ClearAssessment of cancer risk of microplastics enriched with polycyclic aromatic hydrocarbons
Researchers assessed the cancer risk of microplastics originating from e-waste that had adsorbed carcinogenic polycyclic aromatic hydrocarbons (PAHs). The study found that microplastics effectively captured PAHs through adsorption and estimated the probable cancer risk from human ingestion of PAH-enriched microplastics, suggesting this exposure pathway warrants further health risk evaluation.
Microplastics-sorbed phenanthrene and its derivatives are highly bioaccessible and may induce human cancer risks
Researchers studied how microplastics sorb phenanthrene and its derivatives, then measured the bioaccessibility and potential cancer risk of these contaminant-laden particles. The study found that microplastic-sorbed polycyclic aromatic hydrocarbons were highly bioaccessible during simulated digestion, suggesting they may pose meaningful human health risks when ingested.
Comment on “cancer may be induced by microplastics-sorbed polycyclic aromatic hydrocarbons?”

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.
Micro(nano)plastics pollution and human health: How plastics can induce carcinogenesis to humans?
This review examines how microplastics and nanoplastics enter the human body through food, water, and air, and how they may contribute to cancer development. Common plastic types like polystyrene and PVC, along with toxic chemicals they carry such as PAHs and PCBs, have been linked to DNA damage, oxidative stress, and inflammation, all of which can promote cancer. The paper highlights that while the evidence is growing, more research is needed to understand the full cancer risk from chronic microplastic exposure.
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.
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.
Toxicities of Polycyclic Aromatic Hydrocarbons for Aquatic Animals
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.
Microplastics and cancer
This review examines evidence linking microplastics to cancer risk, noting that microplastics have been detected at higher concentrations in human tumor tissues than adjacent healthy tissue, and that they can act as vectors for carcinogens while inducing oxidative stress, inflammation, and genotoxicity.
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.
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.

From Exposure to Oncogenesis: the Role of Microplastics and Associated Pollutants in Cancer - a Literature Review
This literature review examined the growing evidence linking microplastic exposure to cancer development. Microplastics have been found in human lung, liver, and colon tissue, and research suggests they may promote cancer through chronic inflammation, oxidative stress, and by carrying known carcinogens like heavy metals and persistent organic pollutants into the body.
Do microplastics (MPs) and nanoplastics (NPs) directly contribute to human carcinogenesis?
This review examines whether microplastics and nanoplastics could directly contribute to cancer development in humans. Evidence from lab and animal studies shows these particles can cause DNA damage, chronic inflammation, oxidative stress, and disrupt important cancer-related signaling pathways. While a direct causal link to human cancer has not been proven yet, the review argues that microplastics should be considered potential cancer-promoting agents that warrant urgent further research.
Polycyclic aromatic hydrocarbons bound to microplastics enhance their bioaccumulation and toxicity, inducing mitochondrial damage and apoptosis in lung epithelium
Researchers tested the toxicity of polystyrene microbeads loaded with polycyclic aromatic hydrocarbons on lung epithelial cells and found that PAH-bound microplastics were significantly more cytotoxic than either contaminant alone. The contaminated microplastics enhanced bioaccumulation of the PAHs in cells and caused mitochondrial damage and programmed cell death. The findings suggest that microplastics may act as carriers that increase the harmful effects of hydrophobic pollutants on lung tissue.

This review explores the emerging relationship between micro- and nanoplastic exposure and cancer risk in humans. Researchers summarized evidence suggesting that microplastics can carry carcinogenic substances and may trigger inflammatory and oxidative stress pathways linked to tumor development. The study highlights that while early evidence raises concern, more research is needed to establish clear causal connections between plastic particle exposure and specific cancer types.
Microplastics and PAHs mixed contamination: An in-depth review on the sources, co-occurrence, and fate in marine ecosystems
This review examines how microplastics and PAHs (cancer-causing chemicals from fossil fuel burning) interact in ocean environments, with microplastics acting as carriers that help spread these toxic chemicals through marine ecosystems. This combined contamination matters for human health because both pollutants can accumulate in seafood and potentially reach people through diet.
Evaluation of the adsorption efficiency of carcinogenic PAHs on microplastic (polyester) fibers—preliminary results
Researchers found that polyester microfibers — the tiny plastic threads shed from clothing during washing — can absorb large amounts of cancer-linked polycyclic aromatic hydrocarbons (PAHs), accumulating up to 1,255 micrograms per gram of fiber, which means microplastics in sewage sludge may be concentrating toxic chemicals before they reach the environment.
Polycyclic aromatic hydrocarbons affiliated with microplastics in surface waters of Bohai and Huanghai Seas, China
Microplastics collected from surface waters of the Bohai and Huanghai Seas in China were found to carry polycyclic aromatic hydrocarbons (PAHs) at concentrations exceeding those in surrounding water, acting as concentrators of these carcinogenic compounds. The study documents that microplastics in heavily industrialized Chinese coastal seas accumulate PAHs that can be transferred to organisms that ingest them.
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.
