Trace and Toxic Elements in the Soils of Different Ecosystems of Plateau Areas of the South Urals

Abstract

The study of chemical elements, including toxic ones, is the primary task of modern soil science in conditions of increasing anthropogenic impact on the environment. For various reasons, natural environments are overloaded with compounds of heavy metals, and some of them constitute a very dangerous group of substances. Therefore, it is important to quantify these flows and study their potential impact on natural ecosystems [1,2]. Typically, 14 elements are considered: mercury, lead, cadmium, arsenic, antimony, tin, zinc, aluminum, beryllium, iron, copper, barium, chromium, thallium. Heavy metals include more than 40 metals of the periodic system of Mendeleev with an atomic mass of more than 50 atomic units: V
