Background levels of soil beryllium in several countries

Area of Science:

• Geochemistry
• Environmental Science
• Soil Science

Background:

• Understanding elemental distribution in soils is crucial for environmental and geological studies.
• Beryllium and aluminium are key elements with varying concentrations globally.
• Establishing baseline levels in uncontaminated soils provides a reference for pollution assessment.

Purpose of the Study:

• To determine and report beryllium and aluminium concentrations in uncontaminated soils from diverse global locations.
• To establish a tentative average beryllium content for surface soils worldwide.
• To investigate the relationship between beryllium and aluminium content in soils.

Main Methods:

• Soil samples were collected from six countries: Thailand, Indonesia, New Zealand, Brazil, former Yugoslavia, and former USSR.
• Beryllium and aluminium content were analyzed in surface and subsoil samples.
• Statistical analysis, including calculation of means, ranges, and correlation coefficients, was performed.

Main Results:

• Beryllium concentrations in surface soils varied by country, with the former Yugoslavia showing the highest mean (3.52 μg g(-1)).
• A tentative average beryllium content of 1.42 μg g(-1) was calculated for uncontaminated surface soils.
• Subsoil beryllium content was higher than surface soil content in New Zealand, Yugoslavia, and Japan.
• A significant positive correlation (r=0.505, p < 0.001) was found between beryllium and aluminium content in all soil samples.

Conclusions:

• Global surface soils exhibit variable beryllium concentrations, with regional differences noted.
• The established tentative average provides a benchmark for beryllium in uncontaminated soils.
• The positive correlation suggests a co-distribution or geochemical link between beryllium and aluminium in soils.
