Figure 7: Interaction effect of the site [noncontaminated (NC) site, El-Saff wastewater-contaminated (WWC) site, and Suez industrial emission (SIE) site] and plant species (Tamarix nilotica and Zygophyllum coccineum) on nitrogen and phosphorus contents (ppm) in plants. Values followed by different letters within columns are significantly different at the 0.05 probability level.
