VIboot: Chemical intake by ingestion of vegetables by bootstrap

In EnviroPRA: Environmental Probabilistic Risk Assessment Tools

Description

Estimates the chemical Intake rate by ingestion of contaminated fruits and vegetables [mg/Kg*day]

Usage

VIboot( n, CF, IR, FI, EF, ED, BW, AT)

Arguments

n	Output vector length
CF	Chemical concentrtion in food [mg/Kg]
IR	Vegetables Ingestion Rate [g / Kg * Day]
FI	Fraction ingested from contaminated source [-]
EF	Exposure frequency [day/yr]
ED	Exposure duration [yr]
BW	Body Weight [Kg]
AT	Averaging time [day] (For No carcinogenic effects AT = 365*ED)

Value

A vector of Chemical intake rate by vegetable ingestion I [mg/Kg*day]

Examples

# Assess the chemical intake by an adult that eats lettuce with a concentration of 2 mg/ Kg of a 
# chemical with non- carcinogenic effects in a maximum reasonable exposure scenario
# Figure out 10 data of Chemical concentration following a normal distribution (mean = 2, sd= 2)
# and 100 Body weight data that follow a normal distribution (mean = 70, sd = 15)

c <- rnorm( n= 10, mean = 2, sd = 2 )

b <- rnorm( n= 100, mean = 70, sd = 5 )

VIboot (n = 1000, CF = c, BW = b, AT = 365*24)
