Abstract:
Polyhalogenated carbazoles (PHCZs) are a new type of organic pollutants, characterized by its environmental persistence, bioaccumulation property, and toxicity similar to dioxins. The pervasive environmental presence of PHCZs, coupled with their heterogeneous spatial distribution, has garnered increasing scientific attention. Furthermore, studies have detected PHCZs in humans and demonstrated their toxic effects. Therefore, this study aims to conduct a more in-depth investigation and analysis of the systemic toxicity of PHCZs in humans and their specific molecular mechanisms. This review delves into the toxicological effects of PHCZs on humans, categorizing them into cardiotoxicity, neurotoxicity, hepatotoxicity and endocrine disruption. It also explores their metabolic transformation in the human body, ecotoxicological effects and potential degradation strategies. The content covers analytical methods, environmental occurrence patterns, ecological impacts, degradation mechanisms and prevention and control measures. This work clarifies the specific toxicological effects of PHCZs on humans, provides new therapeutic directions for future disease treatment, and enhances the environmental risk assessment and management of PHCZs.

Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
