Question

Quizplus · Accepted Answer

Chlorofluorocarbons (CFCs) are man-made chemicals often found in refrigerators, air conditioners, and aerosols, which release chlorine and bromine into the atmosphere. These chemicals react with ozone molecules and break them down, contributing to the depletion of the ozone layer. Fluorine is a highly reactive gas and is not a significant contributor to ozone depletion. PCBs (polychlorinated biphenyls) have been banned since the 1970s and are known for their harmful effects on the environment, but they do not contribute to ozone depletion. Ethanol is a renewable fuel source and does not have an impact on ozone depletion.
