SIR {EnviroPRA2} | R Documentation |
Chemical intake by accidental soil ingestion
Description
Estimates the chemical Intake rate by accidental soil ingestion [mg/Kg*day]
Usage
SIR(CS = 1, IR = 100, FI = 1, EF = 350, ED = 24, BW = 80, AT = 365 * 70)
Arguments
CS |
Chemical concentrtion in soil [mg/Kg] |
IR |
Soil Ingestion Rate [mg/Day] |
FI |
Fraction ingested from contaminated source [-] |
EF |
Exposure frequency [day/yr] |
ED |
Exposure duration [yr] |
BW |
Body weight [Kg] |
AT |
Averaging time [day] (Note that for No carcinogenic effects AT should be equal to 365*ED) |
Value
Chemical intake rate by soil ingestion I [mg/Kg*day] - Object class "numeric"

Examples
# Ingestion rate for a children weighing 20 Kg who ingest 200 mg
# of soil every day, 250 days per year during 10 years. 95-UCL of
# Arsenic in soil is 25 mg/Kg
# Carcinogenic effects
SIR ( CS = 25, BW = 20, IR = 200, ED = 10, EF = 250)
# Systemic effects
SIR ( CS = 25, BW = 20, IR = 200, ED = 10, EF = 250, AT = 365*10)
