The pollution characteristics of Pb, Cd, Zn, Cu and Ni in soil of lead−zinc mining area were studied. The results indicate that the contamination degree followed the sequence of Cd>Pb>Zn>Ni>Cu and concentrations of Pb, Cd and Zn exceeded corresponding limits of the Chinese National Soil Environmental Quality Standard III. The soil was extremely polluted by Cd (Iego=5.26), moderately to heavily ...

The impact of mechanical site preparation (MSP) on soil biogeochemical structure in young larch plantations was investigated. Soil samples were collected in replicated plots comprising simple trenching, double trenching, mounding and inverting site preparation. Unlogged natural mixed forest areas were used as a reference. Analysis of soil nutrients, abundance of bacteria and gas exchanges unvei...

Nowadays Risk Management is a common practice in the Information Systems security field. It is usually supported by a Risk Assessment process, which is done at regular but unfortunately large intervals. This lack of a continuous Risk Assessment process in an ever-changing environment, such as Information Systems, tends to make Risk Management a more complex and less accurate task. In this paper...

Heavy metal (Cr, Ni, Cu, Zn, Cd, and Pb) pollution, fractionation, and ecological risks in the sediments of Lake Chaohu (Eastern China), its eleven inflowing rivers and its only outflowing river were studied. An improved BCR (proposed by the European Community Bureau of Reference) sequential extraction procedure was applied to fractionate heavy metals within sediments, a geoaccumulation index w...

Objectives : Since the risk of pollutants in soil environment may vary depending on characteristics, functions, and environmental conditions soil, site-specific ecological assessment (SERA) should be conducted to protect ecosystem from pollutants. It has been confirmed that each country is conducting SERAs based guidelines suitable for their own conditions. However, Korea, there a lack basis in...

As there is no scientific reason to discriminate between chemicals and radioactive substances in terms of environmental risk assessment methodology (ERA), it is now generally recognised (Garnier-Laplace et al., 2006) that the classical ERA method (EC, 2003) may be applied to both of these substances. This is of particular interest in the case of uranium that presents a double ecotoxicity, chemi...

The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...
