conditions that can be serious. If you were found to have unrecognized eye, lung, or nervous system problems, or possible diabetes, we would give you two options: Either we would give you a letter describing the problem that you could give to your doctor or optometrist, or, with your permission, we could pass the information directly to your doctor or optometrist.

Quite apart from the benefits to yourself, you will have the satisfaction of knowing that you are participating in a unique study that will contribute new knowledge. This may have benefits for the people of Rotorua and, potentially, people and communities throughout the world. The study will either confirm the adequacy of current permissible exposure limits for H2S, or it will provide evidence that they need to be changed.
