New Clues To Ozone Depletion — ScienceDaily

The team of atmospheric chemists carried out an 18-month study of the make-up of the lowest part of the earth’s atmosphere on the Brunt Ice Shelf, about 20 km from the Weddell Sea.

There is more to the snowflake than its ability to delight schoolchildren and snarl traffic. The structure of the frosty flakes also fascinate ice chemists like Purdue University’s Travis Knepp, a doctoral candidate in analytical chemistry who studies the basics of snowflake structure to gain more insight into the dynamics of ground-level, or “tropospheric,” ozone depletion in the Arctic.

What are the causes and effects of ozone depletion? | Socratic

Ozone depletion is primarily caused by human activities. The main effect of ozone depletion is an increase in UV-B rays reaching the earth’s surface.. Causes: chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer.These chemicals are found in cleaning agents, aerosols, insulating foam, and refrigerants.

Addressing Ozone Layer Depletion | US EPA

Addressing Ozone Layer Depletion . Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased skin cancers and cataracts and potential damage to some marine organisms, plants, and plastics.
