Petroleum Hydrocarbons in Water, Soil and Tomato Plant (Lycopersican esculentum L.) at Basra City, Iraq
Abstract
This study focused on the determination of Total Petroleum Hydrocarbons (TPH) concentration in soil, water and tomato plant Lycopersican esculentum L. at ( root , stem, and leaf ) and biomass of these plant in four stations Safwan , shuaiba , Abu Al-kasibe and Garma Ali at Basra city, Iraq. The result show that higher concentrations of (TPH) in the soil and water of Safwan than other stations related to industrial , agricultural and domestic activities which released to environment contaminated to the ground water. The result also show variation in ( TPH ) between Lycopersican esculentum parts ( root , stem and leaf ) , the higher concentration was found in tomato root of Safwan station compare to other stations and this level was highest than other parts of plant in the same station and other stations. There was positive correlation between petroleum hydrocarbons in soil and plant parts indicated that the plants obtained the TPH from the soil. The total nitrogen was high levels (2.31mg/l) in tomatoes plant in Garmat Ali station while the lowest levels (1.33mg/l ) was in shuaiba station . Total phosphorus was higher in Abu kasibe (0.25mg/l ) and low levels (0.11mg/l ) in Safwan. The percentage of dry mass observed in this order Abu kasibe > Garma Ali > Safwan > shuaiba . The bioconcentration factor (BCF) and Translocation factor (TF) which is very important parameters to check the ability of plants for phytoremediation have been calculated.
