Key Concepts

Environmental Chemistry

Atmospheric Chemistry

• Ozone formation/destruction
• Greenhouse gases (CO₂, CH₄, N₂O)
• Acid rain (SO₄²⁻, NOₓ)
• Particulate matter

Water Chemistry

• Dissolved oxygen
• pH and alkalinity
• Nutrients (N, P)
• Heavy metals
• Organic pollutants

Pollutant Transformations

# Example: First-order degradation
def pollutant_concentration(C0, k, t):
    """
    Calculate pollutant concentration over time.
    C0: Initial concentration
    k: First-order rate constant (1/s)
    t: Time (s)
    """
    return C0 * np.exp(-k * t)

def half_life(k):
    """Calculate half-life from rate constant."""
    return 0.693 / k
