Pharmaceutical wastewater as Emerging Contaminants (EC): Treatment technologies, impact on environment and human health

A wide range of unregulated chemicals of synthetic origin or derived from natural sources, which may be a contender for future regulations are called Emerging Contaminants (ECs). The concentration of ECs ranges from ng/L to μg/L, which is comparatively smaller as compared to other pollutants present in water and wastewater. Even though the environmental concentration is low, ECs still possess a great threat to the humans and ecosystem. These compounds are being widely studied due to their potential health effects, pervasive nature, and difficult degradation through conventional techniques. Pharmaceutical active compounds (PhACs) or pharmaceutical contaminants (PCs) are one of the major groups of ECs which can…
