Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Several factors influence the ability of a metal to produce toxic effects on the body; these include the solubility of the metal the ability of the metal to bind to biological sites and the degree to which the metal complexes formed are sequestered or metabolized and excreted A toxic effect is defined as an undesirable or adverse health effect James et al

·In most mining areas the endpoint production of Cr is probably the most significant source of Cr in the air III is a vital element and has positive effects on humans and plays a significant role in maintaining and lowering the blood sugar level Pechova and Pavlata 2007; Cabral Pinto et al 2017 Cr III also plays a decisive role in
·Coal mining plays a critical role in the economy of South Africa though posing detrimental environmental effects on aquatic life and the terrestrial environments with one of the major impacts
·The sulfur in coal oxidizes upon combustion and pollutes the air water and land by releasing SOx SO 2 SO 3 SO 3 2− and H 2 SO 4 The formation of the poisonous SO 2 gas a major pollutant in air may accelerate the rate of diseases and decrease life expectancy around power plants Bascom et al 1996 Kelsall et al 1997 Health effects of outdoor air pollution
Volcanism and Earth Systems As already noted in Chapter 1 and Chapter 3 volcanic eruptions contribute to the Earth s systems in important starters it is widely believed that the water in the Earth s oceans is at least partly derived from volcanism and the Earth would not have much in the way of systems without water
·These heavy metals are found naturally on the Earth s crust since the Earth s formation Due to the astounding increase of the use of heavy metals it has resulted in an imminent surge of metallic substances in both the terrestrial environment and the aquatic environment [4] Heavy metal pollution has emerged due to anthropogenic activity which is the
