What is a THM and what is an example compound?
Trihalomethanes (THMs) are used in industry as solvents or refrigerants. THMs are environmental pollutants, and many of them are considered carcinogenic. Trihalomethanes with all the same halogen atoms are called haloform, and they are considered to be volatile organics. Some examples of trihalomethanes are: Chloroform.
What are the four THMs?
The 4 compounds that make up trihalomethanes are: chloroform, bromodichloromethane, dibromochloromethane, and bromoform.
What are examples of trihalomethanes?
Trihalomethane
- Chloroform.
- Bromoform.
- Chloramine Derivative.
- Ozone.
- Bromodichloromethane.
- Dibromochloromethane.
- Bromine.
- Chlorine.
Is chloroform a THM?
The trihalomethanes are chloroform, bromodichloromethane, dibromochloromethane, and bromoform. EPA has published the Stage 1 Disinfectants and Disinfection Byproducts Rule to regulate total trihalomethanes (TTHM) at a maximum allowable annual average level of 80 parts per billion.
What are trihalomethanes?
Trihalomethanes (THMs) are chemical compounds in which three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Many trihalomethanes find uses in industry as solvents or refrigerants.
What happens when tryptophan reacts with trihalo compounds?
Specifically, tryptophan reacts with certain trihalo compounds to produce a tryptophan adduct that emits fluorescence. The rate at which the chemical reaction produces fluorescence is enhanced with the addition of the trihalo compound compared to the rate with UV activation alone.
What are trihalomethanes and chloroform?
Trihalomethanes were the subject of the first drinking water regulations issued after passage of the U.S. Safe Drinking Water Act in 1974. This section needs expansion. You can help by adding to it. (March 2021) Only chloroform has significant applications of the haloforms.
Is the covalent binding of the trihalo compound sufficient for protein detection?
However, the covalent binding of the trihalo compound is enough to provide high sensitivity protein detection.
