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.
Chemical Recycling: A False Promise for the Ohio River Valley
Ohio River Valley Institute’s July 2024 report explores the many reasons why chemical recycling is a false promise for the region, from hazardous chemicals, to greenhouse gas emissions, the habitat and ecosystem degradation, to the technology’s expense and general lack of success, and more.
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.
Microplastics and Nanoplastics in Atheromas and Cardiovascular Events
Plastic waste is a growing problem, and as plastics break down the pieces can be problematic. A new study in Science Advances suggests that tiny plastic particles may be the latest environmental contributor to Parkinson’s disease (PD)
The Global Threat From Plastic Pollution
The rational response to the global threat posed by accumulating and poorly reversible plastic pollution is to rapidly reduce plastic emissions through reductions in consumption of virgin plastic materials, along with internationally coordinated strategies for waste management.
