“…OMW ranks among the most perilous effluents, presenting substantial environmental risks due to its complex, pollutant-rich composition. Because of the high levels of contaminants such as phenolic chemicals and solid suspension, it is also one of the hardest to treat [5,6]. These compounds are estimated to be present in concentrations of approxi- Our decision to utilize titanium dioxide (TiO 2 ), synthesized through the sol-gel process, is based on its proven efficacy, as documented in the existing literature (Table 2).…”

“…For the traditional pressing system involving three-phase centrifugation and continuous de-pitted extraction, the amount of wastewater produced surpasses 47 kg for every 100 kg of olives [3,4]. This agro-industrial effluent presents significant challenges in terms of weight and management complexity [5][6][7]. It comprises a dark, malodorous, and turbid aqueous liquid containing emulsified grease and a high organic content [8].…”

The olive mill wastewater (OMW) treatment process is modeled and optimized through new design of experiments (DOE). The first step of the process is coagulation–flocculation using three coagulants (modeled with the mixture design) followed by photo-degradation (modelled with the full factorial design). Based on this methodology, we successfully established a direct correlation between the system’s composition during the coagulation–flocculation step and the conditions of the photo-catalytic degradation step. Three coagulants are used in this study, Fe3+ solution, lime, and cactus juice, and two parameters are considered for the photo-degradation conditions: dilution and catalyst mass. Utilizing a sophisticated quadratic model, the analysis of the two observed responses reveals the ideal parameters for achieving maximum efficiency in coagulation–flocculation and photo-degradation processes. This is attained using a quasi-equal mixture of limewater and cactus juice, exclusively. To achieve an optimal photo-catalytic degradation, it is essential to maintain a minimal dilution rate while employing an elevated concentration of TiO2. It was found that the experimental tests validations were in good concordance with the mathematical predictions (a decolorization of 92.57 ± 0.90% and an organic degradation of 96.19 ± 0.97%).

The oleic industry is one of the most polluting in food industry sector. An easy treatment of this waste is Coagulation–flocculation. Photo-catalysis can be used as complementary treatment to improve the water quality and make it reused. We optimize this method to treat mill wastewater collected from the region of Mahdia, by varying the conditions and studying their effects. Organic pollutant were removed and the final quality of water were under the imposed norm NT 106-02.

“…In general, biomarkers of oxidative stress provide valuable information on the effects of pollutants and serve as an early warning system before measurable effects occur at the individual or population level. Oxidative stress biomarkers have been applied to various soil species, mostly earthworms [30][31][32][33][34][35], enchytraeids [19,[36][37][38][39], arthropods Porcellionides pruinosus [40,41], and Folsomia candida [27,[42][43][44].…”

Azoxystrobin (AZO) is widely used to prevent and treat fungal diseases in important crops but can also impact non-target organisms, including mammals, amphibians, aquatic, and soil organisms. Collembolans play important roles in ecosystems as decomposers, fungal feeders, and regulators of microbes. This study aimed to investigate the effects of AZO on Collembola Folsomia candida using a reproduction test and assess biomarker responses over different time intervals (3, 5, 7, 14, and 28 days). Results showed AZO negatively affected reproduction at concentrations of 50, 100, and 200 mg./kg, resulting in decreases of 48.3%, 64.5%, and 81.3%, respectively, compared to the control. Adult survival remained unaffected. The estimated EC50 (reproduction) in artificial soil was 61.28 mg kg−1. Biomarker responses varied with concentration and time. Protein and glycogen concentrations increased with exposure time, while lipid content was affected initially but returned to control levels by day 28. Oxidative stress biomarkers (CAT, SOD, GST, TBARS) indicated AZO induced oxidative stress, intensifying over time. After 28 days, MDA concentrations were significantly elevated compared to the control, suggesting the antioxidant system is overwhelmed which caused damage to lipid membranes. This study showed that azoxystrobin caused negative effects at molecular and population level on non-target species of Collembola.
