Geostatistical methods identified high lead (Pb) concentrations in soil, revealing public health risks in urban Brazil. This approach aids environmental planning and health policy decisions.

Area of Science:

  • Environmental Science
  • Geostatistics
  • Public Health

Context:

  • Urban and industrial areas present risks from heavy metal soil contamination.
  • Lead (Pb) contamination is a significant environmental concern in populated regions.
  • Baixada Santista, São Paulo State, Brazil, is a major urban and industrial concentration.

Purpose:

  • To apply geostatistical methods for public health risk mapping.
  • To identify areas with elevated heavy metal concentrations, specifically lead (Pb).
  • To assess soil contamination levels against regulatory standards.

Summary:

  • Spatial distribution maps of lead (Pb) were created using ordinary kriging.
  • Indicative kriging identified soil sites exceeding maximum acceptable lead levels.
