The risk of the chlorine byproducts (total trihalomethanes)
Total trihalomethanes 1974 by the U.S. Labath Dr. Harris (Harris report) mentioned substances, and thus instant fame. The domestic test tap water a few years ago a total trihalomethanes.
The report mentioned that the organic matter contained in the tap water - chlorine chemical reaction and produce cancer-causing substances - total trihalomethanes, drink chlorine-treated water, compared with people drinking groundwater drink chlorine even those treated water per 100,000 people in

Thirty-three cancer deaths, far more than the proportion of people who drink groundwater, this is a shocking fact. <br>
Water pollution (organic matter) and the of organochlorine compounds generate the list goes on, and chlorine can combine with organic matter. Total trihalomethanes, chlorine kind of dead leaves and other organic compounds formed by the decomposition of plant rot substantia nigra produce a chemical change, it will form a total

Trihalomethanes.
Each water contains organic compounds are trace amounts, and can not be clearly determination, which accounted for 20 percent of total trihalomethanes. Carcinogens not just total trihalomethanes. Some even say that there are twenty kinds, in fact there are even more behind in total trihalomethanes

Multi-carcinogens.
The original water pollution is more serious, the more the amount of chlorine input. In addition, according to statistics from the seriously polluted rivers in the sampling tap water, the amount of total trihalomethanes detected. In other words, total trihalomethanes water pollution indicators, but if in the future

More serious water pollution, the amount of total trihalomethanes occurrence.
In recent years, people cause of death has always been the first in cancer. And metropolitan cancer mortality is higher. The most serious water pollution problems metropolis, seem to have a correlation between cancer mortality and water pollution, to Members how does that feel?
