Potassium (K+)

Potassium (K⁺) is an essential nutrient for plant growth and overall biological function, playing a vital role in various physiological processes. In water quality monitoring, potassium levels are monitored to assess the nutrient content and potential impacts on aquatic ecosystems. Elevated potassium concentrations can result from agricultural runoff, wastewater discharge, or natural weathering of rocks and minerals.

While potassium is generally not considered a primary pollutant, excessive levels can contribute to nutrient imbalances, algae blooms, and ecological disturbances in aquatic environments. Monitoring potassium levels helps in understanding nutrient dynamics, managing water quality, and preserving the health and balance of aquatic ecosystems.
