This set of Environmental Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Measurement of Bioaccumulation”.
1. Bioaccumulation of organic substances follows the simple empirical model of partition.
a) True
b) False
View Answer
Explanation: Simple empirical model of partition is followed between the aqueous medium and the organism which leads to bioaccumulation of organic substances.
2. In partial hypothesis, the entire organism is considered as a single compartment.
a) True
b) False
View Answer
Explanation: In partial hypothesis, it is based on two compartment systems where the entire organism is considered as a single compartment.
3. Which of the following factors is responsible for chemical accumulation in the organism?
a) Nutrient load
b) Temperature
c) Lipophilicity
d) pH
View Answer
Explanation: Chemical accumulation in the organism depends upon the lipid content and lipophilicity of an organism, whereas, the toxicant accumulation depends upon certain environmental conditions like Nutrient load, Temperature, pH.
4. Exposure of standard test batteries to a known concentration of toxicant is not an acceptable method to test bio-accumulation.
a) True
b) False
View Answer
Explanation: Bio-accumulation can be measured by exposure of standard test batteries to a known concentration of toxicant, and it is the quickest method.
5. Which of the following is not used as a standard test battery for measuring bio-accumulation?
a) Algae
b) Zooplanktons
c) Fish
d) Birds
View Answer
Explanation: Algae, Zooplanktons, Fish and animals like mice and dogs are used as standard test batteries for measuring bio-accumulation, whereas, birds are not used as test batteries.
