Toxicology Exam quiz and answers
well graded A+
Contaminant - ANS✅✅undesirable solid, liquid, or gas occurring as a result of human activity
without causing adverse effects
Pollutant - ANS✅✅undesirable solid, liquid, or gas occurring as a result of human activity causing
adverse effects
Toxicant - ANS✅✅substance causing injury to living organisms as a result of physiochemical
interaction
Toxic - ANS✅✅able to cause injury to living organisms as a result of physiochemical interactions
nickel, cadmium, zinc, lead, copper are all positively charged cations and readily complex w/ other
ligands in aquatic systems - ANS✅✅5 Metals
Organics - ANS✅✅carbon based
often in herbicides and insecticides
Stressor - ANS✅✅physical, chemical, and biological factors causing adverse response on
ecosystem
Acute Exposure - ANS✅✅exposure of test organisms is continuous and lasts 4 days or less
often in high concentrations
Chronic Exposure - ANS✅✅exposure of test organisms is continuous and great than 4 days
often in low concentrations
Ecology - ANS✅✅the study of interactions between living organisms and all factors in the
environment
determines distribution of living organisms
, Toxicity - ANS✅✅capacity to cause injury to an organisms w/ reference to the quality of substance
administered or absorbed and the way in which the substance is administered
Toxicology - ANS✅✅study of adverse effects of chemicals on living systems
Environmental Toxicology - ANS✅✅study of adverse effects of environmental contaminants on
humans
Ecotoxicology - ANS✅✅the study of harmful effects of chemicals upon ecosystems, to include
effects upon individuals as well as consequent effects at the levels of population and beyond
molecules -> cells -> species -> population -> community -> ecosystem-> biosphere -
ANS✅✅Biological Organization
temperature
suspended and bedded solids
light
habitat
chemicals
hardness - ANS✅✅6 Physical Stressors
predation
parasitism
disease
genetics
natural toxins - ANS✅✅5 Biological Stressors
Fate - ANS✅✅how long contaminants persist, where do they go, and what is the concentration
Transport - ANS✅✅movement of contaminants fora distance within and between compartments
Adsorption - ANS✅✅adheres to outside of organism
