Research progress of persistent organic pollutants in water: classification, sources, potential risks, and treatment approaches

The occurrence of persistent organic pollutants (POPs) in almost every sphere of life and their notorious effects have been a global concern for quite a few decades, regardless of the fact that notable conventions have banned the standard POPs. Control measures and numerous technologies are being researched, but still exhibits challenges to completely curb these chemicals' destructive effects. The negative impacts of the POPs in terms of environmental and human health are a growing concern. In recent years, studies have proven that the list of POPs keeps increasing, and their concentrations levels are widely varied region wise. The current review presents sources and classification of POPs. Furthermore, the deleterious consequences due to POPs on environment and human health have been illustrated. A few potential methodologies that can be implemented to control the hazardous effects of POPs have been discussed.
