The soil was clayey clay with mild alkalinity and acidity, according to the results of the physical and chemical investigation. The findings revealed the impact of crude oil on various soil parameters, including low pH and high total nitrogen, moisture content, organic matter, EC, and the total carbon to total nitrogen ratio. Plant phenotypic and biochemical measurements, such as chlorophyll measurement, were also included in the study. In addition, sixteen polycyclic aromatic hydrocarbons (PAHs) were identified. The pollutants recognized by the US Environmental Protection Agency included naphthalene, acenaphthylene, acenaphthene, fluorine, phenanthrene, anthracene, fluoranthene, pyrene, benz[a]anthracene, chrysine, and benzene [b] in plants by extraction and chromatography utilizing HPLC analysis technique. The results show that majority of these chemicals accumulate in Cassia glauca, including: benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[g,h,i]perylene, and indeno[1,2,3cd-pyrene]. After a month of testing, in the plant, demonstrating the plant's efficacy in eliminating polyaromatic hydrocarbons (PAH).
