Abstract
Students calculate the amount of pesticide residue in various foods for two pesticides and determine if these levels are safe for human consumption.
Objectives
Students will be able to:
- Calculate the dose of a pesticide using food intake levels and pesticide residue concentrations
- Evaluate the safety of food pesticide residue food intake levels and pesticide residue concentrations
