The EPA limits the total concentration of the four chief constituents (chloroform, bromoform, bromodichloromethane, and dibromochloromethane), referred to as total trihalomethanes (TTHM), to 80 parts per billion in treated water. [6] Traces of chloroform are produced in swimming pools. [7] [8] [9] [10]

Heptafluoropropane (HFC-227ea) contributes to climate change.It has a global warming potential (GWP) of 3,220 over 100 years. [3]Due to its high GWP, the HFC-227ea has been included in the list of controlled substances of the Montreal Protocol (2016 Kigali amendment, in effect in January 2019). [4]
These toxic chemicals are avoided today in consideration of the fact that there are alternative water based, non-toxic heavy liquids like sodium polytungstate solutions. [1] With this relatively new heavy liquid densities up to 3.1 g·cm −3 can be adjusted . Adding parts of pulverulent tungsten carbide increases the density to 4.6 g·cm −3. [2]
