Research/Original Article (دارای رتبه معتبر)

Purpose :

Because of the steep shortage in freshwater supply in the Israeli-occupied West Bank, raw wastewater (RWW) has been widely used to irrigate vegetable crops. This study aims to detect the effects of irrigation with raw wastewater on crops cultivated in Wadi Al-Far’a, Palestine.


 A total of 300 soil, crop, and RWW samples were randomly collected from Wadi al-Far'a, an area with a long history of irrigating crops with raw wastewater. A survey questionnaire was also used to collect data on the parasites-infected farmer.

Results :

Results showed that percentages of contaminated vegetables, soil, and RWW samples were 10.2%, 27.0%, and 47.5%, respectively. Crops leave indicate contamination with parasite eggs depending on their contact with surface soil, e.g., contamination of zucchini (leaves rest on surface soil) and mallow (upright plant stand) was 19.0% and 2.0%, respectively. The highest and lowest soil contamination with parasites eggs pertained to A. lumbricoides (30.0%) and T. trichiurid (19.2%).

Conclusion :

Certain mitigation measures should be used to limit the danger of farmers becoming infected with common parasites, particularly Ascaris lumbricoides. Farmers' awareness of the manner of parasite transmission and adherence to safety regulations should be among them.
