Exposure assessment is the process of estimating or measuring the magnitude, frequency and duration of exposure to an agent, along with the number and characteristics of the population exposed. Ideally, it describes the sources, pathways, routes, and the uncertainties in the assessment.
For example, after exposure to DDT, an organochlorine insecticide known to cause problems in the reproductive system, a woman may experience miscarriages, which can be linked to her previous exposure. Biomarkers of exposure are the most widely used because they can provide information on the route, pathway, and sometimes, even the source of ...
Exposure science is the study of the contact between humans (and other organisms) and harmful agents within their environment – whether it be chemical, physical, biological, behavioural or mental stressors – with the aim of identifying the causes and preventions of the adverse health effects they result in. [1] [2] This can include exposure within the home, workplace, outdoors or any other ...
Workplace exposure can be high concentration and lasting the duration of a shift and thus short-term whereas exposure outside of work is at low concentration and long-term. [46] The concentration of worker exposure is orders of magnitude higher than the general population (e.g., 4×10 10 particles per m 3 from extrusion 3D printers [ 47 ...
Identification of exposure pathways Relevant pathways of external and internal exposure Development and implementation of methods of estimating dose Data, assumptions, and methods of calculation used to estimate dose from relevant exposure pathways in assumed scenarios Evaluation of uncertainties in estimates of dose
Hazards have the potential to cause adverse effects only if they come into contact with populations that may be harmed. For this reason, hazard identification includes the development of a conceptual model of exposure. [8] Conceptual models communicate the pathway connecting sources of a given hazard to the potentially exposed population(s).
Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rather a matter of pharmacokinetics (concerning the processes of uptake, distribution, and elimination of drugs).
The core constructs of Ecosocial Theory are: Embodiment; Pathways to Embodiment; the cumulative interplay between exposure, resistance, and susceptibility; and agency and accountability. [2] [3] Further, the theory specifies that all constructs must be considered in concert, as they work together in a synergistic explanation of disease ...
