Planet Earth's water is in danger due to climate change

Weather of Arabia - A recent study conducted by the University of Miami warned of the danger of climate change on the waters of lakes and rivers on Earth, as it found an increase in organic runoff or brown water coloration, which may limit the penetration of ultraviolet (UV) rays, and thus cause water poisoning planet.

This may lead to a significant increase in the number of waterborne pathogens, which will result in the infection of 19 million people each year with various diseases .

Researchers at the University located in Ohio conducted an analysis of water samples, and measured the increase in brown water pollution in the world, a phenomenon resulting from the washing of more organic matter into the surrounding land, according to the Daily Mail.

And the lead researcher in the study and environmental scientist at the University of Miami, Craig Williamson, explained that the increase in dissolved organic matter impedes the work of the sun by purifying the water, and also makes it difficult for water treatment plants to work effectively .

As researcher Kevin Rose of Rensselaer explains, the amount of clear water is declining in many areas due to several factors, such as browning the water, which reduces the natural cleansing of potentially harmful pathogens.

The research team adopted samples from lake waters around the world, from Pennsylvania and Wisconsin, to Chile and New Zealand, and the tests determined the amount of dissolved organic matter in each sample, and the wavelengths of light, including ultraviolet waves, that that organic matter absorbed, and it made it possible The results let the scientists measure the effects of dissolved organic matter .
