Geochemical baselines in the assessment of soil contamination in Finland
This study provides an overview on the development of the guidelines and legislation related to soil contamination in Finland, with the main focus on geochemical baselines. The use of geochemical baseline surveys in the assessment soil contamination in Finland and in some other countries is briefly discussed and the current practices in Finland are presented. Finally, the geochemical baselines ...
متن کاملShifting Baselines, Local Impacts, and Global Change on Coral Reefs
I magine trying to understand the ecology of tropical rainforests by studying environmental changes and interactions among the surviving plants and animals on a vast cattle ranch in the center of a deforested Amazon, without any basic data on how the forest worked before it was cleared and burned. The soil would be baked dry or eroded away and the amount of rainfall would be greatly decreased. ...
متن کاملGlobal geochemical cycles of carbon, sulfur and oxygen.
Time resolved data on the carbon isotopic composition of carbonate minerals and the sulfur isotopic composition or sulfate minerals show a strong negative correlation during the Cretaceous. Carbonate minerals are isotopically heavy during this period while sulfate minerals are isotopically light. The implication is that carbon is being transferred from the oxidized, carbonate reservoir to the r...
متن کاملEnvironmental Baselines
A key element of the environmental monitoring programme of the International Seabed Authority is the establishment of environmental baselines. Regulation 28, paragraph 2 of the draft Mining Code states: "The Authority shall also develop procedures and guidelines for the establishment of environmental baselines against which to assess the likely effects on the marine environment of activities in...
متن کاملInfluence of geological setting on geochemical baselines of trace elements in soils. Application to soils of South–West Spain
A collection of 235 samples were taken from 115 sites (representing a density of 1 sampling site ca. 130 km) on rural soils derived from the major rock types in the southern Iberian Massif. The geochemical baselines of selected trace elements (As, Co, Cr, Cu, Ni, Pb and Zn) were determined on the b2 mm soil fraction. The sampling sites were not directly influenced by external pollution. Soil ge...
