In 1974 the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration joined to complete exposure standards promulgated by federal regulations. In that effort NIOSH scientists developed an acc

The effect of spray-painting gun choice, high volume-low pressure (HVLP) or conventional, on solvent and particulate overspray concentrations was experimentally studied in a downdraft spray-painting booth. This experiment was conducted by repeatedly

Method 25 for the Determination of Hazardous Substances (MDHS 25) of the Health and Safety Executive of the United Kingdom attempts to identify and quantify all isocyanate species in an air sample. Isocyanate species are derivatized with 1-(2-methoxy

Performance tests for evaluating respirable aerosol sampling methods were developed. The tests entail measurement of the flow-dependent collection efficiency of the aerosol size-discriminating part of the sampler using an aerodynamic particle sizer.

The purpose of this research was to evaluate the feasibility of using auxiliary (local) ventilation, in conjunction with a scavenging system, as a means of controlling nitrous oxide (N2O) in a dental clinic. Four systems, one system using only scaven

Alternative approaches are developed for analyzing errors in evaluating sampling and analytical methods. The aim is to decide with given confidence (e.g., 90%) that an accuracy criterion is met. The accuracy criterion specifies the fraction (e.g., 95

Excessive exposures to air contaminants can be determined by conventional sampling with pumps and sampling media; however, such results do not provide insights into the reasons for the excessive exposures. The analog or digital output from direct-rea

Two direct-on-filter methods for the determination of respirable α-quartz in air by X-ray powder diffraction (XRD) were compared with NIOSH Method 7500. The two direct-on-filter methods are direct-on-silver membrane filter and direct-on-mixed cellul

A commercial rhodizonate-based test kit was evaluated for its potential use in the detection of lead in airborne particulate samples at work sites. Over 350 air samples were collected at abrasive blasting lead paint abatement sites using cellulose es
