Geochemical Model And Normalization For Heavy Metals In The Bottom Sediments, Dubai, UAE.

Abstract

Dubai creek can be considered as the focal point of Dubai. It has great importance for trading and aesthetic values. Total and leachable heavy metals (Cd, Co, Ni, Pb and Zn), organic carbon and total carbonate were studied in the bottom sediments of the creek. Pollution Load Index, statistical analysis, were used in order to quantify the pollution load as well as to discriminate the data into significant groups. Normalization of the data using organic carbon and total carbonate was done in order to reduce the effect of grain size. Quantification and methods normalization allow the sampling stations to be differentiated into two groups. The first group of clustered stations are those located in the upper channel up to Abra, including the Gomera beach, off creek and the creek mouth. The second groups of stations are those from Jadaf, including the lagoon area. It is concluded that there is an increase in the pollution load with time, however comparing the present results with the previous data, Dubai creek can not be considered as a polluted region. Care should be taking in order to reduce the pollution load in future.
