Study Notes
What are Harmful Algal Blooms (HABs)?
- Excessive growth of algae in aquatic environments, leading to negative impacts on ecosystem, human health, and economy
- Algae are photosynthetic organisms that play a crucial role in food chain and oxygen production
Formation of HABs
- Occur under certain conditions: increased nutrient levels and warm water temperatures
- Some algae species multiply rapidly, forming dense colonies known as blooms
Characteristics of HABs
- Water discoloration: green, red, or brown hues due to high concentrations of algae
- Blocking sunlight, reducing light availability for photosynthesis and affecting growth and survival of other organisms
Impacts of HABs
- Negative impacts on aquatic organisms, including fish, shellfish, and marine mammals
- Toxins released by some algae species can harm aquatic life and humans
- Human consumption of contaminated organisms can lead to food poisoning and health issues
Factors Influencing HABs
- Nutrient pollution
- Climate change
- Human activities
