Polychlorinated Naphthalenes (PCNs)

Polychlorinated naphthalenes (PCNs) are a class of persistent organic pollutants (POPs) that have sparked broad concern due to their extensive dispersion, long-term environmental persistence, and potential harm to human health and ecosystems. PCNs are produced unintentionally via various industrial processes. They are polychlorinated aromatic compounds with a strong resilience to degradation, allowing for long-distance transport across air, water, and biota. As a rapidly industrializing country, India confronts difficulties in limiting the flow of hazardous chemicals into the environment. PCNs have been found in a variety of environmental compartments around the country as an accidental result of some industrial activities. Waste incineration, heat processes, chemical manufacture, and accidental emissions from metal processing companies are among the sources of PCNs in India. Thus, this chapter presents a thorough examination of the origins, distribution, environmental destiny, toxicity, and regulatory measures connected with PCNs both internationally and in India.
