Chlorinated hydrocarbons are organic compounds that contain carbon, hydrogen, and chlorine atoms. They are often used in industrial applications, such as solvents, pesticides, and refrigerants. Due to their chemical structure, these compounds can be stable and resistant to degradation, which can lead to environmental concerns. Many chlorinated hydrocarbons, like dichlorodifluoromethane (commonly known as Freon), have been linked to ozone depletion and other ecological issues. Some of these compounds can also be harmful to human health, potentially causing respiratory problems or other adverse effects upon exposure.
