in NO3-N varied over a wide range of 3.2-110.12
mg/L (Table 1). The minimum (3.2 mg/L) and
maximum (110.12 mg/L) NO3-N were recorded
during autumn months with a mean NO3-N of 9.93
mg/L (Table 2). The seasonal mean values of NO3-N
during winter and summer were 26.61 and 41.01 mg/L,
respectively (Table 2).
Fluctuations in PO4-P (mg/L) values were similar to
NO3-N. The minimum (0.12 mg/L) and maximum
(18.92 mg/L) PO4-P levels were observed during
summer months with a mean value of 5.30 mg/L
(Table 2). The seasonal mean values of PO4-P(3.73
mg/L) during winter and summer were 3.00 and 5.3
mg/L, respectively as shown in Table. 2.
The E.C values in this study range from 1.14-4.07
dS/m..s while the EC values for natural water are
between 0.5 – 1.5 dS/m (Gems 1997) , that is why
Shatt AL-Arab is considered as a saline water in
comparison with other rivers of the world. Previous
studies show that EC. range from 1.469-2.364 dS/m
during 1980 ( Polservice 1980) .while it range from
2.282-2.510 dS/m during 2004 (Al-Mayahi 2005).
1.53-5.3 dS/m (Al-Kazaeh 2014) ,1.57-10.85 dS/m
Al-Hejuje (2015).
In stream water, dissolved solids consist of calcium,
chlorides, nitrate, phosphorus, iron, sulfur, and other
ions particles that will pass through a filter with pores
of around 2 microns (0.002 cm) in size. Suspended
solids include silt and clay particles, plankton, algae,
