A person's contact with a hazardous chemical in the course of employment through any route of entry (inhalation, ingestion, skin contact or absorption, etc.).
The time integral of the concentration of a toxicant which is in the immediate vicinity of various ports of entry (such as lung, GI tract and skin). Qualitatively, contact between a potentially harmful agent and a receptor (e.g., a human or other organism) that could be affected. [S. L. Brown
an event that occurs when there is contact at a boundary between a human being and the environment with a contaminant for a specific concentration for an interval of time: the units of exposure are concentration multiplied by time.
The amount of contact an individual has with asbestos fibers. Evaluation of exposure should take into account the factors of location of the asbestos containing building material (ACBM), potential duration of exposure, and potential exposure populations within the school. For example, intact boiler insulation in a boiler room accessed by maintenance or custodial personnel once per week would likely be given a relatively low exposure rating (i.e., 1).
Contact. No matter how dangerous a substance or activity, without exposure, it cannot harm you.
Condition of being subjected to something (e.g., an infectious agent) that could have a harmful effect.
Refers to contact with a substance under specific conditions of duration, concentration, and route of entry.
Exposure measures the interaction/contact of an organism and a compound over a specified time period. The area under the curve (AUC) is an important parameter for exposure. It is a measure of how much of a drug reaches the bloodstream in a set period of time. AUC is calculated by plotting drug blood concentration at various times during a 24-hour or longer period and then measuring the AUC between 0 and 24 hours.
Contact between a person and a chemical. Exposures are calculated as the amount of chemical available for absorption by a person.
Contact of an organism with a chemical. [see chronic toxicity and acute toxicity
The initial contact of the body with a substance.
coming into contact with a substance through inhalation, ingestion, or direct contact with the skin; may be acute or chronic
Any contact between a substance and an individual who has touched, breathed or swallowed it.
Anything you can be exposed to: a drug, a surgical procedure, time, sexual harassment, rounds, even a diagnostic test. Most commonly encountered in therapy, prognosis or harm studies where the EFFECT of an "exposure" is the subject of the study.
Exposure occurs whenever and wherever a person is subjected to electric, magnetic or electromagnetic fields or to contact currents other than those originating from phyiological processes in the body and other natural phenomena.
Coming into contact with a compound which may or may not result in a toxic effect. The main routes of exposure are by mouth, skin and by breathing.
A consumer's contact with an advertising format/campaign or POP unit
Contact with an agent through inhalation, ingestion, or touching. For example, exposure to radon is primarily through inhalation; exposure to lead is primarily through ingestion.
contact with a particular substance.
The condition of being subjected to something (e.g., an infectious agent) that could have an effect. A person exposed to M. tuberculosis does not necessarily become infected. Much of the work in a TB contact investigation is dedicated to learning who was exposed and, of these, who became infected.
Exposure Incident/Event means a specific eye, mouth, other mucous membrane, non-intact skin, or parenteral contact with blood or other potentially infectious materials that results from the performance of an employee's duties. (OSHA) Occupational Exposure means reasonably anticipated skin, eye, mucous membrane, or parenteral contact with blood or other potentially infectious materials that may result from the performance of an employee's duties. (OSHA)
is a measure of the contact between a toxicant and a living organism.
Exposure occurs when a person comes into contact with a hazard. The exposure can be to hazardous plant, such as to moving machinery like saw blades or to hazardous substances by contact with the skin or eyes, or working with VDUs.
Human contact with environmental contaminants in media including air, water, soil, and food.
A person's actual physical "contact" with an advertising medium or an advertising message.
Contact between an AGENT and a TARGET. Contact takes place at an EXPOSURE SURFACE over an EXPOSURE PERIOD.
Contact with a substance through inhalation, ingestion or some other means for a specific period of time.
Contact of an organism with a chemical, physical or geological agent.
The absorption of radiation or ingestion of a radionuclide. Acute exposure is generally accepted to be a large exposure received over a short period of time. Chronic exposure is low-level exposure received during a lifetime.
Contact with a pesticide.
Contact with a chemical. Some common routes of exposure are dermal (skin), oral (by mouth) and inhalation (breathing).
Compare? Radiation or pollutants that come into contact with the body and present a potential health threat. The most common routes of exposure are through the skin, mouth, or by inhalation.
Human contact with environmental contaminants or concentrations of contaminants in media.
Act of laying open; the condition of being subjected to something such as to harmful or infectious agents.
Contact with infectious agents (bacteria or viruses) in a manner that promotes transmission and increases the likelihood of disease.
Coming in contact with infectious agents (bacteria or viruses).
Coming into contact with a chemical substance.(For the three ways people can come in contact with substances, see Route of Exposure.)
contact of a person with a chemical, by breathing, touching, or swallowing.
Contact with a chemical by swallowing, by breathing, or by direct contact (such as through the skin or eyes). Exposure may be short term (acute) or long term (chronic).
A person's physical contact (visual and/or audio) with an advertising medium or message.
Contact with a contaminant through skin absorption, inhalation, or ingestion.
the act of coming into contact with a disease-causing microorganism; exposure may or may not lead to infection.
The condition of being subjected to something (e.g., infectious agents) that could have a harmful effect. A person exposed to M.tuberculosis does not necessarily become infected (see Transmission).
Coming into contact with a chemical substance by swallowing, breathing, or skin/eye contact. May be short term (acute) or long term (chronic).
Proximity and/or contact with a source of a disease agent in such a manner that effective transmission of the agent or harmful effects of the agent may occur.
Contact of a chemical, physical or biological agent with the outer boundary of an organism, for example inhalation, ingestion or contact with the skin.
being accessible or subject to an influence. When assessing the risk of a chemical, exposure means how frequently contact occurs (every day to almost never) and level of contact (very small amounts or very large amounts). Exposure is a function of the chemicalâ€™s concentration in the environment and how it is taken into the human body (breathing rate, how much is eaten)
Contact with infectious agents (e.g., bacteria, parasite, and virus) in a manner that promotes transmission and increases the likelihood of disease.
Any situation arising from work operation where an employee may ingest, inhale, absorb through the skin or eyes, or otherwise come in direct contact with a hazardous substance.
Being directly subjected to a hazardous chemical in the performance of a task through any route of entry (inhalation, ingestion, skin contact, or absorption, etc.). The Federal Hazard Communication Standard includes both accidental and possible exposures in its definition of exposure.
the does of a substance capable of causing toxic effects actually taken into the organism (in the case of a person, through ingestion, inhalation or dermally).
The amount of physical or chemical agent that reaches a target or receptor
Contact with a substance by swallowing, breathing, or touching the skin or eyes. Exposure may be short-term ( acute exposure), of intermediate duration, or long-term ( chronic exposure).
Quantity of an environmental agent impinging on a person.
The length of time and dose of chemical, biological, radiological or physical agent to which an animal or person is subjected.
The consumer's contact with an advertising medium or advertisement.
Contact made between a chemical, physical, or biological agent and the outer boundary of an organism. Exposure is quantified as the amount of an agent available at the exchange boundaries of the organism (e.g., skin, lungs, gut).
Contact with a chemical or physical agent.
The process by which the consumer comes in physical contact with a stimulus.
To come into contact with a substance. The amount of a substance someone comes into contact with is often modelled on a computer.
