This study analyzed the anthropogenic influences on hydrochemical composition characteristics of groundwater in Xiamen City, Fujian province, China, and their evolution. Based data 1993 2019‒2021, this identified indices using mathematical statistical analysis methods, such as contrast coefficient, standard deviation, Mahalanobis distance. The analytical results are summarized follows: (1) numb...

the optical spectrum band positions and epr parameters (g factors g//, g^ and hyperfine structure constants a// and a^) for vo2+ ions in zn(antipyrine)2(no3)2 are theoretically studied from the complete diagonalization (of energy matrix) method (cdm) and the perturbation theory method (ptm). in the two methods, the contributions from the spin–orbit (so) coupling of central 3dn ion and ligand ar...

in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...

Lead (Pb) is one of the most abundant heavy metal (HM) pollutants, which can penetrate the plant through the root and then enter the food chain causing potential health risks for human beings. Radish is an important root vegetable crop worldwide. To investigate the mechanism underlying plant response to Pb stress in radish, the protein profile changes of radish roots respectively upon Pb(NO3)2 ...

The current study was conducted to investigate the efficiency of olive mill waste-derived biochar and its silica-embedded nutrient-loaded derivatives in immobilizing lead (Pb) improving nutrients availability contaminated sandy loam soils. Biochar produced at 500 °C latterly modified with silica enriched (P N). An incubation experiment for a period 45 days observe dynamics heavy metals nutrient...

Two new nano-sized lead(II) and mercury(II) coordination polymers, [Pb(2-bpdh)(NO3)2(H2O)]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza- 2,4-hexadiene)} and [Hg(4-bpdb)(SCN)2]n (2); (4-bpdb= 1,4-bis(4- pyridyl)-3,4-diaza-1,3-butadiene) were synthesized by a sonochemical method. The structure of 1 may be considered coordination polymer of lead(II) and Single crystal X–ray analysis of compound ...
