Occupational exposure limits: A comparative study
Regulatory Toxicology and Pharmacology, 2008Occupational exposure limits (OELs) are used as an important regulatory instrument to protect workers' health from adverse effects of chemical exposures. The OELs mirror the outcome of the risk assessment and risk management performed by the standard setting actor. In this study we compared the OELs established by 18 different organisations or national

The concept of occupational exposure limits
Science of The Total Environment, 1991Germany was the first country to introduce occupational exposure limits (OEL) in 1886. A theoretical consideration for the existence of toxicological thresholds has been provided. Prerequisites for OELs are seen in: reversibility, existence of a threshold, deviation of (physiological) functions from normal to be regarded as "safe", knowledge about ...

Occupational exposure limits—at the crossroads
Occupational and Environmental Medicine, 2010Setting occupational exposure limits (OELs) for hazards in the workplace has been an integral component of worker health protection programs for many decades. These OELs have been established by many authoritative bodies around the world, such as the Threshold Limit Value Committee (TLV) of the American Conference of Governmental Industrial Hygienists (

Adjustment of occupational exposure limits for seasonal occupations
American Industrial Hygiene Association Journal, 1980A previously reported model for predicting adjustments to permissible exposure limits has been extended to include adjustments for seasonal occupations. On the basis of the model, no "credit" (i.e., increase in exposure limits) may be allowed for a short work season unless the biological half-life in hours of the agent of concern is greater than 38 W ...

Chemico-Biological Interactions, 2005
Benzene has become one of the most intensely regulated substances in the world. Its ubiquitous use as a solvent has led to many working populations being exposed; in the early days often in uncontrolled conditions, leading to high exposures. Current occupational exposures are tightly controlled and are largely confined to workers in the petrochemical ...

Safe Limits of Occupational and General Exposure to Radiation
Royal Society of Health Journal, 1961The biological effects of radiation are reviewed from the standpoint of safe limits of occupational and general exposure to radiation. lt is pointed out that many people are exposed to small doses of radiation through their occupations. Those occupationally exposed are all over age 18 and under the supervision of competent medical authorities.

On Strategies for Comparing Occupational Exposure Data to Limits
AIHAJ, 1996Parametric statistical approaches to assessing workplace exposure levels have typically focused either on the probability that a single measurement exceeds a limit or on whether the mean exposure for a population of workers exceeds a limit. This article reviews and clarifies some methods that have been proposed for each of these two approaches, on the ...

Occupational Exposure Limits in France
1990A scientific committee gathers experts, personnally appointed by the French Ministry of Labour, and administration representatives. This group critically reviews published data (industrial experience, experimental toxicological data, physicochemical properties, sampling and analysis capabilities, exposure/response relationship), discusses possibilities

Occupational Exposure Limits For Novel Work Schedules
American Industrial Hygiene Association Journal, 1975Work schedules other than 7 to 8 hr/day and 40 hr/week are being introduced in many industrial operations. Novel work schedules, such as four 10-hour workdays per week or three 12-hour workdays per week for three weeks followed by four 12-hour workdays for three weeks and several other plans are presently being used. The Threshold Limit Values (TLV) do

Consideration on a limit for lifetime occupational radiation exposure
Radiation and Environmental Biophysics, 1998Annual dose limits in occupational radiation exposure are merely a secondary constraint in addition to the primary rule of dose reduction and justification. The limits may, therefore, be reached only in rare, special cases. However, in principle, there might be cases in which the annual limit is continuously exhausted throughout a working life; a high ...
