environmental-chemistry

## What I do - Study chemical processes in natural environments - Analyze pollutants and their transformations - Investigate atmospheric chemistry - Research water and soil chemistry - Assess environmental contamination - Develop remediation strategies ## When to use me - When studying environmental pollution - When analyzing water quality - When investigating atmospheric chemistry - When assessing contaminated sites - When developing remediation strategies - When studying biogeochemical cycles ## 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 ```python # 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 ``` ### Biogeochemical Cycles - Carbon cycle - Nitrogen cycle - Phosphorus cycle - Sulfur cycle - Water cycle ### Remediation Technologies - Bioremediation - Phytoremediation - Soil washing - Air stripping - Adsorption (activated carbon) - Advanced oxidation processes
