Answer:
Emerging water pollutants are elements or their acids, which are not generally found in water sources and hence not much concern was given on them by scientific community. But with observed increasing ecological disturbance and improved scientific methods, they have been analyzed for their origin and mechanism of health impacts. These emergent water pollutants can make changes in human behavior, landscape, water resources, and demography, due to developing technologies, microbial adaptation, climate change, increased travel, and so on. This category of pollutants includes pharmaceuticals, algal toxins, microorganisms, and several other chemicals. To prevent these contaminants from the water, it is required to understand their features, generation, transportation, side effects on human health and environments, analysis approaches, and resolving techniques.
