Influence of Western Keivy Massif Rocks on the Chemical Composition of Natural Waters (Kola Peninsula, Russia)

The presented work is a logical continuation of the study of the chemical composition of the Lovozero district waters (the Kola Peninsula, Russia), an area inhabited by indigenous populations. The problem was posed due to the discovery of rare earth elements in drinking water in the Lovozero district (the Krasnoshchelye village). For monitoring, inductively coupled plasma was used, and the “water–rock” interaction was studied using “Selector” software. The results showed the Western Keivy Massif influence on the chemical composition of natural waters, which are used for drinking purposes for humans and animals. The interaction of water with magmatic rocks such as gabbro and subalkaline granites also leads to the formation of some major cations, anions, and heavy metals. Li, Sr, Y, La, and Ce concentrations are higher than in the Central’niy water intake located within the Khibiny Massif. The results of the modeling demonstrate the high migration capabilities of rare earth elements. The presence of rare elements and REEs in drinking surface and groundwaters, if consumed on a regular basis, can cause diseases of the nervous system and other organs.
