Presence of microplastics in human stomachs
This study presents the first definitive confirmation of microplastic presence in the human stomach, based on samples from 26 cadavers. 97 microplastic particles were extracted from stomach contents, across all 26 individuals, revealing a universal prevalence of microplastics in the cadavers.
Association of mixed exposure to microplastics with sperm dysfunction: a multi-site study in China
Our findings highlight the potential reproductive health risks posed by microplastic contamination, particularly PTFE, a non-stick pan coating material, and raise concerns about the potential of urine testing as an indicator of male reproductive microplastic exposure. Future research is warranted to further elucidate the mechanisms underlying the adverse effects of microplastics on male fertility and cross-generational effects.
Microplastics in the Olfactory Bulb of the Human Brain
This case series provides evidence of MPs found in the human olfactory bulb, suggesting a potential pathway for the translocation of MPs to the brain. The findings underscore the need for further research on the health implications of MP exposure, particularly concerning neurotoxicity and the potential for MPs to bypass the blood-brain barrier.
Discovery and analysis of microplastics in human bone marrow
Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) is an emerging thermal analysis technique that reliable qualified and quantified data for MPs risk assessment of human health [15], [26]. Laser direct infrared spectroscopy (LD-IR) has been widely used to characterize of MPs, including their type, size, and morphology [12]. This study utilized Py-GC/MS, LD-IR, and scanning electron microscopy (SEM) to analyze and identify the accumulation of MPs in the bone marrow. The results provide crucial data for evaluating the risks of MPs on human haematopoietic injury, and support further studies with larger sample sizes and more detailed designs to explore the health implications of MPs in human bone marrow.
Bioaccumulation of Microplastics in Decedent Human Brains Assessed by Pyrolysis Gas Chromatography-Mass Spectrometry
Rising global concentrations of environmental micro- and nanoplastics (MNPs) drive concerns for human exposure and health outcomes. Applying pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) methods to isolate and quantify MNPs from human samples, we compared MNP accumulation in kidneys, livers, and brains.
Identification and analysis of microplastics in human lower limb joints
Our findings demonstrate the presence of MPs in human joints and suggest that further studies are needed to explore the intricate associations between MPs and anatomical location, clinical diagnosis, and local cellular responses.
Hazardous Chemicals in Recycled and Reusable Plastic Food Packaging
All types of water pipes, not only lead, can release chemicals into drinking water. Plastic pipes, which are constructed from potentially dozens of different chemicals, release more contaminants into drinking water than unlined metal pipes, which are built of few materials. Communities need to understand the potential health risks associated with different water pipe materials so that they do not end up with what’s known as a “regrettable substitution,” or a situation in which a selected alternative turns out to be just as bad, if not worse, as the original option.
The Perils of PVC Plastic Pipes

PVC Poison Plastic
Every day, PVC production exposes communities around the country to vinyl chloride and other PVC chemicals, a result of the inadequate U.S. regulatory system that allows the use of the most hazardous chemicals and plastics. This investigation uncovers the largest polluters of vinyl chloride in the U.S. and maps the communities regularly exposed to this dangerous chemical and its waste products.
The Minderoo-Monaco Commission on Plastics and Human Health
The Minderoo-Monaco Commission on Plastics and Human Health has produced an extensive analysis of the plastics’ negative impacts on: i) human health and well-being focusing on vulnerable populations, ii) on the global environment focusing on ocean health, and iii) the economy. The report includes highly valuable sustainable solutions that can be implemented by governments and industries to minimize the negative consequences of global plastic contamination This is an urgent problem that must be addressed in the worldwide agenda in parallel to climate change, as they are closely interconnected.
Detection of Microplastics in Human Saphenous Vein Tissue Using μFtir: A Pilot Study
Microplastics (MPs) are ubiquitous in the environment, in the human food chain, and have been recently detected in blood and lung tissues. To undertake a pilot analysis of MP contamination in human vein tissue samples with respect to their presence (if any), levels, and characteristics of any particles identified. This study analysed digested human saphenous vein tissue samples (n = 5) using μFTIR spectroscopy (size limitation of 5 μm) to detect and characterise any MPs present.
Microplastics Occurrence, Health Effects, and Mitigation Policies: An Evidence Review for the California State Legislature
This report responds to a joint request from the California Senate Committee on Environmental Quality and the Assembly Committee on Natural Resources for evidence concerning human health effects of microplastics and public policies related to microplastics prevention and mitigation.
Research was conducted by the California State Policy Evidence Consortium (CalSPEC), anindependent program administered through the University of California Center Sacramento (UCCS) and composed of faculty, staff, and graduate student researchers across UC campuses who evaluate evidence to inform public policy deliberations.
An Introduction to Plastics and Toxic Chemicals
The health and environmental impacts of plastics are a global crisis. Scientific evidence shows that we have broken through the “planetary boundaries” for chemical and plastics pollution, meaning that production and emissions may be threatening the stability of the entire global ecosystem. To best understand what plastics pollution is, one must understand what plastic is: a material made from carbon (fossil fuels) and chemicals. Plastics do not exist without chemicals, and harmful chemicals are released at every phase of the plastics life cycle – from oil extraction to plastics production, transport, use, and disposal.
Invisible, Unbreakable, Unnatural: PFAS Contamination of U.S. Surface Waters
While PFAS compounds are believed to be ubiquitous in U.S. waterways, no nationwide surface water quality survey exists. As a result, the levels and effects of PFAS are unknown for many rivers, streams, lakes, and other U.S. surface waters that serve as drinking water sources, recreational waters, and fisheries. To address this troubling lack of information about the presence of, and dangers posed by, PFAS in U.S. surface waters, Waterkeeper Alliance contracted with Cyclopure, Inc., a materials science and environmental engineering firm headquartered in Illinois, to help conduct a monitoring project in which we worked with more than 100 Waterkeeper groups across the United States on an unprecedented initiative to test U.S. surface waters for PFAS contamination.
The Price of Plastic Pollution: Social Costs and Corporate Liabilities
Plastics harm people, the environment, and the economy (“social costs”). Some social costs will inevitably turn into compensation claims against the plastics industry (“corporate liabilities”), which may present these claims to their insurers. In this report, for the first time, we provide quantitative estimates of both the social costs and the corporate liabilities emerging from all forms of plastic-related pollution.
It’s as If They’re Poisoning Us’: The Health Impacts of Plastic Recycling in Turkey.
Plastic recycling in Turkey is harming the health of many people and degrading the environment for everyone, Human Rights Watch said in a report released today. The 88-page report, “‘It’s as If They’re Poisoning Us’: The Health Impacts of Plastic Recycling in Turkey,” documents the consequences of the Turkish government’s ineffective response to the health and environmental impacts of plastic recycling on the right to health.
Raman Microspectroscopy Detection and Characterisation of Microplastics in Human Breastmilk
The evidence of microplastics (MPs) in human breastmilk, coupled with the previous discovery of these microparticles in the human placenta, represents a great concern, since it impacts the extremely vulnerable population of infants. In fact, the chemicals possibly contained in foods, beverages, and personal care products consumed by breastfeeding mothers may be transferred to the offspring, potentially exerting a toxic effect. Hence, it is mandatory to increase efforts in scientific research to deepen the knowledge of the potential health impairment caused by MP internalisation and accumulation, especially in infants, and to assess innovative, useful ways to reduce exposure to these contaminants during pregnancy and lactation.
Plastics in Agriculture – An Environmental Challenge
The Foresight Briefs are published by the United Nations Environment Programme to highlight a hotspot of environmental change, feature an emerging science topic, or discuss a contemporary environmental issue. The public is provided with the opportunity to find out what is happening to their changing environment and the consequences of everyday choices, and to think about future directions for policy. The 29th edition of UNEP’s Foresight Brief explores the use of plastic in agriculture and the significant waste problem this entails which impacts on soil health, biodiversity, productivity and food security.
First Evidence of Microplastics in Antarctic Snow
In recent years, airborne microplastics have been identified in a range of remote environments. However, data throughout the Southern Hemisphere, in particular Antarctica, are largely absent to date. We collected snow samples from 19 sites across the Ross Island region of Antarctica. Suspected microplastic particles were isolated and their composition confirmed using micro-Fourier transform infrared spectroscopy (µFTIR).
Reckoning With the U.S. Role In Global Ocean Plastic
Reckoning with the U.S. Role in Global Ocean Plastic Waste calls for a national strategy by the end of 2022 to reduce the nation's contribution to global ocean plastic waste at every step - from production to its entry into the environment - including by substantially reducing U.S. solid waste generation.
