The Ozone Layer Treaty's Unforeseen Consequences.
A study by scientists from the University of Saskatchewan has found that human activity is releasing significantly more of the organic solvent bromoform (CHBr3) than previously assumed. Produced by phytoplankton and algae, the compound was never considered for regulation by the Montreal Protocol. However, it is also a byproduct of chlorine's sterilization of water, expanding the range of sources we humans do have some control over. The increase in anthropogenic sources of the chemical could bump up its global levels by as much as nearly a third compared to previous estimates, which could affect the ozone layer.
