The parties to the Montreal Protocol are informed by three panels of experts. One of these is the Environmental Effects Assessment Panel (EEAP), which deals with UV radiation and its effects on human health, animals, plants, biogeochemistry, air quality and materials. Since 2000, the analyses and interpretation of these effects have included interactions between UV radiation and global climate change.

The Environmental Effects Assessment Panel is one of the three expert panels within the Montreal Protocol. This EEAP deals with the increase of the UV irradiance on the Earth's surface and its effects on human health, animals, plants, biogeochemistry, air quality and materials.

A further area of highly interesting research emphasizes the importance of indirect UV radiation effects on plants, pathogens, herbivores, soil microbes and ecosystem processes below the surface. Although photosynthesis of higher plants and mosses is seldom affected by enhanced or reduced UV-B radiation in most field studies, effects on growth and morphology (form) of higher plants and mosses are often manifested.

Although some studies have found this technique to be superior to other conventional methods, its use is still not very popular. In this single-blinded prospective study, the intraoperative events and postoperative morbidity after the use of harmonic scalpel in tonsillectomy (HST) was evaluated in 180 cases in two hospitals and compared with conventional steel tonsillectomy (CST) and hemostasis secured by bipolar diathermy or ligatures in 100 cases.
