trihalomethane

But environmentalists say trihalomethane contamination is merely a symptom of greater problems with the water supply.

And by increasing the level of organic material in the water, they help produce trihalomethane, a chemical that is considered a potential health hazard.

To be sure, chloramines do not produce trihalomethane compounds as chlorine gas does.

Trihalomethane is a byproduct of chlorination used to purify the water supply.

When work is carried out, results are achieved. In Finland, for example, high levels of trihalomethane in drinking water used to be a problem.

It is a trihalomethane.

The colorless, sweet-smelling, dense liquid is a trihalomethane, and is considered somewhat hazardous.

In chemistry, for trihalomethane compounds.

Tests have shown that water in North Haledon contains high levels of a suspected cancer-causing chemical called trihalomethane.

Problems were encountered only in Orense (trihalomethane) and in Girona (pesticides).

Bromodichloromethane is a trihalomethane with formula CHBrCl.

The New Jersey Public Interest Research Group recently started a campaign against trihalomethane contamination, which it said was increasing in the state's water systems.

It is the main trihalomethane produced in salt swimming pools with some public swimming pools found to contain up to 1.3PPM bromoform.

Bromodifluoromethane or Halon 1201 or FC-22B1 is a gaseous trihalomethane or a hydrobromofluorocarbon.

Unfortunately, the breakdown of trihalomethane HCFCs does still result in the creation of some free chlorine radicals in the upper atmosphere and subsequent ozone destruction.

For instance, levels of chloramines with their resulting toxic trihalomethane by product are subject to Federal guidelines even though water management implementing those policy constraints are carried out by local water boards.

In addition, because free chlorine ions and other related chemicals can react with organic substances in water to yield trihalomethane analogues that are suspected of being carcinogenic, their use should be avoided.

Two other substances in bottled water have not been addressed in the regulations: flouride and trihalomethane, or THM, a carcinogen that occurs in water that has been chlorinated.

The Passaic Valley Water Commission, which supplies water to North Haledon, is building a new water plant, which will dramatically reduce the amount of trihalomethane in the town water.

Mr. Tudor acknowledged there was a problem in North Haledon, but he said there was no evidence the amount of trihalomethane was reaching a dangerous level in other parts of the state.

Thus there is clearly greater demand for the control of trihalomethane - I would draw your attention to the fact that there are a number of systems where no such analyses are carried out -, and for the long-term replacement of lead pipes.
