Flashcards
Eutrophication
Eutrophication
The process of a water body becoming enriched with nutrients, often from excessive amounts of fertilizers or sewage, leading to excessive plant growth and depletion of oxygen.
Biochemical Oxygen Demand (BOD)
Biochemical Oxygen Demand (BOD)
The amount of dissolved oxygen needed by microorganisms to decompose organic matter in a water sample.
Photochemical Smog
Photochemical Smog
A type of air pollution mainly caused by nitrogen oxides (NOx) reacting with sunlight. It results in a hazy brown smog that can affect air quality and human health.

Study Notes
Environmental Concepts
- Eutrophication: Excessive nutrient supply in water bodies, leading to an overgrowth of algae and depleting oxygen, harming aquatic life.
- Biochemical Oxygen Demand (BOD): Amount of oxygen consumed by microorganisms to decompose organic matter in water, indicating water quality.
- Photochemical Smog: Air pollution formed when sunlight reacts with nitrogen oxides, volatile organic compounds, and other pollutants, mainly consisting of ozone, particulate matter, and nitrogen dioxide.
- Deforestation: Clearing of forests, generally decreasing biodiversity and carbon sequestration.
- Alpha Diversity: Measure of species diversity within a specific ecosystem or habitat, referring to the variety of species present in a particular area.
