To explore the contributions of chemical components in particulate matter Lhasa, size distribution characteristics components, such as carbonaceous species (organic carbon, OC; elemental EC), water-soluble ions (NH4+, Cl−, SO42−, and NO3−) trace elements (Na, Ca, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, K, Mg, Pb), were investigated from August 2018 to May 2019. Principal component analysis (PCA) was...

The paper presents the results of physicochemical analyses spring waters in Postomia River valley (Northwest Poland). Multivariate statistical methods, i.e., cluster analysis (CA) and principal component (PCA) were used to assess spatial distribution similarities differences concentrations individual elements. Concentrations macro elements (MEs), trace (TEs) rare-earth (REEs) analysed concernin...

Black carbon (BC) and PM2.5 chemical characterizations are crucial for insight into their impact on the health of exposed population. sampling was carried out over selected residential sites Jamshedpur (JSR) Kharagpur (KGP), east India, during winter season. Seven elements (SO42?, Cl?, Na+, NO3?, K+, Ca2+, Mg2+) were analyzed using ion chromatography (IC). also done at two different in JSR KGP ...

In this study, water samples were collected from 10 thermal and non-thermal springs of Mahalat setting during four periods in 2011. The discharge rates of these springs vary from 2 l/s to 45 l/s and their temperature range from an average minimum of 18oC to maximum 47oC. Spring water is high in SO4-Cl and this is related to gypsum dissolution. Correlation coefficient, principal component analys...

Located in a semiarid region of the Hulun Buir League China’s Inner Mongolia Autonomous Region, Hailar Basin is with less precipitation, where groundwater most important water supply source. It to study characteristics and hydrogeochemical processes for better management resources. Fluorine (F), arsenic (As), uranium (U) cocontamination currently exists Basin, China. To understand concentration...

A particular river-whiting phenomenon occurred in the early 2000s in the Xiaoche River and since then it has been reoccurring from June to November each year. Residents were surprised by this phenomenon and worried about it. This study was designed to reveal the forming mechanism of the river-whiting phenomenon. A comparison of T, EC, ORP, DO, TDS and δ34S in the culvert water and discharge pip...

BACKGROUND The importance of the isatinic quinolyl hydrazones arises from incorporating the quinoline ring with the indole ring. Quinoline ring has therapeutic and biological activities whereas, the indole ring occurs in Jasmine flowers and Orange blossoms. As a ligand, the isatin moiety is potentially ambidentate and can coordinate the metal ions either through its lactam or lactim forms. In a...
