Reducing Total Petroleum Hydrocarbon from Soil Polluted with Iraqi Crude Oil by Phytoremediation Technology

Abstract

Abstract- They used anew-green technology phytoremediation to reduceand remove pollutants from the soil. The purpose of the current researchstudy was to survey the effect of soil pollution with a variety of doses ofcrude oil on the generation and growth of the plants. The study was madefor 120 days from March to June in a control condition in the greenhouseand laboratory. Unpolluted soil near the Tigris River was taken and bepolluted with varied doses of crude oil. They used alfalfa, Cotton and Grassin this research to reduce pollution. It made a comparison between theresults of the three plants species to choose the best plant for totalpetroleum hydrocarbons removal from the soil. Grass plant gave thegreatest result in total petroleum hydrocarbons removal, which gave up to50.66% for Treatment 4, and cotton came in second place with 49.82%removal rate in treatment 2. Alfalfa came at the end with a removal rate of31.78% for treatment 2 of the crude oil.
