Which factor can lead to the bad taste and odor of water due to aquatic weeds?

• A. Low pH levels
• B. Certain types of algae
• C. High levels of sedimentation
• D. Excessive light penetration

Answer: (B)

The presence of certain types of algae can indeed lead to unpleasant tastes and odors in water. Algal blooms, particularly from blue-green algae (cyanobacteria), can produce toxins and metabolic byproducts that alter the sensory properties of water. These blooms often occur in nutrient-rich environments, particularly when there is an influx of nitrogen and phosphorus from agricultural runoff or other sources. The decomposition of algal blooms can further contribute to taste and odor issues, as the decay process releases substances that may be perceived as foul or musty. Managing these algae through appropriate aquatic pest control techniques is crucial for maintaining water quality, especially in drinking water supplies and recreational bodies of water. While low pH levels, high sedimentation, and excessive light penetration can affect aquatic ecosystems, they are not directly responsible for the taste and odor issues that certain algae can create. Therefore, understanding the role of algae in water quality is essential for effective aquatic pest management practices.
