Bromine and iodine emitted by the oceans contribute to ozone layer destruction

SIC Notícias13 September 2026 at 09:00

The oceans emit bromine and iodine that contribute to ozone layer destruction. During the peak period of anthropogenic ozone layer destruction, between 1990 and 2020, natural halogens played a significant role in this process. These natural chemical elements were responsible for approximately 15% of the total halogen-induced ozone loss throughout the stratosphere. This data highlights the importance of considering not only anthropogenic sources of ozone-depleting substances, but also natural contributions to the problem.

Why this matters

This research is relevant for readers in Portugal and Europe because it demonstrates that ozone layer destruction is not only the result of human activity, but also of natural processes that need to be better understood. Ozone loss directly affects UV radiation exposure, with implications for public health, ecosystems and agriculture in the region.

Can sitting in the same place always say something about your personality? Find out

The recurring choice of the same seat to sit — with family, at work, or among friends — can reveal psychological needs such as the search for familiarity, control, and territoriality. The occupied position can also reflect the person's social role in the group: sitting at the head of the table suggests greater central participation, while the sides allow for observation and less exposure. However, experts warn that the preference may have practical explanations, such as comfort, lighting, or proximity to someone, and is not sufficient to define personality.
