The major purpose of this research was to investigate the main effects of waste water from the El- Wafaeyya drain (polluted site) on some primary and secondary metabolites, nutritional and heavy metal levels, photosynthetic pigments, and seedy fruit quality. Irrigated Psidium guajava trees acquired much higher amounts of Fe, Mn, Zn, Cu, Pb, Co, and Cd than those irrigated with clean water. In contrast, total photosynthetic pigments in P. guajava leaves watered with contaminated water were significantly lower than in the control. Total protein and total carbohydrates were found in higher concentrations in the leaves of the control location. Proline, free amino acids, antioxidants, total phenolics, total flavonoids, and tannins were found in abundance in tree leaves treated with contaminated water. The opposite was true in the case of total alkaloids and saponins. When it comes to fruits, the negative effects were concentrated on the economic output and number of fruits rather than their weight and size. Irrigation with dirty water, on the other hand, resulted in lower levels of water, total proteins, total carbohydrates, and vitamin A and C, but higher levels of dietary fibres. The use of both qualitative and quantitative electrophoretic pattern analysis improves the reliability of the findings in terms of the numerous genotoxic consequences that these drugs can cause. The use of P. guajava fruits harvested from polluted places for human purposes must be avoided since they are harmful, dangerous, and risky.
