Due to the fact that strontium (Sr) is not involved in the scope of supervision of drinking water in China, the Sr concentration in public drinking water and its related health risks have been neglected for a long time. In this research, public drinking water samples were collected from 314 cities across the country to reveal the concentration and spatial distribution of Sr in public drinking water. In addition, the Monte Carlo method (a statistical simulation method) was applied to evaluate the Sr intake from drinking water and human health risks among different age groups and different regions. As shown in the results, the Sr was in the concentration range of 0.005-3.11 mg/L with a mean value of 0.360 mg/L. There were significant differences in the Sr concentration in different regions; in general, it was high in the north and low in the south. The Sr intakes of infants, children, teens, and adults from drinking water were 0.273, 0.503, 0.633, and 0.784 mg/day, respectively. There was a significant positiveied to risk control and management of public drinking water.The dynamics of poverty have become a controversial issue and one of the most common socio-economic problems in global economies, especially in developing economies as a whole. As per the importance of precise dilemma, the current study examines single as well as multidimensional poverty in the agro-climatic zones of Punjab, Pakistan, for the last 8 years from 2011-2012 to 2018-2019 by utilizing four available latest HIES (Household Integrated Economic Survey) datasets taken from the Pakistan Bureau of Statistics (PBS). This study uses a couple of indexing methods, namely FGT (1984) and Alkire and Foster (2007). Temporal analysis of the first measure of poverty demonstrates that with a shorter (longer) time gap, poverty presents a hybrid (declining) trend in the uni-dimensional spectrum in the province of Punjab and its agro-climatic zones. While population decomposition for uni-dimensional poverty validates that residences of cotton-wheat Punjab and lower intensity Punjab is the major contributor to overall province poverty. Thus, to diminish poverty in a single-dimensional context, it is the need of time to take emergency steps like uplift economic growth, lessen income inequalities, and create job opportunities by the government for the improvement of the living standard of the residences of the overall province with special consideration on both these most affected zones. Similarly, calculations of the second measure of multidimensional poverty reveal that poverty also presents a hybrid (declining) trend with a shorter (longer) span of time in the overall province and all agro-climatic zones with the exception of the wheat-rice zone. However, dimensional decomposition for multidimensional poverty index demarcates that education and health are the major contributors to MDP, and declining the households' deprivation in both these dimensions is relatively helpful to nippy fall in poverty in the study area.Integrated rice-crayfish systems are expanding rapidly and are the most widely applied planting-breeding modes in Jianghan Plain in China. We conducted nutrient use efficiency, economic, and emergy analysis of three rice production modes, namely, rice monoculture (RM), rice-crayfish rotation (RCR), and rice-crayfish coculture (RCC), in Jingzhou City, which is located in the Jianghan Plain. Compared with RM mode, rice-crayfish systems using the RCR and RCC modes increased rice yield by 5-7%, showed more than 8% higher chemical nutrient use efficiency, and increased the value-to-cost ratio from 1.5-fold to 2.7-fold and the benefit-cost ratio from 2.5-fold to 3.8-fold, while decreasing irrigation water consumption and land occupation by 31% and 82-86%, respectively. RCC resulted in 10% higher crayfish yield, 12% higher phosphorus use efficiency, and 38% higher feed use efficiency than RCR. However, compared with RM, rice-crayfish systems decreased renewable fraction by 10-14%, emergy yield ratio by 9%, and emergy sustainability index by 23-26%, and they increased environmental loading ratio to 18-23%. Labor and service, fertilizer utilization, and machine and tools play important roles in these negative environmental effects. Scenario analysis showed that the rice-crayfish systems increased sustainability index by 38-45%. The technical training of new planting-breeding technology should be adopted by farmers for the efficient use of fertilizers and improvement of food yield. This study suggests that rice‑crayfish systems are not a panacea to sustain cleaner food production.The precipitation of Cu(II) by phosphate and the influence of dissolved organic matter (DOM) on the precipitation are essential for the fate of Cu(II) in aquatic environments. In this study, the influence of DOM on the reaction of phosphate with Cu(II) was investigated. Here, 51.61%, 29.75%, and 24.32% of the added Cu(II) (50 μM) precipitated without DOM and with the addition of fulvic acid (FA) and humic acid (HA), respectively, owing to the reaction with phosphate (50 μM). Excitation-emission matrix spectroscopy-parallel factor (PARAFAC) and two-dimensional ultraviolet-visible correlation spectroscopy analyses were conducted to characterize the influence of DOM on the precipitation of Cu(II) with phosphate. One humic-like and two protein-like fluorescent components were identified by the PARAFAC model for FA, whereas two humic-like fluorescent components and one protein-like fluorescent component were validated for HA. The humic-like components had primary roles, whereas the protein-like components had secondary roles in limiting the precipitation of Cu(II) with phosphate. Cu(II) binding to DOM chromophores initially occurred at shorter wavelengths, and then at longer wavelengths. Phenolic and carboxylic constituents had important roles, and HA exhibited more binding sites than FA. Therefore, humic-like fluorescent components and chromophores containing phenolic and carboxylic groups and functional groups with peaks at short wavelengths (200-220 nm) were primarily responsible for restricting the precipitation of Cu(II) with phosphate.Continental glacier melts directly influence the environment, resulting in sea-level rise affecting the settlements along the coast. The increase in global warming and constant change in the glacier mass grabbed the attention of researchers in understanding the evolution and distribution of glaciers. Despite the increase in the number of glacier studies, the difficulty is experienced by the researchers in understanding the supra-glacial debris cover and its characteristics. Supraglacial debris cover affects surface melt by increasing and decreasing ablation under thin and thick debris cover. In the present study, estimation of supraglacial debris cover (SDC) over Austre Brøggerbreen and Vestre Brøggerbreen glaciers of Ny-Ålesund is carried out with the aid of Landsat 5/7/8 datasets between 2000 and 2020. Supraglacial debris-cover is mapped using NDSI and band ratio techniques based on thresholding and it is estimated that Austre Brøggerbreen and Vestre Brøggerbreen glaciers are covered by 7.29% and 15.19% of SDC respectively. Results obtained are validated by a field visit to Arctic glacier, which is the first of its kind enhancing India's scientific credentials in Polar research.Diabetes mellitus is considered a set of diseases that lead to high glucose level due to the absolute or relative absence of insulin. The study investigated the antioxidant activity and antidiabetic effect of phlorotannins extracted from brown seaweed Cystoseira compressa. Phlorotannins were extracted from C. compressa. It was confirmed by 2,4 dimethoxy benzaldehyde assay (DMBA), ultraviolet spectra, Fourier transform infrared spectroscopy, and ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The free radical scavenging activity of phlorotannins was estimated by total antioxidant capacity, 1,1-diphenyl-2-picrylhydrazyl radical-scavenging activity, and 2,2 azino-bis3-ethylbenthiazoline-6-sulfonic acid assays. Four groups of albino rats used in this study include control normal, control phlorotannins extract, diabetic by intraperitoneally administering of streptozotocin, and diabetic treatment with 60 mg/kg of phlorotannin extract after 4 weeks of diabetes induction. The main compound identified by UPLC-MS/MS in C. [https://www.selleckchem.com/products/rimiducid-ap1903.html read more] compressa extract belonged to the fuhalol. C. compressa extract showed high antioxidant properties. Phlorotannins significantly decreased serum glucose, liver malondialdehyde, and α-amylase, glucosidase activities. However, total antioxidant capacity, serum insulin, hepatic glutathione, and AMPKα2 expression in skeletal muscle were improved compared to the diabetic group. The histopathological examination showed that phlorotannins markedly reduced damage in β cells of pancreases. Phlorotannins from C. compressa have efficient antioxidant activity and the antidiabetic effect that may be utilized in human health.The suitable location selection for artificial recharge with treated wastewater is an important issue, especially in arid and semiarid countries as a result of rapid population growth, increasing water demand, excessive use of groundwater resources, and mismanagement of limited freshwater resources. However, the determination of suitable sites is a complex process affected the environment, social, and economic concerns. This study shows the integration of the geographic information system (GIS) and the multi-criteria evaluation (MCE) to determine a suitable artificial recharge site with treated wastewater for Ariana, Tunisia. According to the literature review, data available on artificial recharge and regional characteristics, thirteen constraints and five factors were determined to choose the best potential site for artificial recharge. The constraints helped the determination of unsuitable sites with Boolean logic, while factors, standardized using fuzzy logic and weighted with the analytic hierarchy process (AHP), helped to identify suitable locations. All criteria were overlaid on a decision structure after two scenarios based on environment and economic were identified with a weighted linear combination (WLC) that selects the suitable sites for artificial recharge. The results indicated that three potential sites were suitable for artificial recharge with treated wastewater. Finally, the ELECTRE III method was used to classify the three determining potential areas to order the best locations for aquifer recharge with treated water according to their characteristics from higher to lower weighted distance from the road, geometric form of the site, cost of the site, and distance from wetlands.Insect-pollinated plants are essential for honey bees to feed their brood. In agricultural landscapes, honey bees and other pollinators are often exposed to pesticides used for cultivation. In order to gain more insight into the fluctuation of pesticide loads, 102 daily pollen samples were collected between April and July 2018 in a fruit-growing area in Southern Germany. Samples were analyzed with respect to more than 260 pesticides using a multi-residue pesticide analysis method. Almost 90% of the analyzed pollen samples featured between one and thirteen different pesticides. In total, 29 pesticides were detected at maximum concentrations of up to 4500 ng/g pollen. Maximum residual concentrations of most pesticides were observed during April and the first half of May, as well as during the second half of June. In most cases, serial data of pesticide residuals were detected for approximately 10 subsequent days with two or three maximum values, which were several folds higher than concentrations on the days before and thereafter.
