Overview

The geochemical survey reveals selenium bioavailability and speciation in soil, highlighting implications for sustainable agriculture.

Key Points

  • This research aims to investigate the distribution and bioavailability of selenium in soils and crops in Heshan District.
  • Conducted a 1:50,000 geochemical land quality survey in Heshan District
  • Analyzed soil and crop samples for selenium content and speciation
  • Mapped the spatial distribution of selenium in relation to geological strata
  • Significant selenium enrichment found in central-eastern soils
  • Low average bioavailable selenium concentration at 0.074 mg/kg
  • Crops like wheat and maize showed moderate to strong selenium enrichment, with no heavy metal contamination detected.
