Figure 1: Influence of greenhouse-gas emissions on stratospheric ozone concentration in northern mid-latitudes. In the 1970s, before chlorine and bromine became the focus of the ozone debate ...

Scientists use data from the Microwave Limb Sounder, MLS, aboard the Aura satellite, which has been making measurements around the globe since mid-2004. Scientists have shown through direct ...

But chlorine and bromine-containing chemicals released by human activity have unbalanced the process, resulting in a loss of ozone that is at its greatest in September/October. The Montreal ...

As such, since early 2000, levels of stratospheric ozone-depleting inorganic chlorine and bromine in the Arctic have declined ...

Repairing the ozone layer demonstrates what is possible ... of both total tropospheric chlorine and total tropospheric bromine from long-lived ODSs have continued to decline since the 2018 Assessment.

Specialized air quality instruments captured a spike in lead, chlorine, and bromine pollution during the L.A. wildfires.

Halocarbons containing bromine usually have much higher ozone-depleting potential (ODP) than those containing chlorine. The man-made chemicals that have provided most of the chlorine and bromine ...

Chlorofluorocarbons, along with other chlorine- and bromine-containing compounds, have been implicated in the accelerated depletion of ozone in the Earth's stratosphere. CFCs were developed in the ...
