Soil accumulation parameters

Estimates the increment in topsoil lead concentration after a given period of operation, assuming all atmospheric deposition stays in the surface soil layer (no leaching, no erosion). Suitable for screening-level assessment.

Years of operation: 20

Soil depth (cm): 15

1 cm = surface (direct ingestion); 15 cm = root zone (vegetable crops); 30 cm = tilled (field crops).

Bulk density (g/cm³)

Default 1.3 g/cm³ for typical topsoil. Sandy soils ~1.5, organic-rich ~1.0.
