Estimation of total hydrocarbon concentrations in water, sediments and two types of aquatic plants in Hor Al Huweiza in Maysan Governorate - Southern Iraq

Abstract

The present study was performed to have knowledge of Total Petrolum Hydrocarbons(TPHs) compounds pollution status in the water ,sediments and two species of aquatic plants (P.australis and T.domengensis). The samples were collected monthly for the period January 2017 until December 2017 from four different stations were selected in the study area . The study samples were collected monthly ,But The results was seasonaly.The concentrations of total petroleum hydrocarbons (TPHs)were measured by using spectrofluorometer. Concentrations of total petroleum hydrocarbons in water was ranged between 1.05 µg/l in the first station during summer and 6.78 µg/l in the first station during spring ,while in sediments they ranged between 4.83 µg/g dry weight in the first station during summer and 19.96 µg/g dry weight in the second station during winter.Concentration of TPHs in P.australis was ranged between 2.56 µg/g dry weight in the second station during winter and 10.456 µg/g dry weight in the third station during summer , while in T.domengensis their concetration was between 2.750 µg/g dry weight in the second station during winter and 8.150 µg/g dry weight in the third station during summer.The TPHs concentration in the p.australis are higher than the T.domengensis and the TPHs concentration in the samples of the study take the following order:Sediments > p.australis > T.domengensis > Water.It concluded from this study that the concetration of TPHs in all samples were in acceptable range>
