Pollution Sources

Source identification of heavy metals in agricultural soils using small sample sizes, simple experimental procedures, and convenient analysis is urgently required. This study employed a simple source identification model using a visual comparison via radar plots, cluster analysis, principal component analysis, and a multiple linear regression model to determine the source of heavy metal pollution in soil samples from the Chang-Zhu-Tan urban agglomeration area of China. The elemental compositions of major pollution sources (atmospheric deposition, organic fertilizer, irrigation water, and tailings) were compared with soil samples from 11 study locations and the model was used to determine the relative contribution of different pollution sources at each sample site. The results showed that the model successfully calculated the contribution of different pollution sources at each site based on the pollution characteristics and contaminant transport rules of the region. The proposed method overcomes the requirement for extensive data and complex experimental procedures. Furthermore, the model can determine the source of heavy metal contamination in single or small plots, which is important for the prevention and control of heavy metal soil pollution and remediation at the plot scale.

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.

Sludge Application

The objectives of the present study were to determine the effects of the rate and timing of the application of sun-dried wastewater sludge from a food processing company's wastewater system on turfgrass growth and quality. The results were compared with those obtained with ammonium nitrate, and changes in the concentration of heavy metals and the presence of fecal coliform in turf soils after sun-dried wastewater sludge application were determined. The rate and the timing of sun-dried wastewater sludge and ammonium nitrate applications affected the turf color, quality, and clipping yield. Monthly fertilization resulted in a more uniform color and turf quality than infrequent spring and fall fertilization. Compared with the background values of base soils, heavy metals did not accumulate in sun-dried wastewater sludge-amended soils over the test period. Fecal coliform was not detected in sludge-amended soil samples, indicating that bacteria regrowth did not occur during the study period.

The Republic

This paper provides an analytical framework within which to understand the contrasting way farmers' interests are aggregated and articulated in Northern Ireland and the Republic of Ireland. The analysis draws on the dominant European literature on state-farmer relations which emphasizes the role of policy networks and explores whether the concepts of pluralism or corporatism best characterize policy making in the two states.
