Soil contains most oxygen (about 50%) and silicon (about 25%), other elements are mainly aluminum (clay), iron, calcium (limestone, gypsum), sodium, potassium, magnesium, hydrogen, titanium, in lesser amounts carbon, chlorine, phosphorus, sulfur and manganese. Health effects of selected heavy metals. In the area of groundwater quality in the Slovak Republic, the issue of adverse oxidation–reduction conditions is at the forefront, which is often indicated by increased concentrations of iron (Fe), manganese (Mn), and NH4. In natural waters, potassium, iron, manganese and small amounts of other metals are represented in small concentrations, by which the water is enriched in contact with the soil, with various minerals and rocks. It is often created on warm sunny days at rush hours. The effects of sudden metal uptake into organisms may have the character of “acute disease”. Human exposure occurs through all environmental media. Decomposers feed on finished organic substances. When a soil is contaminated with heavy metals it is difficult to be remediated. Biological pollutants are described as pollutants which exist as a result of humanity’s actions and impact on the quality of aquatic and terrestrial environment. It is usually found in the form of cadmium sulfide (CdS) in ores which also contain lead (Pb), zinc (Zn) and copper (Cu). According to the UN, about 783 million Earth inhabitants does not have access to drinking water and about 2.5 billion people do not know sanitation systems, while the quality of water resources is worse. All of these rivers are primarily important as water source not only limited to supplying water to consumer but also for other purposes such as aquaculture and agriculture activity, fishing, effluent discharge, irrigation and even sand mining. The most common metals include: Rainwater with a pH value of 5.0–5.6 is slightly acidic because carbon dioxide is found in the air and absorbed by the air humidity. Our readership spans scientists, professors, researchers, librarians, and students, as well as business professionals. This includes microorganisms, plants and animals. Ozone is a gas that is poisonous at higher concentrations. In the environment, they can occur as simple complexes with inorganic ligands (in the aqueous environment, the form of the metal is affected by physico-chemical properties: pH, temperature, ionic strength), as chelates with organic ligands (sorbed to solid surfaces), free metals. Anthropogenic processes of heavy metals have been noted to go beyond the natural fluxes for some metals. The soil contains both autotrophic and heterotrophic bacteria. In terms of air pollution, NO2 photolysis, which can initiate photochemical smog, is of paramount importance. Therefore it is important to create favorable living conditions also for livestock (active health creation) based on the fundamental phenomena - complexity of measures and respect for the variability of the effects of relationships and factors between the internal and external environment [7]. Located between 80 and 600 km in the mesosphere and thermosphere, it consists of neutral gas, ions and electrons. Producers are the bases of aerobic life on the Earth and their photosynthesis is significantly utilized in self-purification of water. The composition and properties of air: Air is an essential component of the biosphere, without which the existence of various forms of life on Earth would not have been possible. Pollution of surface waters – the so-called “Eutrophication” is a set of natural and man-made processes leading to an increase in inorganic nutrients in water, especially nitrogen and phosphorus compounds, followed by increased growth of cyanobacteria, algae and higher plant forms, resulting in worsened ecological stability and reduced water quality.
