Threshold limit value for exposure of the hand to vibration [PDF]

open access: bronzeThe Journal of the Acoustical Society of America, 1983
Habitual exposure of the hand to vibration frequently leads to tingling and numbness followed by episodes of finger blanching, with reduction in manual dexterity and tactile sensitivity, and damage to soft tissue and joints in severe cases. The dose-effect relations reported elsewhere for the development of vibration-induced white finger [A. J. Brammer,

Exposure Limit Values for Nanomaterials—Capacity and Willingness of Users to Apply a Precautionary Approach [PDF]

open access: greenJournal of Occupational and Environmental Hygiene, 2013
In the European Union, the legal obligation for employers to provide a safe workplace for processing manufactured nanomaterials is a challenge when there is a lack of hazard information. The attitude of key stakeholders in industry, trade unions, branch and employers' organizations, and government policy advisors toward nano reference values (NRVs) has

Blue Light Hazard: are exposure limit values protective enough for newborn infants? [PDF]

open access: greenRadioprotection, 2018
Blue Light Hazard is an emerging concern for health of population. Nevertheless, acute exposure to blue rays from artificial light is well taken into account by normative requirements applicable to lamps engineering and risk for general population is low.

Bivariate Left-Censored Measurements in Biomonitoring: A Bayesian Model for the Determination of Biological Limit Values Based on Occupational Exposure Limits [PDF]

open access: greenAnnals of Work Exposures and Health, 2017
Biological limit values (BLV) are often determined from the occupational exposure limits (OEL) in modelling biological data obtained on a number of exposed subjects based on measurements of air exposure. In order to obtain such BLVs, biomonitoring studies are conducted collecting simultaneously biological and airborne measurements to these substances ...

Assessment of Occupational Exposure to Chemicals by Air Sampling for Comparison With Limit Values: The Influence of Sampling Strategy [PDF]

open access: bronzeThe Annals of Occupational Hygiene, 2014
This study was aimed at quantifying the impact of sampling duration and the number of measurements taken on the quality of assessing occupational exposure to toluene. To this end, a measurement database was built, based on four campaigns carried out in an industrial printing facility.

1459 The effect of below exposure noise threshold limit value to acute stress [PDF]

open access: bronzeVibration and Noise, 2018
Introduction This study aims to examine the possibility of the effect of noise with intensity below the threshold value to stress. Method The study is a quasi-experimental involved 108 subjects divided into 6 noise exposure groups of control, 0 dBA, 70 dBA, 75 dBA, 80 dBA and 85 dBA in 15 min exposure.

Threshold limit values (TLVs) for exposure of the hand to vibration: A subject revisited [PDF]

open access: closedThe Journal of the Acoustical Society of America, 1990
Threshold limit values (TLVs) designed to restrict the severity of the vascular component of the hand-arm vibration syndrome (HAVS) have been proposed by the American Conference of Governmental Industrial Hygienists. A proposed revision to the TLVs would employ the same frequency-weighted accelerations measured according to ISO 5349 (1986), and daily ...

Occupational exposure limit for silver nanoparticles: considerations on the derivation of a general health-based value

open access: goldNanotoxicology, 2016
With the increased production and widespread commercial use of silver nanoparticles (AgNPs), human and environmental exposures to silver nanoparticles are inevitably increasing. In particular, persons manufacturing and handling silver nanoparticles and silver nanoparticle containing products are at risk of exposure, potentially resulting in health ...
