In human body, the chlorinated hydrocarbons keep on accumulating in:

Options

A. bones
B. brain
C. skin
D. fatty tissue

Answer

**Step-by-Step Solution:**

1. **Understanding Chlorinated Hydrocarbons**: Chlorinated hydrocarbons are organic compounds that contain chlorine atoms. They are known for their fat-soluble properties, meaning they dissolve in fats rather than in water.

2. **Properties of Chlorinated Hydrocarbons**: Since chlorinated hydrocarbons are fat-soluble, they do not dissolve in water. This characteristic is crucial in determining where they accumulate in the human body.

3. **Identifying Possible Accumulation Sites**: The question provides four options for where chlorinated hydrocarbons might accumulate: bones, brain, skin, and fatty tissues. We need to analyze each option based on the solubility of chlorinated hydrocarbons.

4. **Analyzing the Options**:
- **Bones**: Bones are primarily composed of minerals and are not fatty tissues, so they are not suitable for the accumulation of fat-soluble substances.
- **Brain**: While the brain contains some fat, it is largely composed of water and does not serve as a primary site for the accumulation of fat-soluble compounds.
- **Skin**: The skin has some fatty components, but it is not a major storage site for fat-soluble toxins.
- **Fatty Tissues**: Fatty tissues (adipose tissue) are specifically designed to store fats and fat-soluble substances. Therefore, this is the most likely site for the accumulation of chlorinated hydrocarbons.

5. **Conclusion**: Based on the analysis, chlorinated hydrocarbons accumulate in fatty tissues. Thus, the correct answer is option 4: fatty tissues.
