a flavorants odor threshold is usually written as a concentration in air or water. often, this concentration has units of parts per billion. in this case, parts per billion, or ppb, is a measurement of the number of flavorant particles in every billion particles of air or water. for example, if a flavorants odor threshold is 2 ppb in water, this means that a human can detect the flavorant only if there are two or more flavorant particles per billion particles of water. imagine a flavorant whose odor threshold is 15 ppb in water. at which concentrations in water would a person likely be able to detect the flavorant? select all that apply. 5 ppb 15 ppb 100 ppb

Answer

Answer:

B. 15 ppb, C. 100 ppb

Explanation:

Step1: Understand odor - threshold concept

The odor - threshold is the minimum concentration at which a human can detect a flavorant.

Step2: Analyze given threshold

The flavorant has an odor - threshold of 15 ppb in water. A person can detect the flavorant at concentrations equal to or greater than this threshold.

Step3: Evaluate options

5 ppb is less than 15 ppb, so it cannot be detected. 15 ppb (equal to the threshold) and 100 ppb (greater than the threshold) can be detected.
