A new investigation out of Johns Hopkins University has discovered that ordinary drinking water in the US — the kind people get straight from the tap — may contain unintended and highly toxic compounds that outcome from the technique used to disinfect water. The issue rotates around chlorine, which is the most mainstream technique for purifying drinking water in the US; however this has helped spare a large number of lives from fatal water-borne diseases, it comes with an unforeseen result.
Water-borne diseases are, obviously, things like typhoid and dysentery that can be contracted from drinking contaminated water. These diseases might be deadly, especially in kids and the older; dirty drinking water is liable for a huge number of deaths consistently. Chlorine is a well-known technique for treating drinking water as it adequately executes off pathogens.
As per another investigation led by Johns Hopkins University and recently published in Environmental Sciences & Technology, utilizing chlorine to treat drinking water likewise produces ‘highly toxic byproducts’ within the sight of chemical compounds called phenols. Since phenols are extremely normal in things like medication and hygiene products, they’re likewise regular in water.
Phenols and chlorine produce ‘a large number of byproducts’ the point at which they mix, as indicated by the new examination. The analysts behind this project set out to recognize these resulting compounds, a procedure that included chlorinating water a similar way that drinking water is dealt with and afterward adding a compound fundamentally the same as the lysine amino acid found in the human body. In the wake of letting the mixture incubate for a day, the group utilized mass spectrometry to break down the chemicals.
This procedure prompted the revelation of two BDA compounds in the water, the two of which are portrayed as ‘very toxic’ and known carcinogens. This was the first time BDA compounds were found in chlorinated water, bringing up issues over the effect this technique has on human health and whether different strategies like filtration would be increasingly prudent.
