Exposure assessment is a branch of environmental science and occupational hygiene that focuses on the processes that take place at the interface between the environment containing the contaminant of interest and the organism being considered. These are the final steps in the path to release an environmental contaminant, through transport to its ...
The exposure assessment is initiated by selecting the appropriate exposure limit averaging time and "decision statistic" for the agent. Typically the statistic for deciding acceptable exposure is chosen to be the majority (90%, 95% or 99%) of all exposures to be below the selected occupational exposure limit.
Environmental fate and transport, or how the hazard moves and changes in the environment after its release; Exposure point or area, or the place at which an exposed person comes into contact with the hazard; Exposure route, or the manner by which an exposed person comes into contact with the hazard (e.g., orally, dermally, or by inhalation)
Additionally, the Environmental Exposure Assessment Research Infrastructure (EIRENE) [33] is a collaborative effort consisting of 17 National Nodes representing around 50 institutions with complementary expertise. EIRENE aims to fill the gap in the European infrastructural landscape and pioneer the first EU infrastructure on the human exposome.
Exposure science can be used to support environmental epidemiology by better describing environmental exposures that may lead to a particular health outcome, identify common exposures whose health outcomes may be better understood through a toxicology study, or can be used in a risk assessment to determine whether current levels of exposure ...
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 ...
Environmental epidemiology is a branch of epidemiology concerned with determining how environmental exposures impact human health. [1] This field seeks to understand how various external risk factors may predispose to or protect against disease, illness, injury, developmental abnormalities, or death.
Calculated value of a chemical in the environment on the basis of exposure models such as the European Union System for the Evaluation of Substances (EUSES). Used in the context of Chemical Safety Assessments (CSA) and referenced in Chemical Safety Reports (CSR). PECs may be compared with Measured Environmental Concentrations (MEC) if available.
