ToxicologyAlcohol Testing for Alcohol Role of Toxicologist

Row 1, Col 1 detects and identifies drugs and poisons in body fluids, tissues, and organs What is a forensic toxicologist?

1,2 the transformation of substances in the body in order to facilitate elimination from the body What is metabolism?

1,3 Common field test used to Detect the use of alcohol What is the breathalyzer?

1,4 For a living person, drugs or poisons would be detected by collection of these two samples. What is blood and urine?

2,1 the most heavily abused drug in the U.S. What is alcohol?

2,2 The three basic steps in the metabolism of alcohol. What are absorption, distribution, and elimination?

2,3 Directly proportional to blood alcohol concentration What is the amount of alcohol exhaled in breath?

2,4 For cases in which a drug or poison has been in a person’s system for a long period of time, this sample is collected and analyzed What is hair?

3,1 The administration of a breathalyzer test or collection of blood for analysis does not violate these rights What are 4 th and 5 th amendment rights?

3,2 Two processes in which alcohol Is eliminated from the body What are oxidation and excretion?

3,3 Blood alcohol concentration used as a legal measure of drunk driving in the U.S. What is 0.08?

3,4 Two factors which influence drug-induced behavior. What is age, tolerance of the user, physical condition of the user, and the interaction of multiple drugs?

4,1 tests that definitively confirm the identity of a poison or drug What are confirmation tests?

4,2 Two factors that affect the absorption of alcohol in the body What are the rate of consumption, alcohol content, the amount consumed, and food present in stomach?

4,3 Type of container used to store blood samples for the purpose of measuring alcohol concentration What is airtight?

4,4 Two challenges that toxicologists Face in detecting drugs What is the fact that drugs are found in very small amounts and that drugs are often metabolized to other substances in the body?

5,1 two common non-drug poisons detected by toxicologsists What are carbon monoxide, arsenic, lead, mercury, etc.?

5,2 Where oxidation of alcohol occurs in the body. What is the liver?

5,3 Two substances that must be added to blood samples when collected for measuring alcohol concentration What are anti-coagulants and preservatives?

5,4 Once a drug or poison is detected, the toxicologist faces this challenge. What is determining the toxicity of the drug or poison?
