Abstract:

An oral dose of 1000 mg/kg body weight/day is mentioned in Organisation for Economic Cooperation and Development (OECD) and European Union (EU) guidelines as a default maximum dose in limit tests for studies on reproductive toxicity. This paper investigated whether upper range human exposure data from the workplace are supportive of this limit dose as an upper limit of possible human exposure. To this end, published exposure data as well as data from the database MEGA of the German “Berufsgenossenschaften” were evaluated. These data indicate that exposure concentrations in the range of 500 to

Abstract:

Abstract South African occupational exposure limits for hazardous chemical agents were revised in 2021 and introduced some limit values that were lowered by up to 99.2% when compared with the previously applicable limit values. A descriptive study was conducted as desk research to identify exposure limits from a list typically applicable to carcinogens, mutagens, teratogens, or sensitizers, called maximum limits, that were lowered substantially. The percentage reduction in maximum limits were calculated to identify those that were reduced by more than 50%, constituting more stringent limits. T

Abstract:

Abstract Occupational hygiene service providers and companies worldwide have been collecting thousands of exposure monitoring samples and not leveraging the lessons learned from exposure monitoring results. The exposure monitoring results are often not representative of actual exposures. Precious resources are wasted in collecting exposure monitoring samples when not needed based on, for example, previous exposure monitoring results and chemical properties. For example, inhalation of phosphoric acid exposure is rarely a concern as phosphoric acid vapor pressure is low (0.03 mmHg (20 °C). Expos

For the employer the greatest concern is to comply with the exposure limit value, but also exceeding the action value will cause implications.

Abstract Occupational exposure limits (OELs) are key tools in occupational hygiene to protect workers who may be exposed to health hazards in their workplace. Typically OELs are given a single value for 8 hr-TWA, 15 min STEL or Ceiling. Although it is suggested that these values are not the fine lines between safe and unsafe, they are generally perceived as the fine lines of whether it is acceptable in the fields. If a worker’s exposure exceeds the OELs, employers and employees hardly know how dangerous it is by simply comparing it with OELs. For example, if the exposure level is 1.2X OELs, th

Abstract:

Uranium trioxide, produced industrially, was administered to rats either by inhalation or direct injection of an aqueous suspension into the lungs. The results: 1 show that uranium was cleared rapidly from the lungs, mainly to the blood; 2 show that distribution of uranium among body tissues, and the fraction of the systemic content excreted in urine, was similar to that obtained for other transportable hexavalent uranium compounds; 3 suggest that urine monitoring data would be of more value than lung radioactivity counting measurements for assessing occupational human exposure; 4 indicate tha

Abstract:

Anesthesia providers are frequently exposed to radiation during routine patient care in the operating room and remote anesthetizing locations. Eighty-two percent of anesthesiology residents (n = 57 responders) at our institution had a “high” or “very high” concern about the level of ionizing radiation exposure, and 94% indicated interest in educational materials about radiation safety. This article highlights key learning points related to basic physical principles, effects of ionizing radiation, radiation exposure measurement, occupational dose limits, considerations during pregnancy, sources

Abstract:

Pneumoconiosis is one of the most common occupational lung diseases in Thailand and worldwide. Workplace exposure to asbestos and silica is the main contributor to the prevalence of occupational pneumoconiosis. The aim of this study was to review the prevalence of occupational exposure to asbestos and silica among industrial workers in Thailand. A scoping literature review searched MEDLINE and universities in Thailand. The results from screening 113 were 11 studies selected for further review. Ten studies were cross-sectional and only one study was a retrospective cohort study. Four studies fo

Abstract:

In general, biological exposure limits are only used for the promotion and preservation of workers' health and are not applied for diagnostic purposes. However, the issue is controversial for certain types of occupational poisoning. This paper proposes the utilization of biological exposure limits currently applied to blood lead levels in Brazil as an important criterion for diagnosing occupational lead poisoning. The author argues that contrary to the traditional clinical criterion, one should deal with the diagnostic problem of lead poisoning from an epidemiological perspective, using the cu
