Summary
Polychlorinated naphthalenes (PCNs) are persistent environmental pollutants found globally. This review covers recent data on PCN pollution, chemistry, sources, and toxicity, highlighting their impact on biota and potential for aryl hydrocarbon receptor-mediated effects.
Area of Science:
- Environmental Chemistry
- Toxicology
- Ecotoxicology
Background:
- Polychlorinated naphthalenes (PCNs) are a group of up to 75 congeners.
- PCNs are widespread global environmental pollutants that bioaccumulate.
- As planar compounds, PCNs can induce toxicity via the aryl hydrocarbon (Ah) receptor.
Purpose of the Study:
- To review recent data on polychlorinated naphthalenes (PCNs).
- To cover environmental pollution, chemistry, analysis, sources, formation, persistence, toxicity, and behavior of PCNs.
Main Methods:
- Literature review of recent data.
- Synthesis of information on PCN properties and environmental fate.
Main Results:
- PCNs originate from technical formulations and industrial processes.
- PCNs exhibit persistence and bioaccumulation in environmental matrices.
- PCNs contribute to dioxin-like toxic responses through Ah receptor activation.
Conclusions:
- PCNs represent a significant environmental challenge due to their persistence and toxicity.
- Understanding PCN behavior is crucial for risk assessment and management.
- Further research is needed to fully elucidate the impact of PCNs on ecosystems and human health.
