Microplastic pollution: Critical analysis of global hotspots and their impact on health and ecosystems
Summary
This review identifies global microplastic hotspots and examines how these tiny particles enter the human food chain through contaminated meat, dairy, seafood, and plant-based products. Once inside the body, microplastics can cause inflammation, hormonal disruption, oxidative stress, and potentially contribute to cancer and organ damage over time.
This paper examines microplastic hotspots and their drastic effects on human health and the environment pointing out microplastic pollution as one of the biggest global issues. Besides, it analyses the key sources including industrial effluent discharge, littered plastic wastes, and deterioration of synthetic products together with pathways and routes of exposure. The review also focuses on microplastic contamination in food systems such as meat, plant-based products, dairy, and seafood, detailing their entry into the food chain via soil, water, and air. On the other hand, this work also focuses on human health issues including cellular absorption, and bioaccumulation, which results in tissue oxidative stress, inflammation, hormonal imbalance and adverse long-term effects, including carcinogenicity and organ toxicity. The ultimate effects of microplastic pollution on the condition of the soil, water, and fauna and flora of the ecosystem, highlighting on the need for the prevention measures, were also addressed. This paper seeks to critically ascertain the problems posed by microplastics, including their slow biodegradation limit, the absence of proper regulations, and lack of a universally accepted standard. It also highlights that microplastic pollution requires interdisciplinary analyses, future studies, and high standards-compliant policies and regulations. This work raises the alarm for a collective international effort to protect the public health, food, and the earth.

The Environmental Hazards of Micro- and Nanoplastics
Researchers reviewed how microplastics — tiny plastic particles found everywhere in the environment — can enter the body, accumulate in tissues, and disrupt the immune, digestive, and nervous systems, with exposure linked to hormonal imbalances, chronic disease, and cancer risk.
Micro and nanoplastics pollution: A review on global concern and its impacts on ecosystems
This review summarizes the current understanding of micro and nanoplastic pollution globally, covering their sources, movement through ecosystems, and risks to both environmental and human health. The evidence shows that these tiny particles alter soil and sediment properties, disrupt nutrient cycles, and pose potential climate hazards. The authors emphasize that more research is needed on how microplastics move through food chains and affect human health, particularly through contaminated food and water.
Microplastics occurrence, contamination, and effects on human health—a critical review
This critical review examined the occurrence of microplastics in the food chain and their potential effects on human health. The authors found that microplastics enter the body through food packaging and bioaccumulation in animals and plants, and may contribute to oxidative stress and immune system disruption. The review emphasizes the need for greater understanding of microplastic toxicity mechanisms in humans.
Microplastics: Their effects on the environment, human health, and plant ecosystems
Researchers reviewed how microplastics enter the human body through ingestion, inhalation, and skin contact, potentially causing cell damage, hormone disruption, and cardiovascular harm, while also degrading soil quality and stunting plant growth. The review urges urgent action given how thoroughly these particles have infiltrated both human health and agricultural systems.
