Toxicities of Polycyclic Aromatic Hydrocarbons for Aquatic Animals
Summary
This review examines the toxicity of polycyclic aromatic hydrocarbons (PAHs) in aquatic animals, including their effects on hormones, tissue damage, and cancer risk. Researchers highlight the growing concern about microplastics acting as carriers for these harmful chemicals in water environments. The study emphasizes the need to address PAH pollution in aquatic ecosystems, particularly as microplastics may increase organisms' exposure to these toxic compounds.
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that are widely distributed in the air, water, and soil. Recently, the amount of PAHs derived from fuels and from incomplete combustion processes is increasing. In the aquatic environment, oil spills directly cause PAH pollution and affect marine organisms. Oil spills correlate very well with the major shipping routes. Furthermore, accidental oil spills can seriously impact the marine environment toxicologically. Here, we describe PAH toxicities and related bioaccumulation properties in aquatic animals, including invertebrates. Recent studies have revealed the toxicity of PAHs, including endocrine disruption and tissue-specific toxicity, although researchers have mainly focused on the carcinogenic toxicity of PAHs. We summarize the toxicity of PAHs regarding these aspects. Additionally, the bioaccumulation properties of PAHs for organisms, including invertebrates, are important factors when considering PAH toxicity. In this review, we describe the bioaccumulation properties of PAHs in aquatic animals. Recently, microplastics have been the most concerning environmental problem in the aquatic ecosystem, and the vector effect of microplastics for lipophilic compounds is an emerging environmental issue. Here, we describe the correlation between PAHs and microplastics. Thus, we concluded that PAHs have a toxicity for aquatic animals, indicating that we should emphasize the prevention of aquatic PAH pollution.

A review of human and animals exposure to polycyclic aromatic hydrocarbons: Health risk and adverse effects, photo-induced toxicity and regulating effect of microplastics
This review examines the health risks of polycyclic aromatic hydrocarbons (PAHs), toxic chemicals from burning fossil fuels, and how microplastics can change their behavior in the environment. Microplastics absorb PAHs on their surface, potentially carrying these cancer-causing chemicals into organisms that ingest the contaminated particles. The combined toxicity of PAHs attached to microplastics may be greater than either pollutant alone, increasing risks to both wildlife and human health.
Evaluation of Polyciclic Aromatic Hydrocarbons in Water and Microplastics
Researchers measured five cancer-linked PAH compounds in water samples and found that microplastics can bind these chemicals, potentially concentrating them. This suggests microplastics may act as carriers of carcinogenic compounds in drinking water and aquatic environments.
Polycyclic Aromatic Aydrocarbons (PAHs) Pollution Approaches in Aquatic Ecosystems: Perils and Remedies Using Green Technologies
This review covers the sources, health risks, and cleanup methods for polycyclic aromatic hydrocarbons (PAHs), persistent chemical pollutants found throughout aquatic ecosystems. Researchers found that green technologies, including biological and plant-based approaches, show promise for removing PAHs from contaminated water. The study highlights how these pollutants, like microplastics, can carry additional toxic compounds and move through aquatic food chains.
Sorption, Extraction, and Characterization of Polycyclic Aromatic Hydrocarbons in Environmentally Weathered Microplastics, Particulate Organic Matter, Sediment, and Fish Species in the Lavaca-Matagorda Bay System
Researchers studied how microplastics carry cancer-causing chemicals called polycyclic aromatic hydrocarbons (PAHs) in the Lavaca-Matagorda Bay system in Texas. They found PAHs attached to microplastics, sediment, and in the digestive systems of three commercially important fish species. This shows that microplastics can act as vehicles for toxic chemicals in coastal waters, potentially affecting the safety of fish that people eat.
Bioaccumulation of polycyclic aromatic hydrocarbons and their human health risks depend on the characteristics of microplastics in marine organisms of Sanggou Bay, China
This study found that the type and characteristics of microplastics present in marine organisms from Sanggou Bay, China, influenced how much of the harmful chemical pollutant PAH (polycyclic aromatic hydrocarbons) accumulated in their tissues. Smaller, more degraded microplastics carried more PAHs into organisms, raising the human health risk from eating contaminated seafood and highlighting that microplastics act as vehicles for other toxic chemicals.
