Measured data are generally preferred to modelled estimates of exposure. Grouping and
read-across is already widely used and accepted approach in toxicology, but an appropriate …

In this study, 129 exposure situations (ESs) with six or more measured inhalation exposures
to dust from solids or vapour from liquids in occupational settings were compared with …

A broad array of research needs for improved retrospective exposure assessments for
occupational epidemiology studies have been identified in the sessions of this Workshop …

This paper demonstrates statistical methods that estimate measurement error from available
industrial hygiene data. Errors in measuring a continuous exposure variable may arise when …

As part of a larger study aimed at identifying the long-term changes in inhalation exposure
for selected hazardous substances in a number of industrial sectors within the UK, we have …

Objective: To evaluate three methods for assessing retrospective exposures of acrylonitrile
workers. Methods: Three methods used to develop historical exposure estimates for a …

Objectives This study examined whether it is possible to train occupational hygienists to
estimate inhalation exposures reliably from limited occupational information using a new …

Abstract Purpose of Review Exposure assessment efforts in population-based studies are
increasingly incorporating measurements. The published literature was reviewed to identify …

For many work situations only insufficient exposure data are available to perform proper risk
assessment. Because measuring worker exposure can be time consuming and resource …

Selecting a proper respirator requires determining the ratio of an employee's maximum use
concentration (MUC) divided by the occupational exposure limit of a chemical. Current …
