Study of the salt composition of some rivers of the Lerik district

The article is devoted to the study of the ionic and salt composition of the rivers of the Lerik District of the southern part of Azerbaijan. The results of analyzes of the river waters selected as the object of the study show that there were no serious processes of mineralization in the rivers. The salinity of the river waters of the Lerik District (the Bilna River, river waters taken from the villages of Mastail, Lankaranchay, Konjavuchay) varied within the range of 0,440-0.674 g/l. The composition of ions in these water sources varied depending on the rivers.
