Sample interview questions: Can you explain the concept of eutrophication and its impact on water quality?
Sample answer:
Concept of Eutrophication
Eutrophication is the process by which water bodies become enriched with nutrients, leading to increased growth of algae and other aquatic plants. It is a natural process that occurs over time as nutrients accumulate in water bodies from sources such as agricultural runoff, wastewater discharge, and atmospheric deposition. However, human activities can accelerate eutrophication by increasing the input of nutrients into water systems.
Impact on Water Quality
Eutrophication can have a significant impact on water quality. Excessive algal growth can lead to:
- Reduced water clarity: Algal blooms can block sunlight from reaching submerged aquatic vegetation, reducing photosynthesis and the overall productivity of the ecosystem.
- Dissolved oxygen depletion: As algae decompose, they consume dissolved oxygen, creating hypoxic conditions that can harm fish and other aquatic life.
- Increased toxicity: Some algae species produce toxins that can accumulate in fish and shellfish, posing a health risk to h… Read full answer
