Abstract

A one-year monitoring program was carried out to assess the degree of pollution in three creeks on the northern coast of the United Arab Emirates (UAE), through measuring for chemical nutrients such as phosphate, ammonium, nitrate, nitrite and dissolved oxygen, in addition to enumerating selected microbial communities such as the heterotrophic bacteria, salt tolerant heterotrophic bacteria, Gram-negative bacteria, total coliform and faecal coliform bacteria. The results indicated that Dubai and Sharjah creeks have occasional unusually high nutrients levels with sharp fluctuations and wide spatial and temporal variations, suggesting the presence of an anthropogenic sources of pollution, creating these conditions, near the sampling sites. These sources includes several wastewater outlets and recreational facilities. Ajman creek had much less nutrients levels. The microbial counts in the three creeks had a distinct pattern where numbers peaked in mid spring (May) and autumn (October) and were relatively low during the summer and winter months. Total and faecal coliform fluctuated depending on several factors including the presence of nearby recreation and commercial areas, but were at no time consistently high. It was concluded that there is no major pollution problem in these creeks and recommendation were made to prevent it in the future.
