The U.S. Environmental Protection Agency manages the "Toxic Release Inventory" (commonly known as TRI) which was created to provide the public with information about releases of toxic chemicals in their community. It is an essential tool for finding information on chemicals by city, zip code, state, and year. TRI tracks Hydrogen Fluoride, Sulfuryl Fluoride, Fluorine, and other fluoride compounds.
The Toxic Release Inventory (TRI) list of 24 compounds below contains 16 hydrochlorofluorocarbons (HCFCs), 7 chlorofluorocarbons (CFCs) and 1 halide. All these compounds on the TRI list have ozone depleting potentials. Combined they release millions of pounds of fluoride each year into the environment. Enviropedia gives this definition for HCFCs with the caveat that many of those listed below are included in the Montreal Protocol on Substances that Deplete the Ozone Layer:
Hydrochlorofluorocarbons, commonly known as HCFCs, are a group of man-made compounds containing hydrogen, chlorine, fluorine and carbon. They are not found anywhere in nature. HCFC production began to take off after countries agreed to phase out the use of CFCs in the 1980s, which were found to be destroying the ozone layer. Like CFCs, HCFCs are used for refrigeration, aerosol propellants, foam manufacture and air conditioning. Unlike the CFCs however, most HCFCs are broken down in the lowest part of the atmosphere, and pose a much smaller risk to the ozone layer [not the ones on the list below]. Unfortunately HCFCs are also very potent greenhouse gases, despite their very low atmospheric concentrations, measured in parts per trillion (million million).
The following data comes from the Environmental Protection Agency’s TRI. These releases pollute our bodies, air, water, soil, and wildlife. It’s important to emphasize, especially at the community level, that not all industries or sources that release fluoride into the environment are included in the TRI.

Freon 113 (Trichlorotrifluoroethane)CAS No. 76-13-1 Added to TRI’s original list in 1988 Molecular formula: C2-Cl3-F3 This ozone depleting substance belongs to this Group of the Montreal Protocol which states: “stop consumption or production of chemicals on Group 1 of Annex A after January 1, 1996.” Health Effects: Suspected Neurotoxicant, Cardiovascular or Blood Toxicant, Respiratory Toxicant. Uses: It has been used as a cooling agent in refrigerants and air conditioners, aerosol propellant, and a cleansing agent for electrical and electronic components. CFC-113 is one of the three most popular CFCs, along with CFC-11 and CFC-12 and saw much use in its time. CFC-113 is a refrigerant used in cooling systems. CFC-113 also is a very volatile and apolar molecule so it was used as a foaming agent in the production of packaging material, insulation, foams for cushioning, and things like shoe soles. CFC-113 has such a low flammability and low toxicity that it was also used as a cleaner for delicate electrical equipment, fabrics, and even metals Many Other Names: CFC 113, 1,1,2-Trichloro-1,2,2-trifluoroethane, Trichlorotrifluoroethane |

Health Effects. The following TRI substances, listed below, have been identified as suspected neurotoxicants:
There are 8 Ozone Depleters in the TRI, listed below, that are being used in the U.S. in contravention of the Montreal Protocol, which the U.S. ratified in 1988. The Montreal Protocol states that the following ozone depleters should not be used or produced:
The reasons why the U.S. is not in compliance may be due to their requests for Critical Use Exemptions as this 1992 definition explains in the Montreal Protocol:
Use of a controlled substance should qualify as essential only if:
Very little information on health effects is available. Up to 1991 very little was known about the metabolism and toxicity of hydrochlorofluorocarbons (Anders, 1991). A 1995 study reported inorganic fluoride metabolites in HCFC-131a, HCFC-132b, HCFC-133a (Yin et al, 1995); Dekant et al. reported HCFC-123a metabolized to inorganic fluoride; increased fluoride was found in the urine of rats exposed to HCFC-124 (Brashear et al, 1992); also WHO, 1992.
