ClearA 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.
Microplastics and associated polycyclic aromatic hydrocarbons in surface water and sediment of the Bay of Bengal coastal area, India: sources, pathway and ecological risk
Researchers surveyed microplastic contamination in surface water and sediment along two Bay of Bengal coastal beaches in India and found microplastics present at both sites. They also detected polycyclic aromatic hydrocarbons, a group of harmful chemicals, adsorbed onto the microplastic surfaces at concentrations that varied by particle shape. The study highlights that microplastics in coastal waters act as carriers for toxic organic pollutants, potentially increasing ecological risks in the marine environment.
Research Progress on The Adsorption and Their Mechanisms of Polycyclic Aromatic Hydrocarbons in Soil by Microplastics
This review examines how microplastic characteristics including polymer type, particle size, density, and aging state influence their adsorption of polycyclic aromatic hydrocarbons (PAHs) in soil, along with how environmental factors such as pH and organic matter modify this interaction. The authors provide a theoretical framework for understanding the combined pollution risk of microplastics and PAHs in terrestrial ecosystems.
Interactions of microplastics with organic, inorganic and bio-pollutants and the ecotoxicological effects on terrestrial and aquatic organisms
This review systematically examines how microplastics interact with organic pollutants, heavy metals, and biological contaminants in the environment.

The study highlights the risks these interactions pose to both ecosystem health and human well-being.
Microplastics as a Modifier of Polycyclic Aromatic Hydrocarbon (PAH) Toxicity: A Review on Context-Dependent Effects Across Organisms
This review of 45 studies found that tiny plastic particles (microplastics) don't just add to the harm caused by toxic chemicals called PAHs—they can either make these chemicals more or less dangerous depending on the situation. The plastic pieces can either help chemicals get absorbed more easily into living things or trap the chemicals and reduce exposure. Since microplastics and these toxic chemicals are found together in our environment, this research shows we need better ways to understand how pollution mixtures affect human and environmental health.

Cancer may be induced by microplastics-sorbed polycyclic aromatic hydrocarbons?
This review explores the potential link between microplastics that have absorbed polycyclic aromatic hydrocarbons and cancer risk in humans.

The study indicates that the combination of microplastics and adsorbed pollutants may pose a heightened concern for human health.

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.
Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants
