Chloronaphthalenes are a class of polycyclic aromatic hydrocarbons (PAHs) containing one or more chlorine atoms attached to the naphthalene ring structure. These compounds exhibit varying degrees of toxicity and can be found as impurities in various industrial processes, including petrochemical refining, pesticide production, and chlorination reactions. Due to their chemical stability and reactivity, chloronaphthalenes are used in a range of applications such as flame retardants, rubber additives, and pharmaceutical intermediates. However, concerns over environmental contamination and potential health risks associated with these substances have led to stricter regulations on their use and disposal. Comprehensive risk assessment and management strategies are essential for minimizing the adverse effects of chloronaphthalenes in industrial settings and protecting public health.
