Water pollutants can be classified into several categories based on their sources and characteristics. Here are some common water pollutants that you can consider for a matric class:
Agricultural activities can contribute to water pollution through the use of fertilizers, pesticides, and herbicides. These chemicals can enter water bodies through runoff, leading to contamination. Nitrate and phosphate from fertilizers are particularly concerning as they can cause eutrophication, leading to oxygen depletion in aquatic ecosystems.
Wastewater from households and urban areas can contain organic matter, pathogens, nutrients, and various pollutants. Improperly treated or untreated sewage can introduce bacteria, viruses, and parasites into water bodies, posing health risks and degrading water quality.
