Soil micropollutants after using methods supporting the bioremediation process

The purpose of this study is to evaluate the potential of Effective Microorganisms and vegetation as methods to support soil bioremediation processes. The research included, conducting an experiment in which organic matter in the form of digestate, compost, slurry, sewage sludge and a selected soil remediation method were introduced into the soil. Application rates were 40 m 3 /ha of digestate, 20 Mg/ha of compost, 40 m 3 /ha of slurry and 9 Mg/ha of dry matter of sewage sludge. The content of polycyclic aromatic hydrocarbons was analyzed after the application of remediation support methods. Monitoring changes in the content of PAHs in the soil after the application of remediation methods was crucial for evaluating the effectiveness of these processes. Such studies allowed optimization of remediation processes depending on the specific contaminants and soil conditions. The use of integrated soil remediation methods enabled effective action on multiple biological and chemical fronts, leading to improved soil quality and environmental protection. The use of the EM method in combination with vegetation and the addition of sewage sludge to the soil allowed for a reduction of the sum of 16 PAHs in the soil by 68.1 % compared to the control without the aided methods, which confirms the high effectiveness of the aided soil remediation methods in the degradation of polycyclic aromatic hydrocarbons.
