They identified strategies ranging from adjusting cooking methods and temperatures to using adsorbent filters and modified packaging to minimize human dietary exposure.
Microplastics and associated PAHs in surface water from the Feilaixia Reservoir in the Beijiang River, China
Microplastics collected from surface water in the Feilaixia Reservoir in China were found to be associated with polycyclic aromatic hydrocarbons (PAHs), with higher PAH concentrations on microplastics than in the surrounding water. The results suggest microplastics can concentrate and transport PAHs in reservoir systems, posing risks to aquatic life and potentially to drinking water.
Microbes and Microbial Strategies in Carcinogenic Polycyclic Aromatic Hydrocarbons Remediation: A Systematic Review
This systematic review catalogued microbial strategies for remediating carcinogenic polycyclic aromatic hydrocarbons (PAHs) from the environment, including enzymatic degradation, biofilm formation, and genetically engineered microorganisms. The research is relevant to microplastics because PAHs frequently adsorb onto microplastic surfaces, and microbial degradation of both the plastics and their associated pollutants is an active area of investigation.
Current innovative approaches in reducing polycyclic aromatic hydrocarbons (PAHs) in processed meat and meat products
This review examines how cancer-causing polycyclic aromatic hydrocarbons (PAHs) form in processed meats during cooking methods like grilling, smoking, and frying. While not directly about microplastics, PAHs are relevant because they are among the harmful chemicals that can attach to microplastic surfaces in the environment. The paper discusses various strategies to reduce PAH formation in food, which matters for overall exposure to carcinogens through the diet.
Sources, Occurrences, and Risks of Polycyclic Aromatic Hydro-Carbons (PAHs) in Bangladesh: A Review of Current Status
This review examines levels of polycyclic aromatic hydrocarbons (PAHs), toxic chemicals from burning fossil fuels, across water, soil, air, and seafood in Bangladesh, finding concentrations higher than in most other countries. Health assessments revealed both cancer and non-cancer risks to residents from eating contaminated seafood. While focused on PAHs rather than microplastics directly, the findings are relevant because microplastics can absorb and concentrate these same cancer-causing chemicals, potentially worsening human exposure.
Voyaging of halogenated polycyclic aromatic hydrocarbons, an emerging group of pollutants, on micro-mesoplastics in the marine environment.
Researchers detected 61 of 75 target halogenated polycyclic aromatic hydrocarbons in micro-mesoplastics collected from coastal environments in Sri Lanka and Japan, finding that plastic surfaces accumulate these emerging pollutants at concentrations far exceeding surrounding sediments and that chlorinated PAHs dominated over brominated forms at both sites.

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 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.
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.
Interactions between polyaromatic hydrocarbons and microplastics: Environmental mechanisms and ecotoxicological impacts
This review examines how microplastics interact with polycyclic aromatic hydrocarbons, a class of toxic organic pollutants found throughout the environment. Evidence indicates that microplastics can adsorb these pollutants and alter their availability and toxicity to living organisms, with effects depending on plastic type, pollutant properties, and environmental conditions. The study identifies critical gaps in long-term exposure research and calls for standardized testing methods to better assess these combined risks.
PM2.5-bound polycyclic aromatic hydrocarbons (PAHs): quantification and source prediction studies in the ambient air of automobile workshop using the molecular diagnostic ratio
Researchers measured cancer-causing polycyclic aromatic hydrocarbons (PAHs) bound to fine airborne particles near automobile workshops in Nigeria, finding concentrations well above safe levels in both dry and rainy seasons. Gasoline and diesel combustion were the main sources of these toxic compounds. While not directly about microplastics, PAHs are among the harmful chemicals that can stick to microplastic surfaces, and this study shows how airborne pollution creates chemical contaminants that microplastics can transport into water, soil, and the body.
