Trichlorofluoromethane in Florida
Trichlorofluoromethane (Freon 11) is a refrigerant, solvent, chemical intermediate and halocarbon aerosol that was banned in 2000 under the Montreal Protocol because of its ozone-depleting properties. [read more]
Trichlorofluoromethane is a chemical that had been used as a refrigerant, solvent, chemical intermediate and in the making of fire extinguishers. It was banned in 2000 under the Montreal Protocol because of its ozone-depleting properties (NJ Department of Health and Senior Services 1998c).
Trichlorofluoromethane is extremely cardiotoxic in monkeys, and also decreases respiration in dogs. Repeated exposure can cause irritation of the skin (Gosselin 1984).
Environmental releases of trichlorofluoromethane are primarily associated with chemical manufacturing facilities (U.S. Environmental Protection Agency (USEPA) 2009i).

Health Based Limits for Trichlorofluoromethane
|California Public Health Goals||Defined by the State of California Office of Environmental Health Hazard Assessment (OEHHA) as the level of contaminant that is allowed in drinking water. For acutely toxic substances, levels are set at which scientific evidence indicates that no known or anticipated adverse effects on health will occur, plus an adequate margin-of safety. PHGs for carcinogens or other substances which can cause chronic disease shall be based solely on health effects without regard to cost impacts and shall be set at levels which OEHHA has determined do not pose any significant risk to health.||700 ppb|
|Lifetime health-based limit, non-cancer risk||Concentration of a chemical in drinking water that is not expected to cause any adverse, noncarcinogenic health effects for a lifetime of exposure. The Lifetime health-based limit (or Health Advisory, HA) is based on exposure for a a 70-kg adult consuming 2 liters of water per day. Source: U.S. Environmental Protection Agency.||2000 ppb|
|Health-Based Screening Level||A benchmark concentration of contaminants in water that may be of potential concern for human health, if exceeded. For noncarcinogens, the HBSL represents the contaminant concentration in drinking water that is not expected to cause any adverse effects over a lifetime of exposure. For carcinogens, the HBSL range represents the contaminant concentration in drinking water that corresponds to an excess estimated lifetime cancer risk of 1 chance in 1 million to 1 chance in 10 thousand. Source: U.S. Geological Survey.||2000 ppb|
|Children's health-based limit for 1-day exposure||Concentration of a chemical in drinking water that is not expected to cause any adverse, noncarcinogenic health effects for up to one day of exposure. The One-Day health-based limit (or Health Advisory, HA) is typically set to protect a 10-kg child consuming 1 liter of water per day. Source: U.S. Environmental Protection Agency.||7000 ppb|
|Children's health-based limit for 10-day exposure||Concentration of a chemical in drinking water that is not expected to cause any adverse, noncarcinogenic effects for up to ten days of exposure. The Ten-Day health-based limit (or Health Advisory, HA) is typically set to protect a 10-kg child consuming 1 liter of water per day. Source: U.S. Environmental Protection Agency.||7000 ppb|
|Drinking Water Equivalent Level||A lifetime exposure concentration protective of adverse, noncarcinogenic health effects, that assumes all of the exposure to a contaminant is from drinking water. Source: U.S. Environmental Protection Agency.||10000 ppb|
