“…Several studies have focused on the effects of irrigation with treated wastewater and the application of olive mill wastewater and moderate saline water on soil chemical properties (Al-Absi et al, 2009;Mechri et al, 2011;Bedbabis et al, 2010aBedbabis et al, , 2014 and little information is known about the effects of TWW on chemical properties of a cultivated sandy-silty soil. Studies on the effect of TWW on olive's growth, productivity and oil quality in Tunisia are scarce (Bedbabis et al, 2009(Bedbabis et al, , 2010aBen Rouina et al, 2011).…”

“…Pb was undetectable in the olive oil of both cultivars. Even though the contents of Pb in the leaves of the two cultivars were detectable, it was less than the maximum permissible concentration in olive leaves 23. The undetectable concentration could be explained as follows: only a fraction of the soil Pb is taken up by olive trees, and most of the Pb taken up is accumulated in the roots and not translocated into above‐ground parts.…”

BACKGROUND: An alternative plan for saving scarce water could include use of non-conventional water resources such as reclaimed wastewater originating from wastewater treatment plants. The main health risks are associated with contamination of crops by wastewater due to its chemical composition. Therefore, the effect of recycled effluent irrigation was investigated on mineral composition and quality of olive oil of two local olive cultivars under field conditions during two complete cycles.

“…26 In Israel, the majority of irrigated olive orchards are irrigated with non-potable, marginal to low-quality water, mainly RWW, 18 and similar trends are nowadays seen in additional regions in the Mediterranean basin. 16,30,31 Several studies have focused on effects of irrigation with either fresh or saline water on the composition and quality of olive oils. 13,15,29,[32][33][34] The rising use of RWW for olive irrigation in the Mediterranean calls for intensive study.…”

BACKGROUND Irrigation of olives increases fruit and oil yields. Due to scarcity of freshwater, low‐quality water including recycled wastewater (RWW) is utilized in orchards. Here, effects of irrigation with RWW and of fertilization on the composition and quality of olive oil were studied. RESULTS Long‐term RWW irrigation of ‘Barnea’ and ‘Leccino’ olive had no significant negative effects on either oil composition or quality parameters, including free fatty acids (FFAs), peroxide value (PV), total phenolics content (TPC), fatty acid profiles and organoleptic characteristics. The average FFA contents for both cultivars were less than 0.8% during most of the experimental period, except the seasons 2009 and 2012–2013 for Barnea where the values were raised up to 1.4%. The measured PV levels were less than 9 and 5 mmol O2 kg‐1 oil for Barnea and Leccino, respectively. In the last season of the experiment for each cultivar, higher TPC were observed in oils obtained from RWW irrigation with reduced fertilization (Re–) as compared to the treatments with the recommended fertilization [freshwater irrigation (Fr) and RWW irrigation (Re+) with standard dose of fertilizers], where the TPC increment exceeded 70% in Barnea and 25% in Leccino. The treatments had only minor effects on the fatty acid profile, reflected in slightly altered levels of C18:2 and C18:3 fatty acids. CONCLUSION The use of RWW, combined with the consideration of nutrients arriving with such water to provide appropriate fertilization, was found suitable for olive irrigation to ensure optimal yields while preserving oil quality. © 2019 Society of Chemical Industry
