Overall, the effects of UVB radiation on organisms, the environment, and materials are expected to decrease as stratospheric ozone recovers; however, the potential effect of climate change on these endpoints is uncertain and it is possible that increases in temperature may combine in additive, ...
The production of old CFC refrigerants, such as R12, has now been banned due to its effect on the ozone layer. It has an ozone depletion factor (ODF) of 1. The use of R12 for maintenance has been banned from 1 January 2001.

Human activity has damaged this protective layer of the stratosphere, but scientists say the ozone layer is on track for recovery.
refrigerants with an estimated ODP value of zero and without any chlorine, called “HFCs.” Some examples of HFCs mentioned above are R-125, R-134a, R-143a, and R-152a. Research and development activities have particularly focused on the use of these ozone- and environment-friendly ...
The ozone treatment had a positive effect on the survival of the eggs (z = 2.962, p = 0.003 and z = 2.352, p = 0.019, for 1- and 5-day exposed plants respectively, Fig.3A,B). The survival was also positively affected by the number of eggs laid per plant (z...
The ban came into effect in 1989 and since then it has had positive effects on the environment. Ozone levels stabilized9 by the mid-1990s and began to recover in the 2000s. Recovery is projected to continue over the next century, and the ozone hole is expected to reach pre-1980 levels ...
