Water chlorination can increase our risk of certain cancer

An important tool for keeping our drinking water purity can be more risky than we think. The new research finds a connection between water chlorination and increase in certain cancers.

Scientists of the Karolinska Institute of Sweden have led the research, which is examined by former research facing chlorination and cancer. The highest level of people exposed to the highest level of chlorine was more to develop polls and colorectal cancer than the lowest levels. This relevant risk begins at low levels of security in the United States and Europe, is not enough to protect the public in the current rules.

Been chlorine regularly used To disinfect drinking and recreational water since the early 20th century. Helped to eliminate or reduce the spread of dangerous diseases such as tifoid fever and cholera. However, it is known that there are shortcomings of chlorine and other disinfectics. In a large disadvantage, these chemicals mixed with organic compounds in crude water and are created by these chemicals mixed with the most prominent side products of chlorine, the establishment of a disinfectant substance. Past research At least rodents can cause cancer, but in chlorinated water showed whether the work is more confused in people.

Previously previously studied research limited evidence a link between Thms and bladder and colorectal cancers. However, these reviews have been more than a decade and have more new, more potentially informative research for the topic published since then. Thus, Karolinska scientists tried to carry out the updated meta analysis of the investigation.

In the end, they analyzed the information from 29 documents, for the last year. Although most of the research looks at bladder and colorectal cancer, a total of 14 cancers were assessed. Researchers could not find an important link between the Th ‘exposure and the two other cancers. However, the highest THM level (in the lowest rate) was 15% higher than the risk of bladder cancer and higher risk of colorectal cancer. The important thing, starting from 41 parts (PPBs) in the United States, this additional risk, 80 ppb regulations in the United States and 100 PPB in the EU.

“In this systematic view and dose response meta-analysis, the limited proposal that increases the risk of bladder cancer and colorectal cancer, which is exposed to drinking water in drinking water,” they wrote in researchers. published This is in January Environmental health prospects.

There are also other technologies that can disinfect the fine water of the indication, such as ultraviolet lighting. Experiments such as water cleaning organic matter can lower the THM levels before being treated with chlorine. However, researchers are not enough to prove a result and effect link between chlorinating and cancer of information gathered so far. Also based on the people and findings, they will not tell the society to go cold to drink drinking crane water. At the same time, it is urgently calling for better research to look at and confirm this possible risk.

“What we see is concerned and we need higher quality research,” the leading researcher Emilie Helte Guardian.
