It is important to monitor a statistically representative population. Workers are often divided into "similar exposure groups" with similar work assignments and contaminant exposure profiles. Data must be validated, reported, and communicated. Exposure monitoring may be targeted to individual workers, or areas. [1]: 21, 46–47, 58
Essentially, a JEM comprises a list of levels of exposure to a variety of harmful (or potentially harmful) agents for selected occupational titles. In large population-based epidemiological studies, JEMs may be used as a quick and systematic means of converting coded occupational data (job titles) into a matrix of possible exposures, [ 1 ...
In summary, the report called for more rigorous health-based criteria for selecting chemicals to include in biomonitoring studies; the development of tools and techniques to improve risk-based interpretation and communication of biomonitoring data; integration of biomonitoring into exposure assessment and epidemiological research; and ...
'Exposure assessment' and 'exposure analysis' are often used as synonyms in many practical contexts. Risk is a function of exposure and hazard. For example, even for an extremely toxic (high hazard) substance, the risk of an adverse outcome is unlikely if exposures are near zero. Conversely, a moderately toxic substance may present substantial ...
A common stomach bug is surging, according to new data from the US Centers for Disease Control and Prevention. In the week of December 5, there were 91 outbreaks of norovirus reported, up from 69 ...
Limits for short-term exposure, such as STELs or CVs, are defined only if there is a particular acute toxicity associated with a substance. These limits are set by the American Conference of Governmental Industrial Hygienists (ACGIH) and the Occupational Safety and Health Administration (OSHA), based on experimental data. The values set by ...
The process of conducting a dietary exposure assessment involves the determination of the chemical residues on a particular food or foods and the calculation of the dietary exposure to these chemicals based on consumption data for the specified food or foods. [2] / In the most simplified form, a dietary exposure assessment can be summarized ...
Australian homicide detectives are investigating the suspected "targeted double murder" of a Sydney couple. On Tuesday, Dec. 17., New South Wales (NSW) police confirmed a second body had been ...
