Change in the Parameters of Soils Contaminated by Oil and Oil Products

Abstract

The oil well drilling and oil processing industries are globally the main contaminants of environmental condition caused by human economic activities. Oil spills have a negative impact on the environment, economy, and society. In this research, the effects of oil with different chemical contents on soil types formed in two soil-climatic conditions have been studied. The purpose of this research is to study the change of soil properties by oil pollution. The experiments have been conducted in irrigated and non-irrigated soils of the desert region of the Kashkadarya and Surkhandarya (Uzbekistan). The results have shown that aggregates (0.25; 0.5; 1; 2; 3; 5; 7; 10 mm) which are the important of soil fertility have changed by oil and oil production, and the changes have proven to be temporary. The effect of the 5% and 15% concentrations of oil, engine oil, petrol, kerosene has been studied. The aggregates 0.25 mm and 0.5 mm have the biggest change among aggregates, in fact, aggregates of 0.25 mm at the level of 5% of oil decreased by 27.02%, at the level of 15% of oil decreased by 99.8%, at the level of 5% of kerosene decreased by 2%, at the level of 15% of oil decreased by 98.1%. Aggregates of 0.5 mm at the level of 5% of oil decreased by 6.44%, at the level of 15% of oil decreased by 67.14%, at the level of 5% of kerosene decreased by 12.75%, at the level of 15% of oil decreased by 92.8%. Engine oil and Petrol at levels 5 and 15 have relatively rare changed. Also, as a result of oil and oil pollution, the total carbon dioxide in the soil has grown briefly, which is an anthropogenic carbon and insignificant for soil fertility and humus. As a result, an anthropogenic carbon increased in gray-brown soil (Durisols Technic, WRB) at 0 – 35 cm layer by 0.22%, irrigated meadow-alluvial soil (Fluvisols, WRB) by 0.31%, irrigated gray-brown soil (Durisols Technic, WRB) by 0.44%, irrigated Takyr-meadow soil (Calsisols, WRB) by 0.25%, Takyr soil (Calsisols, WRB) by 0.32%, sandy Desert soil (Durisols Technic, WRB) by 0.21%.

Solidification/Stabilization of Contaminated Soil in a South Station of the Khurmala Oil Field in Kurdistan Region, Iraq

“…It is clear that oil disposal caused the contamination of the soil at the Khurmala oil field. The research conducted by Ergozhin et al [47], Kuany et al [48], Wang et al [49], Trejos-Delgado et al [50], and Jabbarov et al [51] confirms the obtained results. All pH values were in the normal range, except the pH value for the soil sample treated with OPC, which is classified in the high alkaline range (pH = 12.74).…”

“…Chemical tests for the clean, contaminated, and tread soil samples are shown in Table 7. It is clear that the values of pH, alkalinity, bicarbonate, sulfate, total orga matter, and oil and grease in the polluted samples were higher than for the clean samp It is clear that oil disposal caused the contamination of the soil at the Khurmala oil fie The research conducted by Ergozhin et al [47], Kuany et al [48], Wang et al [49], T jos-Delgado et al [50], and Jabbarov et al [51] confirms the obtained results. All pH v ues were in the normal range, except the pH value for the soil sample treated with OP which is classified in the high alkaline range (pH = 12.74).…”

Applicability of Ash Wastes for Reducing Trace Element Content in Zea mays L. Grown in Eco-Diesel Contaminated Soil

“…The uptake of available trace elements by plants tends to correlate positively with their content in the soil. Petroleum products have been shown to increase Cd, Pb, Cu, and Mn content in the soil [ 59 , 60 ] and reduce soil pH [ 16 , 61 , 62 , 63 ]. This, in turn, may increase the phytoavailability of trace elements, their uptake biodynamics, and their translocation to aerial plant organs [ 64 , 65 ].…”

Chemical properties and ecological condition changes of the degraded soils as a result of industrial activities

“…The decrease in fertility as a result of man made degradation of soils occurs as a result of damage to the amount and activity of microorganisms contained in it, deterioration in chemical and physical properties, which leads to a decrease in crop yields. [12][13][14][15].…”
