A master's thesis in the Department of Ecology at the College of Science at the University of Basra discussed The ability of fungi loaded on compost produced locally by three species of the genus Aspergillus to treat oil-contaminated soils.

The researcher Nemat Abdel Karim Mohsen's thesis showed the role of fungi loaded on organic fertilizer in treating oil-contaminated soil as an environmentally friendly means of getting rid of organic pollutants.

The study aimed to combine recycling organic waste and bioremediation of oil-contaminated soil

The study recommended paying attention to environmental safety conditions, not throwing away oil waste without treating it, and recycling organic waste in a safe and environmentally friendly manner.
