Abstract

The quality of irrigation water available to irrigators significantly impacts crops and yields. Therefore, there is a need to understand irrigation water quality better. The present study mainly focuses on assessing the suitability of water in five bore wells of the Aldabwat agriculture project in Alshatti, Libya. The well water samples were evaluated for agricultural uses according to the universal standard classification. Separate bore wells have been analyzed for various water quality indices, including exchangeable sodium percent (SSP or %Na), residual sodium carbonate (RSC or RA), Kelly’s ratio, permeability index, potential salinity (PS), magnesium hazard, total dissolved solids, and total hardness. Most of the wells fall under the moderate water category for irrigation purposes. The analysed water was specified as having a low restriction according to the water quality index (IWQ index).

Abstract

The Tasawa agricultural project was constructed to produce grains in the southern region. The project has employed various chemical fertilizers to enhance agricultural production. However, the use of these fertilizers may lead to the accumulation of heavy metals in the soil. Soil samples taken from the project site showed a mean concentration of Chromium (Cr), Copper (Cu), Cadmium (Cd), Manganese (Mn), Zinc (Zn), Nickel (Ni), and Iron (Fe) at 25.97±11.02, 0.95±0.94, 4.37±3.23, 12.26±7.59, 2.21±2.98, 9.15±10.93, and 267.50±84.96 mg/kg, respectively. The geochemical pollution index (Igeo) shows the non-pollution of Cu, Cd and Zn, while Cr, Mn, Ni, and Fe are unpolluted or slightly polluted. Pearson correlation coefficient indicated a significant positive correlation between Fe-Mn (r=.987**), a significant negative correlation between Mn-Cr (r = -.943**) and a negative correlation between Fe-Cr (r= -.878*).

Abstract

Consuming vegetables as food offers rapid and least means of providing adequate vitamins, minerals, and fibers. Vegetables used as food include those used in making soups or as integral parts of the primary sources of a meal. Leafy vegetables occupy a significant place in the human diet. Environmental exposure to heavy metals is a well-known risk factor for human health. The concentration of the heavy metals (Cu, Pb, Cd, and Cr) in vegetables from the Sebha market was determined using Atomic Absorption Spectroscopy AAS). In the Sebha local market, different vegetable types from different locations are marketed. Therefore this investigation was conducted to study the state of the accumulation of some heavy metals such as Cu, Cd, Pb and Cr. in some selected vegetables which include Solanum tuberosum (Potatoes), Allium cepa L. (Onion), Daucus Corota L. (Carrot), Cucurbita Pepo (Courgette), Solanum melongena L. (Eggplant), Lactuca sativa L. (Lettuce), Petroselinum crispum (mill.) Nym. (Parsley) and Spinacea oleracea (Spinach). The mean levels of these heavy metals ranged from 0.0-0.03, 0.0-2.36 and 0.0.0-8.13. ppm for Pb, Cd, and Cr. respectively. Among the vegetables studied, Cd and Cr exceeded the allowable limits recommended by WHO/FAO in some vegetables, whereas Cu and Pb concentrations are under the detectable limit. Statistical analysis shows a positive correlation between Cd and Cr at 0.01 and between Cd and Cr, Cd and Pb at 0.05.

Abstract

The study examined water samples from wells in Sebha, analyzing their physicochemical properties such as pH, EC, TDS, Cl-, Na+, K+, Ca2+, Mg2+, NO3-, HCO3-, TH, and SO42-. The results revealed significant increases in EC, TDS, Cl-, Na+, K+, Ca2+, NO3-, TH, and SO42- concentrations. However, pH, Mg2+, and HCO3- remained within permissible limits set by Libyan and World Health Organization standards. The study also noted more pronounced changes in the physicochemical properties of water from wells in Abd-Alkafi1, Abd-Alkafi2, and Aljadeed on the western side of Sebha compared to those in Alnaserayah and Hajara on the eastern side. Correlation analysis showed strong positive correlations between EC-TDS, TH-Ca2+, and K+-Na+ at a significant level of p<0.01, and positive correlations at a significant level of p<0.05 between EC- Cl-, Cl--HCO3-, Cl-- K+, Cl--Na+, SO42- - Na+, HCO3-- NO3-, and HCO3-- K+. The strong correlation between Na+ and Cl- indicated high concentrations of these ions in most samples, likely formed from chloride salts through chemical weathering. Similarly, a positive correlation between SO4-- and Na+ suggested that some of these ions resulted from weathering of magnesium and sodium minerals. The Water Quality Index (WQI) categorized water from Alnaserayah and Hajara as suitable for drinking, while water from Abd-Alkafi2, Abd-Alkafi1, and Aljadeed was deemed poor quality. Comparing the current results to a 2001 study revealed a significant increase in the measured elements' concentrations and deterioration in water quality.
