A review of the harm of environmental pollutants to human health: Take microplastic, insecticide, and PFAS as examples
AI summary Read the abstract
This review examines the health harms of three major environmental pollutants -- microplastics, insecticides, and PFAS -- summarizing how each class enters the human body and disrupts biological function. The authors highlight shared mechanisms of toxicity and call for stronger regulatory responses.
Environmental pollution is a key issue of social concern. Pollutants generated by a variety of human activities are eventually discharged into the atmosphere, water bodies, and soil, and these pollutants have great negative impacts on the human body. Taking Microplastics (MPs), pesticides, Per- and polyfluoroalkyl substances (PFAS) as examples, this paper explores the sources of three new types of pollutants in the environment and the hazards to the human body respectively, and proposes corresponding management measures in the hope of raising people’s awareness of environmental protection. The results show that MPs mainly come from industrial and agricultural applications and poorly managed wastes, with potential reproductive toxicity and immunotoxicity to the human body; pesticides mainly come from agricultural applications, and high concentrations of pesticides can lead to acute toxicity in the human body, while low concentrations of pesticides may have an immunosuppressive effect on the human body; PFAS mainly come from industrial production, and it has been established that non-alcoholic fatty liver disease (NAFLD) is linked to PFAS exposure. Restricting the production and use of related products and strengthening supervision and monitoring can effectively control environmental pollution and reduce harm to human beings.

Microplastics and environmental pollutants: Key interaction and toxicology in aquatic and soil environments
AI summary Read the abstract
This review tracks how microplastics move through soil, water, and air ecosystems, acting as carriers for other pollutants like pesticides and heavy metals. When microplastics absorb these toxins, the combined effect on organisms can be worse than either pollutant alone. The paper highlights the need for better understanding of how these pollutant combinations affect ecosystems and ultimately human health through contaminated food and water.
Microplastics: Current Status in the Environment and Human Health Risks: A Comprehensive Review
AI summary Read the abstract
This comprehensive review covers the sources, environmental distribution, food chain entry, and human health risks of microplastics, with particular attention to their role as vectors for chemical pollutants and pathogens. It highlights regulatory gaps and emerging mitigation approaches across terrestrial, aquatic, and atmospheric systems.
Microplastics and human health: unraveling the toxicological pathways and implications for public health
AI summary Read the abstract
This review pulls together recent research on how microplastics enter the human body and cause cellular damage through inflammation, oxidative stress, and direct cell injury. The authors highlight that microplastics can also amplify the harmful effects of other environmental pollutants they carry, creating combined health risks that are greater than either threat alone.
Plastic Pollution and Its Effects on Human Health
AI summary Read the abstract
This review examined how plastics enter the environment through poor disposal and fragmentation, then infiltrate food chains and human bodies via ingestion, inhalation, and dermal contact. The authors summarized health risks from both microplastic particles and their associated chemical additives, calling for stronger global policy responses.
