๐ In Situ Water Quality Monitoring for the Assessment of Algae and Harmful Substances with Consideration of Uncertainties
๐ 1. Introduction to In Situ Water Quality Monitoring In situ water quality monitoring refers to the real-time, on-site measurement of chemical, physical, and biological parameters within natural water bodies ๐ฟ. This method eliminates the delays, distortions, and contamination risks associated with laboratory sampling. Through compact sensors and autonomous devices, researchers and environmental agencies can detect changes in water composition with remarkable immediacy ⏱️. ๐งช 2. Monitoring of Algae and Harmful Substances ๐ข 2.1 Algal Detection Excessive algae—especially harmful algal blooms (HABs) —pose threats to ecosystems, water supply, and aquatic life. In situ sensors, such as fluorometers, identify: Chlorophyll-a concentrations ๐ฑ Phycocyanin for cyanobacteria ๐ Turbidity shifts indicating bloom proliferation These tools help forecast bloom events and implement mitigation strategies before they escalate. ☣️ 2.2 Detection of Harmful Substances Water...
