Pollution is being removed more slowly from the atmosphere in the northern hemisphere than previously assumed. An international research team that includes researchers from Wageningen University established that the atmospheric cleaning agent hydroxyl (OH) is found in the same concentrations in the southern and the northern hemisphere. Until now, scientists had assumed that there would be more OH in the atmosphere in the more polluted northern hemisphere as the cleaning agent is produced where there is pollution.
