DWIR {EnviroPRA2}

Chemical intake by Drinking Water

Description

Estimates the chemical Intake rate by Drinking Water [mg/Kg*day]

Usage

DWIR(CW = 1, IRW = 2, EF = 350, ED = 24, BW = 80, AT = 365 * 70)

Arguments

CW

Chemical concentrtion in water [mg/L]

IRW

Water Ingestion Rate [L/Day]

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 drinking water I [mg/Kg*day] - Object class "numeric"

Examples

# Estimate the dermal absorbed dose during swiming in waters with a carcinogenic chemical
# (water concentration of 250 mg/m^3)

DWIR ( CW = 250)

# For a systemic effect:

DWIR ( CW= 250, AT=24*365)

# Specifying all the parameters for the carcinogenic case
