Write a 1,050- to 1,400-word paper free from grammar and spelling
issues.
Explain the difference between toxicokinetics and toxicodynamics.
What steps are involved in toxicokinetics?
Explain the primary routes of exposure for toxicants.
Explain the various pathways of distribution for toxicants.
Explain the four principal mechanisms in moving toxicants across the
cell membrane, or uptake.
What is involved in Phases I and II of biotransformation?
What can occur as a result of biotransformation?
Identify the environmental effect of toxicants.
Select one of the following major toxicants: benzene, carbon monoxide,
lead, chromium, mercury, asbestos, arsenic, alcohol, or formaldehyde
Discuss:
Sources of the toxicant
Physical properties of the toxicant
Routes of exposure—absorption—for the toxicant
Pathway of distribution—transport—for the toxicant
Uptake of your toxicant across the cell wall or membrane
