Heavy metals in soils with a high geological background are usually considered to be of natural origin, while increases in soil heavy metals due to industrial and agricultural activities are considered to be anthropogenic contamination. How can you accurately identify both types of soil?
Accurately identifying heavy metal geological high background soils and anthropogenic contaminated soils requires a combination of field observations, laboratory analyses, and data interpretation.
Here's a step-by-step guide to help you with this process:
Remember that accurate identification of geological high background soils and anthropogenic contaminated soils requires a multidisciplinary approach, combining fieldwork, laboratory analysis, and data interpretation. Collaboration with experts and adherence to regulatory guidelines are crucial to ensure reliable results.
To accurately identify heavy metal geological high background soils and anthropogenic contaminated soils, various methods can be used such as soil sampling, geophysical methods, remote sensing, historical data, and field observations. It is important to use a combination of these methods to identify and mitigate potential health and environmental risks associated with heavy metal contamination.
It is possible to differentiate between geological soils with a high geological background and soils contaminated by human action by using heavy metal concentrations and distinguishing between them according to the values of heavy metals. Read (McLennan.2001).
Soils by human action have higher concentrations and are on the surface of the earth’s crust as a result of extraction, while geological soils have a high background in the ground and have limited values of minerals.
When evaluating the geological formation and in a comprehensive way a soil, to relate the concentration of heavy metals with its edaphological characteristics, the processes of erosion-sedimentation-contamination must necessarily be evaluated.
A pedological survey must be taken into account to identify the types of soils accompanied by an analysis of their natural conditions and their influence on the appearance of heavy metals in significant concentrations that significantly affect the quality of this soil.
for identify and quantify the heavy metals in soil, the best option is to collect the soil sample and chemical analysis for heavy metals.for this AAS and ICP-MS are the best options. this provide the complete picture and also easy to identify whether these are natural or anthropogenic.
Yes, it helped me with precise concentrations
However, when measuring, CQ/QA.
