AIR: Inhalation of airborne chemicals

Description

Estimates the Intake rate by inhalation of airborne chemicals (vapor phase) [mg/Kg*day]

Usage

AIR(CA = 1, IR = 20, ET = 24, EF = 350, ED = 24, BW = 70, AT = 365 * 70)

Value

Intake rate by inhalation of airborne chemicals (vapor phase) I [mg/Kg*day] - Object class "numeric"

Arguments

CA

Chemical concentrtion in air [mg/m^3]

IR

Inhalation Rate [m^3/hour]

ET

Exposure time [hours/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)

Examples

## Estimated absorbed dose for the estimation of carcinogenic effects using 
# the default variables (EPA 2011) for a chemical air concentration 
# of 0.2 mg/m^3

AIR ( CA=0.2)

# For a systemic effect:

AIR ( CA=0.2, AT=24*365)

# Specifying all the parameters for the carcinogenic case

AIR ( CA=0.2, IR=25, ET = 24, EF = 300, ED = 24, BW = 85)
