THE FIRST DIRECT atmospheric measurements of iodine oxide and bromine oxide above the Antarctic snowpack unexpectedly indicate that the chemicals participate in destroying ozone and change the ...
SOME MARINE organisms have a knack for making steroidal compounds containing halogens. Chemists have long tried to do the same thing, because such compounds can be useful, for example, in treating ...
The cycling of halogen compounds in the lower atmosphere is poorly understood. It is known that halogens such as chlorine, bromine and iodine are converted from halides, which are relatively inert, to ...
Halogens are known to decrease the levels of stratospheric ozone. The latest measurements show that something similar occurs in the lower atmosphere over tropical oceans — and probably above most ...
Organohalogens like perchloroethene and trichloroethene are prominent groundwater pollutants due to their industrial use as dry cleaning and degreasing agents and their widespread release into the ...
Halogens, specifically chlorine and bromine, are suspected of posing serious dangers to human health and the environment when used as a brominated flame retardant (BFR) or in polyvinyl chloride (PVC).
