Toxicity correct answersthe ability of a substance to cause harmful effects chemical is considered toxic correct answerswhen a small amount can be harmful Toxicity depends on three factors correct answers1. chemical structure 2. substance absorbed by body 3. body's ability to detoxify and eliminate the substance Hazard correct answersthe practical likelihood that a chemical will cause harm Some chemicals are hazardous because correct answersthe risk of fire or explosion Inhalation correct answerscommon type of exposure and occurs when you breath a substance into the lungs Skin contact correct answersSome chemicals can easily pass through the skin and enter the blood stream Eye Contact correct answersThey may be absorbed through the eye and enter the bloodstream, taken as serious incident Ingestion correct answerschemicals can be ingested if they are left on hands, clothing or beard, or accidentally contaminate foods, drinks or cigarettes dose-response relationship correct answersthe greater the AMOUNT of a substance that enters your body, the greater is the EFFECT on your body threshold level correct answerslowest concentration that might produce a harmful effect Rate of exposure correct answerscombination of dose and duration latency period correct answersthe delay between the beginning of exposure and the appearance of disease caused by that exposure Acute exposure correct answersa single exposure or a few exposures Acute effects correct answersthose which occur following acute exposures which can be delayed or immediately occur Chronic exposure correct answersrepeated exposure that occurs over months and years Chronic effects correct answersthose which occur following chronic exposures, and so are always delayed reaction occurs when correct answerschemicals combine to form a new substance, which may have properties different from the original substances and could be more hazardous interaction occurs when correct answersexposure to more than one substance results in a health effect different from the effects of either one alone Synergism correct answersa process in which two or more chemicals produce an effect that is greater than the sum of their individual effects ex: ccl4 and alcohol Potentiation correct answersoccurs when an effect of one substance is increased by exposure to a second substance which would not cause that effect by itself
