Özet
Orontes (Asi) River, which is one of the important water Sources in the Middle East. rises in Lebanon, runs through Syria and Turkey and discharges into the Mediterranean Sea at the southern edge of Samandag, Hatay in Turkey. In this study, it is purposed to determine spatial and temporal variations of physicochemical properties and metal contents of Orontes River. Water samples were taken from 12 sampling sites on the Orontes River at six different periods. Water temperatures were measured at each site at the sampling times. Electrical conductivity (EC), pH. total dissolved solids (TDS), Na, K, Ca, Mg. Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, P, Pb, Zn, CO(3), HCO(3), and Cl determinations: were made on the water samples. Heavy metal concentrations of the Orontes River were found to be considerably low owing to the relatively low industrial activity in the basin. However, the presence of high concentrations of P especially around Antakya city was possibly due to the untreated sewage sludge discharge into this river. The seasonal and spatial fluctuations in the pH values were not excessive. The EC values at the sampling sites were found to be on the higher range in terms of salinity (754.5-1699.6 mu S cm(-1)). Both the EC and TDS values increased markedly in the rainy season probably due to the contribution of salts leaching from nearby lands. It can be concluded that soluble salts and the high P content are the most critical respective parameters threatening the agriculture and aquatic life in the lower Orontes River basin.
