Iraqi soil contamination greatly influenced soil detachment. Previous researchers have not been able to predict the influence of crude oil soil contamination on either the mechanistic dimensional detachment parameter b0 or the threshold parameter b1 of the mechanistic detachment model (Wilson model). The aims of this research were (1) to investigate the influence of crude oil on deriving Wilson model parameters, b0 and b1, with two setups at different scales and different soil moisture contents and (2) to predict b0 and b1 in crude oil contaminated dry soils with varying levels of contamination. The “mini” JET apparatus was implemented under laboratory conditions for soil specimens packed at both a small (standard mold) and a large (in-situ soil box) scale. The results showed an inverse correlation between b0 and water content for clean soil. No correlation between b0 and soil moisture content was observed for contaminated soils. There was a huge reduction in the b0 value as the contamination time increased compared to the clean soil. This was related to the role crude oil plays in soil stabilization. Crude oil contamination significantly increased lead contamination level while slightly increasing the pH and total organic carbon. The influence of crude oil on mechanistic soil detachment can be predicted with a priori JET experiments on soils without crude oil based on crude oil parameters.

Bioremediation technologies are an environmentally friendly approach for the treatment of polluted soils. This review take a look at the various remediation efforts by various scientist to ameliorate the effect of crude oil contamination on the environment. Contamination of the total environment (air, soil, water and biota) by crude oil has become a paramount interest in the Niger Delta region of Nigeria. With the frequent reports of oil spillages in the Niger Delta area, there is need to seek for a cost effective method for remediation of crude oil impacted soils. Studies have revealed variable impacts of oil toxicity on the environment and exposed populations. Soil contamination is caused mainly by the leakage of underground storage tanks and pipes. The most common conventional method for the remediation of contaminated soils is excavation followed by landfilling or incineration and other technologies that have been widely practiced. Contaminated sites pose a threat to human life due to severe health problems caused by adverse health effects from exposure to soil contamination. Once it is being detected, assessment strategies, type of sampling, chemical analyses, evaluation of parameters and its effect must be done. Several technologies and parameters have been developed to treat petroleum hydrocarbon contaminated soil but the problem still exists.

The industry of the Republic of North Ossetia – Alania is represented by metallurgy, Metalworking, fuel, electric power, woodworking and forestry, and has the production of building materials. Industrial dust and aerosols and vehicle emissions are important sources of soil contamination with metals. The degree of soil contamination with metals may present a hidden risk to human health, taking into account the routes of entry (by oral administration, by skin contact, and by inhalation). The purpose of this work was to study environmentally-related pathology and develop preventive measures aimed at its prevention. To achieve this goal, we used epidemiological and sanitary - statistical research methods based on data from official documents and reports containing information about the state of health of the population of the Republic of North Ossetia – Alania. The article presents the results of epidemiological and sanitary-statistical methods for studying the sanitary and chemical indicators of the soil of the Republic of North Ossetia – Alania, and their impact on the health of the population. When assessing the environmental situation of the territory of the Republic of North Ossetia – Alania, special attention is paid to the study of such sanitary and chemical indicators as lead, cadmium, zinc and copper, which are priority polluting microelements. For the city In Vladikavkaz 2017-2019, the proportion of samples taken for cadmium exceeded the MPC in 76.0 - 79.2% of cases, for lead - 88.0 – 90.5%, and for zinc-68.0 - 80.0 %. There is an increase in environmentally-related pathology, which is probably due to unfavorable environmental conditions for lead, cadmium, and zinc.

The Impact

Soil defilement with "raw petroleum" is a standout amongst the most across the board and genuine ecological issues going up against both the industrialized and oil country like Iraq. Along these lines, the impact of "raw petroleum" on soil contamination is one of most critical subjects that review these days. The present examination expects to research "unrefined oil"effectson the mechanical and physical properties of clayey soils. The dirt examples were acquired from Al-Doura area in Baghdad city and arranged by the "Brought together Soil Grouping Framework (USCS)" as silty mud of low pliancy (CL). Research center tests were done on contaminated and unpolluted soil tests with same thickness. The dirtied tests are set up by blending the dirts with various percent of "raw petroleum", and these percent are5%, 10% and 15% by dry weight. The exploration results demonstrate a reduction in the quality of the dirt, explicit gravity, greatest dry thickness and ideal dampness content. Then again, the outcomes showed an expansion in Atterberg cutoff points and compressibility of the dirt. The outcomes demonstrated additionally an impressive increment in the estimation of combination parameters such ascoefficient of volume compressibility, pressure file and lessening in the coefficient of solidification and shear quality.
