Detector for phosphine at permissible levels in air
Journal of Agricultural and Food Chemistry, 1973A paper-strip detector has been developed for detecting maximum acceptable concentrations (0.05-0.3 p.p.m.) of phosphine in air. The strips are prepared by dipping them in a 1% solution of mercuric chloride in methyl yellow, and phosphine turns them red. Ammonia interferes with the proper development of the colour.

Permissible levels for occupational exposure; Basic concepts
International Archives of Occupational and Environmental Health, 1979The view point of the Dutch National MAC Commission and its Expert Committee on basic principles underlying permissible levels for occupational exposure is discussed. Standard setting is based upon a two-step procedure; viz., recommendation of acceptable levels (only health point of view), followed by establishment of accepted levels (policy decision).

Lead in soil: Recommended maximum permissible levels
Environmental Research, 1989Lead in soil has been recognized as a public health problem, particularly among children. In recent years, attention has been directed to cumulative adverse effects of lead at low levels of intake. Lead-contaminated soil and dust have been identified as important contributors to blood lead levels. Based on available data on blood lead and lead in soil,

Noise Exposure: Action Level Criteria as a Predictor of Permissible Exposure Level Criteria
American Industrial Hygiene Association Journal, 1983The adoption of the OSHA noise amendment has made it necessary to make two different noise exposure measurements. These are the employee's exposure with reference to the action level criteria, which requires a threshold of 80 dBA, and the employee's exposure with reference to the permissible exposure limit, which employs a 90 dBA threshold. In addition

Current Situation with Regard to Permissible Radiation Exposure Levels
Radiology, 1957This discussion will deal primarily with permissible radiation levels in relation to occupational exposure. While such levels are intimately related to those for the general population, this phase of the problem will not be discussed in detail. For the past twenty-five years this country has based its permissible occupational exposure levels on the ...
