15 +This page gives an indication of the pollution groups present in the modern regulations of the SIKB and a description of every group. Soil pollution as part of land degradation is caused by the presence of human-made chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons, solvents, pesticides, lead, and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapors from the contaminants, or from secondary contamination of water supplies within and underlying the soil.[1]

17 +The defined pollution groups are the following: phenols, heavy metals, oil, PAK's, radiation, fibres, volatile hydrocarbons, volatile chloridehydrocarbons and germs.

21 -== Sub-paragraph ==
21 +In organic chemistry, phenols, sometimes phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (—OH) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, C,,6,,H,,5,,OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Chemical structure of salicylic acid, the active metabolite of aspirin. Phenols are both synthesized industrially and produced by plants and microorganisms.

25 -=== Sub-sub paragraph ===
25 +Chromium, Mercury, Arsenic, Lead, Nickel, Cadmium, Copper, Zinc, Manganese, Selenium, Silver, Tin, Thallium Cobalt and Vanadium are the heavy metals that can be present in the subsurface. These heavy metals are very dangerous for the environment and most of them can be transported via the groundwater. The amount of these metals in the subsoil shouldn't transcend the local geochemical baseline concentrations. (GBCs)

27 +Heavy metals can degrade air, water, and soil quality, and subsequently cause health issues in plants, animals, and people, when they become concentrated as a result of industrial activities. Common sources of heavy metals in this context include mining and industrial wastes; vehicle emissions; lead-acid batteries; fertilizers; paints; and treated timber; aging water supply infrastructure; and microplastics floating in the world's oceans.

43 +Mineral oil is in general oil that is made from petroleum in contrary to oil with an animal- or plant-based origin. For the production of different types of mineral oil, petroleum is distilled and produces fractions consisting of different mixtures of hydrocarbons with different boiling points. As a rule a distinction is made between the following fractions:

54 +Polycyclic aromatic hydrocarbons (PAHs) are substances created when organic materials such as wood, food, tobacco and fossil fuels are not burned completely. There are hundreds of different PAHs, with different properties. Plants can absorb some PAHs from the soil; thus, through food crops, they can end up in our bodies. Other PAHs are not absorbed by plants, and enter the body only when soil particles are eaten
55 +
56 +All the different types of PAHs need to be considered differently and they have different exceedance values. PAHs are found in the ambient air in gas-phase and as sorbet to aerosols. Atmospheric partitioning of PAH compounds between the particulate and the gaseous phases strongly influences their fate and transport in the atmosphere and the way they enter into the human body. The removal of PAHs from the atmosphere by dry and wet deposition processes are strongly influenced by their gas/particle partitioning. Atmospheric deposition is a major source for PAHs in soil. [3]
