Which statement best describes the persistence and biological magnification of organophosphates relative to chlorinated hydrocarbons? 

A)  Organophosphates are less persistent and more biologically magnified. 
B)  Organophosphates are more persistent and more biologically magnified. 
C)  Organophosphates are more persistent and less biologically magnified. 
D)  Organophosphates are less persistent and less biologically magnified.

Biological Magnification

The increasing concentration of toxic substances within each successive link in the food chain.

Organophosphates

A group of chemical compounds used as insecticides, which can be toxic to animals and humans if exposure occurs.

Chlorinated Hydrocarbons

Organic compounds containing chlorine, often used in industrial applications, but can be environmental pollutants.

  • Attain insight into the categorization and types of pesticides, comprising chlorinated hydrocarbons, carbamates, pyrethroids, and organophosphates.
  • Comprehend the environmental impact of pesticides, such as persistence, biological magnification, and toxicity to non-target species.

Final Answer :
D
Explanation :
Organophosphates generally break down more quickly in the environment than chlorinated hydrocarbons, making them less persistent. Additionally, because they degrade faster, they are less likely to accumulate in the tissues of organisms, leading to lower biological magnification.
