Oil pollution of soils is chemically complex process and it is mostly occurred around of oil drilling fields and pipeline systems. At the same time with oil hydrocarbons such compounds as salts, heavy metals, sulphides and other chemical mixture occur in the soil. The studied soils are long-term polluted. The grey-brown and sandy soils differ from other soils by low supplied chemical, humus, and micronutrients contents as well as their average fertility. The concentrations of As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sb, V and Zn elements in soils were determined by Aqua regia method. Furthermore, the variations in the contents of soil pH, organic carbon and humus contents under oil pollution were studied.

Тупроқларнинг нефть билан ифлосланиши мураккаб кимёвий жараён бўлиб, асосий ҳолларда нефть конлари ва нефть узатиш тизими атрофида кузатилди. Нефть билан ифлосланиш билан бир вақтда тупроққа тузлар, оғир металлар, сульфид ва бошқа моддалар ҳам тушиши аниқланди. Бундай тупроқларни кўп йиллар давомида ўрганиш натижасида аниқландики, сур тусли қўнғир ва қумли чўл тупроқлар бошқа тупроқларга нисбатан озиқа элементлар, микроэлементлар ва гумус билан кам таъминланган ҳамда унумдорлиги паст эканлиги аниқланди. Aqua regia методи асосида As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sb, V и Zn элементларининг концентрацияси аниқланиб, ушбу хоссаларга боғлиқлиги очиб берилди. Бундан ташқари тупроқ рН муҳити, органик углерод ва гумуснинг ифлосланиш билан вариацияси ўрганилди.

Нефтяное загрязнение почв представляет собой химически сложный процесс, и в основном оно происходит вокруг нефтяных буровых месторождений и трубопроводных систем. В то же время с нефтяными углеводородами в почве встречаются такие соединения, как соли, тяжелые металлы, сульфиды и другие химические смеси. Изученные почвы подвержены многолетнему загрязнению. Серо-коричневые и песчаные почвы отличаются от других почв низким содержанием химических веществ, гумуса и микроэлементов, а также их средним плодородием. Концентрации элементов As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sb, V и Zn в почвах определяли методом Aqua regia. Кроме того, были изучены вариации содержания рН почвы, содержания органического углерода и гумуса при загрязнении нефтью.
