Talk:Critical level

Critical level redirect removed
Good day. I removed the redirect on this page to Exosphere. The concept of critical level is widely used and important in the study of pollution (eg air pollution). It refers to the concentration in the atmosphere above which direct adverse effects on receptors such as plants, ecosystems or materials may occur according to present knowledge. As such, it is not appropriate to redirect to Exosphere. At best I would support a disambiguation page as opposed to a redirect. I welcome your thoughts.
