KIEV, March 26 - The appearance of yellow spots on the left bank of the Dnipro River in Kiev is caused by a high content of iron, manganese and humic substances, which subsequently formed yellow and brown ice - slush, the State Environmental Inspectorate.

"The emergence of yellow spots on the Dnipto can be explained by a high content of iron and manganese, as well as humic substances, which in sub-zero temperatures led to the formation of yellow ice in the form of slush. This is a seasonal phenomenon that occurs during flooding and is caused by natural factors," the Inspectorate said.

Inspectorate experts also noted that iron, manganese and humic substances fall into the Dnipro through its tributaries, especially the Prypiat and Desna rivers.
