In human body, chlorinated hydrocarbons accumulate in
A) Bones
B) Brain
C) Fatty tissue
D) Skin

Hint: Chlorinated hydrocarbons are compounds having the hydrogen and carbons, one of hydrogen substituted with chlorine that is why they are called chlorinated hydrocarbons.

Complete answer:
Hydrocarbons are present in a major amount in the environment.
Source
>Ingested hydrocarbons:- gasoline, mineral spirit, lamp oil, kerosene, lubricating oil, lighter fluid and motor oil.
>Volatile substances that contain hydrocarbons:- glue and propellants.
>Other common sources of hydrocarbons:- dry cleaning solution, paint, rubber cement and solvents.
>Chlorinated hydrocarbons are not water soluble.
>These hydrocarbons combine with tissue which is having fat in the animal and human body.
>When the consumption of hydrocarbons increases they have a tendency to accumulate in the fats.

Additional information:
Insecticide and pesticide are the common and mostly used hydrocarbons and show biomagnifications.
Biomagnifications are defined as the increased concentration of toxic substances in the tissue of the body.
Effects of hydrocarbons on the body: cause cancer, cause irritation in eyes, bronchial constriction, abscission and formation of secondary pollutants by combining with oxides of nitrogen.

 So, the correct answer is that in the human body, chlorinated hydrocarbons accumulate in fatty tissue.

Note:Accumulated hydrocarbons from the fatty tissue, goes to myelin sheath of neurons and connective tissue and that’s the reason for various diseases. These hydrocarbons are usually not soluble in water that is why they tend to combine with the fatty tissues in the human body or animals.
