Determining chemical air equivalency using silicone personal monitors.

ABSTRACT:

Background

Silicone personal samplers are increasingly being used to measure chemical exposures, but many of these studies do not attempt to calculate environmental concentrations.

Objective

Using measurements of silicone wristband uptake of organic chemicals from atmospheric exposure, create log K_sa and k_e predictive models based on empirical data to help develop air equivalency calculations for both volatile and semi-volatile organic compounds.

Methods

An atmospheric vapor generator and a custom exposure chamber were used to measure the uptake of organic chemicals into silicone wristbands under simulated indoor conditions. Log K_sa models were evaluated using repeated k-fold cross-validation. Air equivalency was compared between best-
