Chlorine drinking water at common levels in the United States and the European Union may increase the risk of many cancer, a New analysis From modern research from all over the world.
The water cleansing process with three -methane chlorine, which is a secondary product found in all public drinking water systems throughout the United States and the European Union – creates approximately 300 million people in the United States who have levels in their waters, by one by one appreciation.
While chlorine is a “cheap, effective and easily available” method to kill living organisms and infectious diseases, it comes with the barters, including an increased risk of bladder cancer by 33 % and an increase of 15 % of the risk of colon and rectal cancer.
“What we see is worrisome and we need some high -quality studies,” said Emily Hillti, a leader at the Carolinska Institute in Sweden.
The water cleansing process is a basic measure of public health significantly increases the average life expectancy when the United States began to break the drinking water in the early twentieth century because it greatly reduced microbial infections and diseases transmitted by water, such as cholera and typhoid fever.
Until the seventies of the last century, the researchers discovered that the operation came with consequences. When chlorine is added to the water, it interacts with organic compounds, such as decomposing plant materials, to create any hundreds of toxic secondary products.
It is known that some of the most common – chloroform, bromoporm, bromoicoro methane and chlorine methane – of genetic toxicity and cancer of mice.
The United States and the European Union have placed restrictions on secondary products at 80 parts per billion (PPB) and 100PB, respectively, but new research indicates an increase in cancer risk of low levels of up to 40pb, which was found in New York City. Environmental Protection Agency reports are usually in a range of 40 to 60PB and non -profit environmental work levels to defend public health Estimates Safe level at 0.15PB.
The new Meta study is among the most confirmary evidence that it looked at data from about 30 studies and 90,000 participants, and found that men were more likely to be at risk than women. The authors only looked at the effect of the bladder and colon and rectal effects because there is a scarcity of searching for other cancers. Hitti said that researchers are not sure why chemicals were targeted by the major intestine and bladder.
The problem creates a difficult tension for the organizers. Surface water usually has a higher level of groundwater because it contains more organisms and organic materials for antiseptics to interact with them. water Hiltty said that some organic materials outside the water can be cleaned before disinfection, and it is also possible to reduce the amount of chlorine added, but “it is really important not to use a little antiseptic.”
Hiltty said alternatives such as water treatment with UV light or installation of new filtration systems as well, but expensive.
She stressed that people should continue to drink municipal water. The granular activated carbon is among the best filtration systems that can be used at home to remove pollutants.
