• Effects of pollution on human health and ecosystems.

• Strategies for pollution control and prevention.

2. Atmospheric Chemistry

• Composition and layers of the Earth's atmosphere.

• Greenhouse effect and global warming.

• Ozone layer depletion and its consequences.

• Acid rain formation and its chemistry.

3. Water Chemistry

• Properties of water, its importance, and unique characteristics.

• Sources of water pollution: industrial, agricultural, and domestic.

• Water treatment processes: coagulation, filtration, disinfection, etc.

• Biochemical oxygen demand (BOD) and chemical oxygen demand (COD).

4. Soil Chemistry

• Soil components and their roles in supporting life.

• Soil pollution: contaminants, sources, and effects on plants and animals.

• Soil fertility and nutrient management.

• Remediation techniques for polluted soils.

5. Environmental Monitoring

• Analytical methods for assessing pollution levels.

• Use of instruments for measuring air quality, water quality, etc.

• Importance of environmental standards and regulations.

• Data interpretation and analysis for decision-making.

6. Green Chemistry

• Principles of green chemistry for sustainable chemical processes.

• Reduction of hazardous substances in chemical reactions.

Important Equations from Environmental Chemistry

1. Chemical Oxygen Demand (COD): $\text{COD} = \frac{\text{Amount of Oxygen required to oxidize organic matter}}{\text{Volume of sample}}$

2. Biochemical Oxygen Demand (BOD): $\text{BOD} = \frac{\text{Initial Dissolved Oxygen} - \text{Final Dissolved Oxygen}}{\text{Volume of sample}}$

3. Water Hardness: $\text{Hardness}=\frac{\text{Equivalents of CaCO}_3}{\text{Volume of water sample}}$

4. Half-life (t½) of a Radioactive Substance: $N_t = N_0 \left( \frac{1}{2} \right)^{\frac{t}{t_{1/2}}}$

5. Rate of Reaction: $\text{Rate} = \frac{\Delta [\text{Reactant}]}{\Delta t}$

6. Gibbs Free Energy Change (ΔG): $\Delta G = \Delta H - T \Delta S$

7. Nernst Equation: $E = E^\circ - \frac{0.0591}{n} \log_{10} \frac{[\text{Reductant}]}{[\text{Oxidant}]}$

8. Ideal Gas Law: PV=nRT

9. Henry's Law: $C = k \times P$

10. Beer-Lambert Law: $A = \varepsilon \cdot l \cdot c$
