“…Kidney stones were the second important purpose of using MP. The water composition of this area shows high mineral concentrations [27] that can contribute to an insufficient high urine volume and consequently to a decline in the concentration of lithogenic substances and a high risk of calcium oxalate crystallization [28]. Furthermore, this region is characterized by a high level of temperature in summer, which can also be associated with kidney lithiasis stone attacks cases increase [29].…”

Aim:The aim of this study was to identify different plants used in folk medicine for treating pain, inflammatory diseases, diabetes and kidney stones by the population of Zagora province, in Southeastern of Morocco. This investigation was undertaken during more than 2 years started in 2013 and ended in 2015. Materials and Methods: A total of 1400 person with different ages between 20 and 80 years, in 12 areas, was included in this survey; 348 were diabetics, 292 were suffering from kidney stones and 760 healthy. Data collected was separated in two parts. The first part concerned interviewee information's (age, sex, and level of education) and the second part was designed for plants uses (vernacular names, uses, parts used, and mode of preparation). Use value (UV), fidelity level and family UV (FUV) were calculated. Results: We inventoried 83 plants species belonging to 40 families that were used. Ranunculaceae family showed the highest significance (FUV = 0.36). Six species with the highest UV were Zygophyllum gaetulum L. We identified 50 species used for treating or managing pain, 45 for diabetes, 19 for kidney stone, 7 for treating inflammatory diseases, and only 3 species that were recognized with hallucinogenic effects. Conclusions: This study shows that folk medicine in Zagora still occupies a high level in primary health care. Data collected may help to preserve knowledge about different plants used and their mode of preparation.

Areas located within the hot, arid zone are characterized by extremely low availability of fresh water. In the Tunisian regions of Kébili and Medenine, deep-water sources and connate groundwater constitute its main sources. Surface waters, as well as shallow groundwaters found in those areas, are affected by a high level of salinity, which significantly reduces their use for either drinking or agriculture. Due to intensifying droughts the rainwater accumulation system, neither fulfils the needs of residents nor the developing agriculture. Waters in the oases of El Faour (Kébili) and Beni Kchedeche (Medenine) were analyzed in 2017 to find out their chemical composition, as well as their suitability for irrigation. The chemical composition of the investigated waters is dominated by the Na + , Ca 2+ , Cland SO 4 3ions. The value of electrolytic conductivity (EC) was found to be within the range of 1100 to 6400 μS/cm. The highest concentration of nitrate was 44 mg/L. Salinity indicators classified this water mainly as unsuitable for irrigation on the basis of sodium adsorption ratio (SAR) and EC, sodium total percentage (%Na) and Kelly's ratio (KR). The iron concentration in all examined wells exceeded the recommended values set for potable water and ranged from 0.6 to 2.5 mg/L.

“…This reduction induces dissolved SO 4 2− to become isotopically enriched in 34 S with decreasing concentration (Canfield, 2001;Chambers and Trudinger, 1979;Gammons et al, 2013;Nakai and Jensen, 1964). Strontium (Sr) isotope compositions are usually reported using the ratio of 87 Sr/ 86 Sr, which is a useful tracer for identifying hydrogeochemical processes, especially the origin and flow pathways of groundwater (Armstrong et al, 1998;Bohlke and Horan, 2000;Chapman et al, 2013;Heidel et al, 2007;Khaska et al, 2013;Nordstrom et al, 1992;Paces and Wurster, 2014;Raiber et al, 2009;Vilomet et al, 2001;Warner et al, 2013). Moreover, the suitability of this tracer is enhanced by the lack of Sr isotope fractionation during hydrogeological processes (Barbieri and Morotti, 2003;Naftz et al, 1997;Negrel et al, 2001).…”
