Toxicology and Epidemiology Quiz

The process by which a substance enters the body and reaches the bloodstream.

Harmful effects occurring at the point of contact with a substance, such as burns or irritation.

Harmful effects occurring in a part of the body distant from the point of contact, such as organ damage.

The organ or tissue that is primarily affected by a substance.

Immediate and obvious responses to exposure to a substance, usually reversible.

Effects that appear a long time after exposure and can be irreversible.

The time period between exposure to a substance and the first symptoms of disease.

A device used to control airflow in ducts of different sizes by balancing the air pressure.

The study of how air and fluids flow, particularly about the transition between laminar and turbulent flows.

Airborne particulate matter is collected by a pump with an MCE filter, allowing for analysis of the overall particulate matter.

Airborne particulate matter specifically smaller than 4 microns is collected by a pump with a cyclone, focusing on respirable particles.

A method of air sampling where the velocity of the air in the sampling nozzle matches the velocity of the air stream.

A psychological condition often mistaken for a physical ailment, triggered by stress and often related to indoor air quality (IAQ).

An air pollution control device that captures dust and particulate matter less than 0.25 microns.

A technique used to collect particles in a moving stream by charging particles with a positive or negative charge, then collecting them on oppositely charged plates.

A condition where individuals experience sensitivity or intolerance to extremely low levels of common chemicals.

A device used to collect airborne particulate matter by forcing air through a series of stages.

A sampling method used to collect gases and vapors by adsorbing them onto activated charcoal.

A device that measures the concentration of airborne particles in real-time using ultraviolet light to ionize molecules.

A device used to measure particle concentrations in the air, providing real-time results.

A device used to measure concentrations of semi-volatile compounds in air, requiring laboratory analysis.

A device used to collect and measure a variety of airborne contaminants, requiring laboratory analysis.

The minimum amount of a substance that can be detected by an analytical method.

A device used to measure carbon monoxide (CO) concentrations in the air.

An instrument used to measure multiple parameters, often used in occupational settings.

A process used to ensure the proper handling and tracking of samples throughout their lifecycle.

A symbiotic relationship where both species benefit.

A symbiotic relationship where one species benefits and the other is unaffected.

A symbiotic relationship where one species (the parasite) benefits while the other species (the host) is harmed.

A bacteria commonly found in seawater, often causing gastroenteritis after consuming undercooked seafood.

A heat treatment process that hardens metal by absorbing carbon monoxide (CO) at high temperatures.

A plan designed to protect laboratory workers from hazardous chemicals.

The act of monitoring or measuring the exposure of workers to toxic substances or harmful physical agents.

The measurement of a toxic substance or harmful physical agent in a worker's body, such as blood, urine, or breath.

The concentration of a substance in a solution, measured in moles per liter (mol/L).

A measure of the amount of a substance, equivalent to its molecular weight in grams.

A type of protein made by certain white blood cells in response to a foreign substance (antigen).

Is a lung disease caused by inhalation of FeO or another metallic particle.

The effects of exposure to a substance depend on factors like the dose, rate of exposure, substance's physical state, temperature, absorption site, diet, and overall health.

Legal exposure limits to airborne substances in the US established by OSHA, often based on NIOSH TLVs.

A sub-microscopic infectious agent incapable of growing or reproducing outside a host cell, containing nucleic acid, capsid, envelope, but NOT a cell wall.
