CFCs are used in refrigeration, air conditioning, insulation (Styro foam), the electronic industry, food industry and were used in aerosol cans until 1985, he said. Freon is a CFG. Levels of CFCs in the strato sphere, where the ozone layer is lo cated, are measured by finding the amount of atomic chlorine present. Mount said. Atomic chlorine results from the breakdown of CFCs in the strato sphere, Mount said, and is the “real culprit.” This reactive chlorine can ‘ 'attack and destroy” ozone, he said. “The amount of atomic chlorine now in the atmosphere over Antarc tica is 500 to 1,000 times higher than normal,” he said, ‘‘and levels in the North are rising.” Ozone levels have decreased more than 60 percent between 1978 and 1987 as a result of increasing atmos pheric atomic chlorine levels, he said.
