Possible enrichment process of Cd in the Se-rich soil area of Lanshan District, Shandong Province, China.

High cadmium (Cd) concentrations widely occured in selenium (Se)-rich soils, which has been an important obstacle in the usage of Se-rich soils. There is still no special information detailing the enrichment process and mechanism of Cd in Se-rich soils. 4474 soils and 21 rocks in Lanshan District were sampled to detect its enrichment process.

[Potential Source Identification and Ecological Risk Assessment of Heavy Metals in Surface Soil of Heze Oil Peony Planting Area Based on PMF-PCA/APCS and PERI].

To study the sources and potential risks of heavy metals in soils of characteristic agricultural product producing areas is of great significance for the scientific management and safe utilization of soil and crop resources. The contents of heavy metals As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in the 254 surface soil samples collected from the Heze oil peony planting area were determined. The content characteristics and correlation of heavy metals were analyzed using multivariate statistical methods.

The experimental study of fluorine-leaching ability of granite with different solutions: A new insight into the dynamic of groundwater fluorine levels along coastal zones.

Drinking-water fluorosis is universal along coastal zones, and the seawater or brine water intrusion is occasionally supposed to enrich groundwater fluorine levels. However, there is no conclusive proof, and the laws and mechanisms remain ambiguous. Granite, the common fluorine-bearing rock, is selected and experimented upon to reveal the characteristics and laws of fluorine's leaching ability during the intrusion of seawater.
