The effects of phosphates rock (PR) with different particle sizes {D97<4.26 (the diameters of 97% of the particles are less than 4.26 µm.), <36.83, <71.12 and <101.43 µm} and different concentration (2.5% and 5% content of try soil weight) on immobilizing heavy metal-contaminated soils by a perennial ryegrass greenhouse experiment are conducted. Results indicate that remediation effect of applying 5% content is more significant than 2.5%. Ryegrass biomass in shoots in the former applying content is much larger than the latter and for both roots and shoots, PR reduces the absorption and accumulation of Pb, Cu and Zn, but no significant influence on Cd. While adding the same amount of different sizes of PR doesn’t show significant differences between these treatments. Pb content at 5% level of the finest size of PR is the minimum, decreased by 33% and 56% compared to the control in roots and shoots respectively, which was also suitable for Zn, decreased by 12.65% and 39.61% respectively.

In this study, the geochemical properties of heavy metal-contaminated soils from a Korean military shooting range were analyzed. The chemical behavior of heavy metals was determined by analyzing the soil pH, heavy metal concentration, mineral composition, and Pb isotopes. In total, 24 soil samples were collected from a Korean military shooting range. The soil samples consist of quartz, albite, microcline, muscovite/illite, kaolinite, chlorite, and calcite. Lead minerals, such as hydrocerussite and anglesite, which are indicative of a transformation into secondary mineral phases, were not observed. All soils were strongly contaminated with Pb with minor concentrations of Cu, Ni, Cd, and Zn. Arsenic was rarely detected. The obtained results are indicated that the soils from the shooting range are contaminated with heavy metals and have evidences of different degree of anthropogenic Pb sources. This study is crucial for the evaluation of heavy metal-contaminated soils in shooting ranges and their environmental effect as well as for the establishment of management strategies for the mitigation of environmental risks.
