This study deals with the determination of total mercury concentration in the water
taken from three sites on Al-Kabeer Al-Shemaly River ( near the industrial area and Al-
Damat Lake, and 16 Tishreen Lake), also the effect of some physio-chemical p
arameters
including: DO, pH, T °C. of water in the three sites was studied.
Results showed that the total mercury concentration was low in general, where the
medium concentration in the three studied sites was 0.29 ppb and it was less than the
permission level of total mercury in the surface water(> 10 ppb), the higher value of the
medium concentration of total mercury(0.35, 0.31, 0.21)ppb was recorded in the Industrial
Area, Damat Lake, then 16 Tishreen Lake, respectively. For the changes in the total
concentration of mercury in the three studied sites during seasons of a year, was higher in
Summer comparing with other seasons. The results showed positive correlation coefficient
between the total mercury concentration and temperature, pH value, but it was negative
with DO in Summer.
