Increasing salinity of the groundwater is one of major challenges faced by agricultural sector in West Bank/Palestine. This study was carried out in the lower Jordan Valley （lJV） under greenhouse field condition, where an area of 0.12 ha was irrigated with 3.5 dS/m magnetic treated water during the growing season 2012/2013. The results of this pilot project show that there are significant increases in the yield of red and yellow bell pepper of about 20% and 18% on fresh weight basis, respectively. Water use efficiency increased by 15% and an increase in shelf time of 7 d were also recorded. The chlorophyll content raised significantly in the leaves of treated plants compared to the controlled one by 2.5 mg/g. Bell pepper irrigated with magnetic water produces 37% more four champers than that of the controlled one. On the other hand, there were no clear significant effects on the height of the plant, number of fruits, distance between nods, size of fruits, number and thickness of walls and sugar contents. Applying visible/near infrared （VIS/N｜R） spectroscopy test shows that it is possible to distinguish between treated and controlled bell pepper fruits. Multivariate data analysis （MVDA） method was used to test the classification of chemical elements in the fruit and it was found that treated and controlled fruit samples are divided into two groups according to their water treatment. An increase in all nutrient concentrations was found in fruits irrigated with magnetic treated water compared with the controlled one. Further testing is needed especially by involving other variables such as decreasing the volume of irrigated water and fertilizers.

Impact of long-Term Atrazine Use on Groundwater Safety in Jilin Province, China

Journal of Integrative Agriculture 2013年第2期12卷 305-313页

The long-lasting application of representative herbicide atrazine （ATR） has given rise to the accumulation of its residues in the groundwater. To investigate the impact of long-term ATR use on groundwater safety, the residues of ATR and its metabolites, desethylatrazine （DEA）, deisopropylatrazine （dia） and hydroxyatrazine （ha） were monitored in groundwater and top soil at the major corn growing region of Qian＇an and Gongzhuling in Jilin Province, China. The residues of the target compounds were analyzed by UPlC-MS/MS. The limits of detection （lODs） ofATR, DEA, dia, and ha were 0.5, 0.5, 5, and 0.5 ng l-1 in groundwater and 0.33, 0.33, 3.3, and 0.33 μg kg-1 in soil. The target compounds were found in 94% of groundwater samples and 100% of soil samples. The compounds detected most frequently in groundwater were ATR （89%）, DEA （64%） and ha （17%）, whereas in soil were ATR （97%）, DEA （36%） and ha （97%）. dia was not detected in any determined groundwater and soil sample. Average residues were 106.8 ng l-1 for ATR, 0.9 ng l-1 for DEA and 0.3 ng l-1 for ha in groundwater, whereas 11.1 μg kg-1 for ATR, 0.4 μg kg-1 for DEA and 7.8 μg kg-1 for ha in soil. ATR residues detected in groundwater samples were below standards for drinking water quality （GB5749-2006, 2 μg l-1）, while the total residues of ATR and its chloro-s-triazine metabolites （DEA and dia） were below current WHO （World Health Organization） guideline value （GV, 0.1 mg l-1）. In addition, concentrations of ha in groundwater were determined below current WHO GV （0.2 mg l-1）. The results indicated that ATR is safe to be used in Jilin Province under the current application scheme. However, total residues of ATR and DEA were detected in nearly all wells, thus, it is necessary to pay attention on groundwater monitoring for ATR and its metabolites.

目的探讨新疆地区维吾尔族妊娠期糖尿病(GDM)妇女不同妊娠阶段血清性激素结合球蛋白(SHBG)表达,及对维吾尔族GDM诊断价值。方法选择2018年8月~2019年8月新疆医科大学第二附属医院维吾尔族GDM患者100例为观察组,同期健康体检维吾尔族孕妇100名为对照组。比较两组孕早、中期和晚期血清SHBG、空腹血糖、空腹胰岛素、糖化血红蛋白(HbA1c)和空腹C肽水平,计算HOma-IR值,分析孕早期SHBG水平与其他指标的相关性;受试者工作曲线(ROC)分析孕早期SHBG水平对GDM的诊断价值。结果观察组孕早、中期和晚期血清SHBG水平明显低于对照组,差异均有统计学意义(均Pma-IR值高于对照组,差异均有统计学意义(均Pma-IR值呈显著负相关(r=-0.869,P<0.01)。孕早期SHBG水平诊断GDM的曲线下面积为0.877。结论在不同妊娠阶段,新疆地区维吾尔族GDM孕妇血清SHBG水平均较低,且与IR程度呈负相关,孕早期血清SHBG水平可作为早期诊断GDM的重要生化指标。
