Waste Management and Pollution Questions
What are some of the most promising bioremediation technologies for removing EDCs from the environment?
-
Phytoremediation
-
Mycoremediation
-
Bioaugmentation
-
Bioventing
Correct answer
Explanation
There are a number of promising bioremediation technologies for removing EDCs from the environment. Phytoremediation is the use of plants to remove EDCs from the soil and water. Mycoremediation is the use of fungi to remove EDCs from the soil and water. Bioaugmentation is the addition of microorganisms to the environment to enhance the biodegradation of EDCs. Bioventing is the use of air to stimulate the biodegradation of EDCs in the soil.

Which of the following is NOT a characteristic of hazardous waste?
-
Ignitability
-
Corrosivity
-
Reactivity
-
Biodegradability
D
Correct answer
Explanation
Biodegradability is not a characteristic of hazardous waste, as it refers to the ability of a substance to be broken down by natural processes.
Which of the following is a common method for treating hazardous waste?
-
Incineration
-
Landfilling
