Pool-pumpkin with arsenic in Grand Canyon

In the depths of the Grand Canyon in Arizona the Colorado River flows wonderful. Many people floated on her boat, but in a beautiful nature there is what really does no one expects to see - a huge pumpkin! When fused on the river, it is a miracle to 342 km.





Pool protrudes from the slope of the canyon and overhanging the river, and the name of this unusual formation Pumpkin Spring, or Pumpkin Creek







For thousands of years tykvopodobny pool expanded to the size that you can now safely be described with the help of quotations from the books of Roald Dahl (Charlie and the Chocolate Factory). But though the creek and looks tempting, it is not as harmless as it may seem.




Pumpkin creek - it travertine, limestone deposits of carbon dioxide sources. As you can see, it takes the deposition of eccentric shape, and often looks as if it were a vegetable. Because of this vessel into the river gets caustic liquid, but it is necessary to be afraid of what is in himself.




I must say that the water in the pumpkin looks good warm, but it can not be called safe. It is peppered with high levels of arsenic, copper, zinc and lead. Many people can not resist the temptation to jump there, but in this case, then you need a very good rinse under running water. Drink this water is strictly prohibited.



This is probably the most dangerous waters in the Grand Canyon. Compare the established norm of arsenic in the water must be not more than 50 milligrams per 1 liter. Recent studies of water in Pumpkin Creek found in 1 liter of water 1 100 milligrams of arsenic!



Arsenic poisoning is not pleasant. It all starts with a headache, disorientation, indigestion and sleepiness. If not urgently address to the doctor, then begin vomiting, hematuria, convulsions, hair loss, stomach pain, leading to coma and then death. Of course, a quick dip in the water stream will not cause any danger to life, however, as they say, better safe than nedobdet.
