Variations of glaucine, quercetin and kaempferol contents in against AlO, NiO, and TiO nanoparticles.

The present study was designed to determine the glaucine, quercetin and kaempferol contents in the root and shoot parts of treated for 21 days with different concentrations of the nanoparticles (NPs), including titanium dioxide (TiO), alumina (AlO) and nickel oxide (NiO) by high-performance liquid chromatography (HPLC). Results showed a significant increase in the total flavonoid and total alkaloid content in treated plants. Glaucine content in shoot parts was significantly higher than the root parts.

Quantification of heavy metal pollution for environmental assessment of soil condition.

The aim of this study was to quantify heavy metal pollution for environmental assessment of soil quality using a flexible approach based on multivariate analysis. The study was conducted using 241 soil samples collected from agricultural, urban and rangeland areas in northwestern Iran. The heavy metals causing soil pollution (SP) in the study area were determined.
