The resulting powders were then digested with concentrated 4MHN0 3 and analyzed for Fe, Zn, Pb, Cu, Mn, Cr, Cd As and Ag using bulk scientific atomic absorption spectrophotometry (AAS) model 210. Soil pH was determined in the laboratory by a Philips digital pH meter at a soil water ratio of 1:1. Soil organic matter content (OM)

Heavy metals such as Cu(II) are widespread in the environment, and the impact of heavy metals on the environment of soils depends on the ability of soils to immobilize these pollutants. It is necessary to investigate the mechanism of interaction between heavy metal and soil from a soil remediation perspective. In this study, a series of experiments were conducted to investigate …

 · Zn, Cd, Cu, and Pb are related to the mineralization. Specifically, Pb is related to galena, Zn and Cd are present in sphalerite, and Cu is mainly derived from the lesser proportion of chalcopyrite (CuS) in slag/ore. Furthermore, the presence of MDS indicates that there is an organic matter existing in the rocks, which is mainly derived from the interaction between …

Sango Studio in the woods. Sango Studio was established in 1987 in the rich forest of Nakijin Village, Okinawa Prefecture. As a licensed business in Okinawa Prefecture, it started with the purpose of establishing a new project to design coral as food and also to promote employment. With the support of many experts, we are studying the value of

The Pb, Zn, Cu mobility factor was significantly higher in SM soils than in SS soils. These results indicate that anthropic activities related to ore concentration and mining process lead to increased concentration of trace metals in surrounding soils, hence their mobility and bioavailability, this consists a potential risk to the environment and biota.
