The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The
conce
ntrations of ions (Cl-1, SO4-2, NO2-1, NO3-1, PO4-3, K+1, Na+1) in five dams (Balloran, 16 Tishreen, Al-thawra, Alsafarkia and Alhweez) were studied. The results indicated that most of the ions showed significant difference in concentrations during 2002-2011.The ions concentrations in most studied dams increased. The increase related to characteristics of dams (location, capacity, the activities located around the dam…).
The environmental factors may have an effect on the contents of the active
materials in plants. Salinity is one of these factors that can have an influence through the calcium ion
which competes with the Na+, which in turn, affects the manufacture of alkaloids present in the Datura
stramunium.
