ABSTRACT

Industry, pollute environments (air, water, soil), and bring damage to the health, both to the people and all living beings. In areas where oil and gas development is prevalent, air, water and soil resources can become contaminated with oil and gas wastes and by products. The pollutants emitted by the oil and gas industry, may bring damage immediate or long-term, to the environment. Mining industry and the oil processing, affects the environment through gaseous and liquid hydrocarbons. All products resulting from extraction and processing industry of the crude oil are flammable and have varying degrees of toxicity. The paper presents a study of the pollution of the soil, from an area of extraction of the oil. It was determined the pH of the soil, soil humidity and chemical elements. Soil pH was measured in water (1:2.5, w:w). To determine the humidity was used "alcohol burning method". Determination of the chemical elements from soil was carried out using XRF Environmental Analyzer, Innov-X Delta Soil Mode. The acidity of the soil below 7 leads to the destruction of humus, the decrease in the hydrogen concentration and increasing its content of iron, aluminum and other silicates. In the soil there must be a balance between the hydrogen ions and the aluminum to ensure fertility.
