The main pollutants contaminating soil are organic compounds (oil and its products, fats etc.), metals, household waste. Comparing to oil and its products, household waste and fats are contaminating soil not so heavily. Additionally, these pollutants are released mostly from domestic sewage, which are usually purified. Soil is contaminated with oil when various oil products (fuel, mineral oils and greases, kerosine) get into it. This happens in cases of various accidents, incidents, railway tanks rolling off the ways, defects in containers with oil products. Oil products spilled in cases of accidents make the heaviest damage to the environment. Growing requirements to environment risk prevention are forcing to have and use sorbents. There shall be their supplies in potential places oj pollution with oil products In order to evaluate sufficiency of their amount, detailed investigation of oil-product sorption is required. Additionally, sorbents shall meet environmental requirements: easily collected, residual sorbents have no harmful impact to nature, biodegradable, with prospective disposal possibilities.
