Impacts of Air Pollution and Microplastics on Environmental Health in the Era of Climate Change
AI summary Read the abstract
This research review found that tiny plastic particles called microplastics are now being detected inside human bodies—in our blood, lungs, and digestive systems—while air pollution alone kills about 6.67 million people each year. The study shows these pollutants work together to harm our health, made worse by the fact that we're producing massive amounts of plastic (460 million tons in 2021) but recycling only 9% of it. This matters because it means we're facing multiple pollution threats at once that require urgent action to protect public health.
Environmental health challenges in the twenty-first century increasingly arise from the interaction between atmospheric pollution, plastic contamination, and climate change. This study examines the impacts of air pollution and microplastic exposure on environmental health using a quantitative descriptive approach combined with a systematic literature review based on secondary data. Scientific articles were retrieved from PubMed, Scopus, and ScienceDirect, resulting in 156 initial publications, of which 38 studies met the inclusion criteria and were analyzed. The synthesis integrates global datasets from the World Health Organization, Institute for Health Metrics and Evaluation, OECD reports, and national environmental statistics. Findings indicate that ambient air pollution contributes to approximately 6.67 million premature deaths annually, with average PM₂.₅ exposure reaching 29 µg/m³, substantially exceeding the WHO recommended limit of 5 µg/m³. Global plastic production increased dramatically from 2 million tons in 1950 to 460 million tons in 2021, while only 9% of plastic waste is recycled, facilitating the formation of microplastics detected in human blood, lungs, and gastrointestinal samples. Plastic production also generates approximately 1.8 gigatons of CO₂ emissions annually, strengthening the linkage between pollution and climate change. The results highlight synergistic environmental health risks arising from combined exposure to particulate pollution and microplastics, emphasizing the importance of integrated environmental health policies and climate mitigation strategies..

Microplastics: An Overview on Ecosystem and Human Health
AI summary Read the abstract
Tiny plastic bits smaller than 5mm, called microplastics, have been building up in our water, food, and air since plastic use exploded in the 1950s, and this review pulls together what scientists currently know about their effects. These particles can get into our bodies through eating, drinking, and breathing, potentially causing health problems over time, though researchers still need better tools to detect them and fully understand their long-term risks. The takeaway: reducing plastic waste and pushing for stronger regulations isn't just about protecting oceans, it's about protecting what ends up on your plate and in your lungs.
Air pollution and its impacts on health: Focus on microplastics and nanoplastics
AI summary Read the abstract
This review summarizes how airborne micro- and nanoplastics enter the body through breathing, eating, and skin contact, contributing to health risks alongside traditional air pollutants. Plastic particles have been found in human blood, vein tissues, and lungs, and their presence in fine particulate matter in urban air may worsen the inflammation, oxidative stress, and respiratory and heart disease risks already associated with air pollution.
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.
