To remove which pollutants, enzymatic filters are used?

Options

A. Hydrocarbons
B. Lead
C. Nitrogen pollutants
D. Chloride pollutants

Answer

To determine which pollutants enzymatic filters are used to remove, we can analyze the options provided: hydrocarbons, lead, nitrogen pollutants, and chloride pollutants.

### Step-by-Step Solution:

1. **Understanding Enzymatic Filters**: Enzymatic filters utilize specific enzymes to break down pollutants into less harmful substances. They are designed to target organic compounds.

2. **Identifying the Pollutants**:
- **Hydrocarbons**: These are organic compounds made up of hydrogen and carbon, commonly found in fuels and oils.
- **Lead**: This is a heavy metal and does not typically get removed by enzymatic processes.
- **Nitrogen Pollutants**: These include compounds like nitrates and ammonia, which may require different treatment methods.
- **Chloride Pollutants**: These are inorganic and typically not targeted by enzymatic filters.

3. **Analyzing the Most Suitable Option**: Among the given options, hydrocarbons are organic compounds that can be effectively treated using enzymatic filters. The enzymes can break down these compounds, allowing for their removal.

4. **Conclusion**: Based on the analysis, enzymatic filters are specifically used to remove hydrocarbons from the environment.

### Final Answer:
Enzymatic filters are used to remove **hydrocarbons**.
