Peak Inhalation Exposure Metrics Used in Occupational Epidemiologic and Exposure Studies

Assessment of physical work load in epidemiologic studies: common measurement metrics for exposure assessment.

There are many possible means of determining exposure ranging from self-reports of physical exposure to measures of muscle activations and estimated spinal loads. In epidemiologic studies, issues of validity make instrumented measures preferable, however issues of cost and practicability tend to force investigators to less costly but less valid and less reliable measures of exposure, such as se...

Health Risk Assessment Guidance for Metals Herag Assessment of Occupational Inhalation Exposure and Systemic Inhalation Absorption

[Occupational exposure to biological agents intentionally used in Polish enterprises].

BACKGROUND The paper presents the intentional use of biological agents for industrial, diagnostic and research purposes in Polish enterprises. MATERIAL AND METHODS The National Register of Biological Agents (Krajowy Rejestr Czynników Biologicznych - KRCB) is an online database that collects the data on the intentional use of biological agents at work in Poland. RESULTS As of December 2013 t...

Inhalation exposure of animals.

Relative advantages and disadvantages and important design criteria for various exposure methods are presented. Five types of exposures are discussed: whole-body chambers, head-only exposures, nose or mouth-only methods, lung-only exposures, and partial-lung exposures. Design considerations covered include: air cleaning and conditioning; construction materials; losses of exposure materials; eve...

Inhalation exposure methodology.

Modern man is being confronted with an ever-increasing inventory of potentially toxic airborne substances. Exposures to these atmospheric contaminants occur in residential and commercial settings, as well as in the workplace. In order to study the toxicity of such materials, a special technology relating to inhalation exposure systems has evolved. The purpose of this paper is to provide a descr...
