The degradation of groundwater quality has emerged as a significant global concern, impacting regions worldwide, including Pakistan. Thus, this study aimed to assess the suitability of groundwater for drinking purposes in UC Ratokot and Khairpur Juso. A total of twenty-five groundwater samples were collected from various villages within these regions, and both on-site and laboratory-based physicochemical analyses were conducted. Parameters such as color, odor, taste, sulfate (SO4), electrical conductivity (EC), pH, total hardness (TH), calcium (Ca), magnesium (Mg), and total dissolved solids (TDS) were assessed, with each sample's results compared against WHO standards. Analysis using two models, namely the Water Quality Index (WQI) and Synthetic Pollution Index (SPI), revealed insights into groundwater quality. Findings indicated that all samples exhibited no discernible external color or odor, with turbidity below 5 NTU. However, the taste of 68% of samples from 17 villages was notably bitter, rendering them unsuitable for consumption. Overall, results showed that 100%, 88%, 72%, 68%, 60%, 52%, and 52% of samples exceeded WHO limits for EC, TDS, Mg, Cl, Ca, TH, and SO4, respectively. Assessment based on the SPI revealed that 40%, 48%, 8%, and 4% of samples were classified as highly contaminated, unfit for drinking, slightly contaminated, and moderately contaminated, respectively. Similarly, the WQI categorized 12%, 36%, 40%, and 12% of groundwater samples as unfit for drinking water, very poor water, poor water, and good water, respectively.

“…For instance, an appropriate sorbent must be chosen to successfully apply the aforementioned SPME procedures in various settings. Other essential factors have been optimized in the SPME process for the selective extraction, reusability, and disposal of the sorbents with multiple analytes in environmental samples [ 86 ]. Due to its benefits, SPME has emerged as a viable alternative for detecting and specifying heavy metals.…”

Arsenic is a hazardous element that causes environmental pollution. Due to its toxicological effects, it is crucial to quantify and minimize the hazardous impact on the ecology. Despite the significant advances in analytical techniques, sample preparation is still crucial for determining target analytes in complex matrices. Several factors affect the direct analysis, such as trace-level analysis, advanced regulatory requirements, complexity of sample matrices, and incompatible with analytical instrumentation. Along with the development in the sample preparation process, microextraction methods play an essential role in the sample preparation process. Microextraction techniques (METs) are the newest green approach that replaces traditional sample preparation and preconcentration methods. METs have minimized the limitation of conventional sample preparation methods while keeping all their benefits. METs improve extraction efficacy, are fast, automated, use less amount of solvents, and are suitable for the environment. Microextraction techniques with less solvent consumption, such as solid phase microextraction (SPME) solvent-free methods, and liquid phase microextraction (LPME), are widely used in modern analytical procedures. SPME development focuses on synthesizing new sorbents and applying online sample preparation, whereas LPME research investigates the utilization of new solvents.

“…where WUE rc is the average value of crop WUE classified in kg m -3 , ET rc is the average value of RS ET classified in mm, a and b are coefficients of the quadratic parabola, ET c is crop water requirement in mm, ET 0 is the reference crop ET in mm, K c is the crop coefficient and ET q is the crop ET quota in mm. Here, the reference ET is calculated by using the FAO 56 Penman-Monteith's equation, and the crop coefficient is calculated by using the FAO 56 single-crop coefficient approach [49][50][51][52][53].…”

a b s t r a c tEstimation of regional water-saving potential is useful to develop the appropriate irrigation scheme and manage water resources. A new calculation method of water-saving potential for crops, based on the remotely sensed evapotranspiration (RS ET) data, is presented in this paper. The regional crop water production function was established based on RS ET and RS yield data. And the ET under the highest crop water use efficiency (WUE) was determined by its crop water production function. A regional crop ET quota was proposed by comparing crop water requirement and the ET under the highest crop WUE. The regional water-saving potential in agriculture was determined by selecting a regional crop ET quota as a standard. The results indicated that: (1) the ET quotas for winter wheat and summer maize were 417 and 313 mm, respectively; and (2) as far as the regional water-saving potential for crops is concerned, summer maize is the largest, at 11.77 million m 3 , followed by winter wheat, at 0.73 million m 3 ; and (3) the water-saving management area and water-saving volumes for main crops among different towns in Daxing county were analyzed. Meanwhile, the major water-saving management towns for wheat and maize were determined. The study will help planners and managers gaining a better insight into water management and water uses of crops.
