Document Summary
Need to understand this weeks concept, because on test u will get a new graph, and. Need to apply what you learned from class. Organism: biomagnification building up over time, across the levels in a food chain (in many. Organisms in a food chain: generally, high-molecular-weight chemicals are, more lipophilic and more persistent, less volatile and less water-soluble, persistence in environment, quantified as a half-life in air, water, or soil, affected by environmental conditions. Important to know of the person: age, general health, genetic makeup: exposure, contact with the human envelope, routes of exposure. Ingested (often greatest source of chemical exposure, 85%) The dose-response relationship: quantitative relationship between dose and effect (response, often summarized in graph, dose on x-axis; response of y-axis, graded response as a function of dose, acute toxicity tests are used. Answer: more toxic b, more safe- a.
