SIR: Chemical intake by accidental soil ingestion

In EnviroPRA: Environmental Probabilistic Risk Assessment Tools

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]

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)
