Hello,

Thanks a lot for for your interest.
These courses have to be carried out at the end of August or in September, and not this year. This is organized in different countries, not only in Spain. In the next year there should be again a course, linked to a COST action (proposal submitted, let's hope we are succesful). If you want to see reference photos, for the moment, you can check at www.ozoneinjury.org. We can also help you to identify ozone symptoms if you send us (me) some photos too.

Best wishes,

Vicent
