Microplastics (MPs) in the environment: sources, pathways, human health issues and mitigation strategies
AI summary Read the abstract
Tiny plastic bits called microplastics—smaller than a pencil eraser—are turning up in our air, water, soil, and food, and can stick around for centuries without breaking down. This review pulls together what scientists currently know about where these particles come from and how they might harm our health, while pointing out that researchers still lack reliable, affordable ways to measure microplastics and don't yet fully understand the risks they pose. The bottom line: microplastic pollution is a growing concern worth watching, but there's still a lot we don't know about exactly how it affects our bodies.
Microplastics (MPs) pollution has become a serious environmental threat in the 21 st century. Plastics are widely used but improperly disposed of, resulting in large amounts of plastic waste that end up in landfills and/or water bodies, contaminating the environment (terrestrial, aquatic, atmospheric, and biotic ecosystems) through various pathways. MPs (particles <5 mm in size), derived from primary and secondary sources, are a heterogeneous mixture of plastic particles of varying shapes, sizes, colors, and chemical composition. Commonly found plastic types include polyethylene terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyurethane (PU), and polyester, etc. MPs are ecotoxic and long-lasting (they may persist for 100 to 1000 years) and adversely affect ecosystems, human health, and all other forms of life (aquatic life, wildlife, livestock, birds, etc.). This paper comprehensively reviews existing knowledge on MPs pollution, pathways, fate, and distribution across different ecosystems, their ecotoxic effects, mitigation and remediation strategies, knowledge gaps, and future research recommendations. Several research efforts have focused on developing standardized, efficient analytical techniques for detecting, measuring, and mitigating MPs pollution across different ecosystems, but significant research gaps remain. There is a lack of standard, efficient, and cost-effective analytical techniques suitable for large-scale applications to detect and measure MPs. Sufficient monitoring data on MPs is also scarce and not readily available. The majority of terrestrial sources of MPs remain overlooked and receive inadequate attention in current research efforts. Several knowledge gaps persist regarding current and future environmental and human health risks posed by MPs pollution. Policy measures for the mitigation and remediation of MPs pollution have been discussed.

Microplastics in the environment: sources, impacts, and strategies for mitigation
AI summary Read the abstract
Tiny plastic bits called microplastics, created when everyday plastic items break down, have been found in surprising places, including our blood, fish, soil, and water, and scientists are still working to understand exactly how harmful they are. This review pulls together what researchers currently know about where these particles come from, how they spread, and what methods might remove them, while pointing out that we still lack solid answers on their long-term health effects and the best ways to clean them up. The takeaway: microplastic pollution is a growing concern worth watching, even though the science on its full impact to our bodies is still catching up.
Unraveling Microplastics: Sources, Environment and Health Impacts, and Detection Techniques
AI summary Read the abstract
This research review summarizes what we know about microplastics—tiny pieces of plastic pollution that are now found everywhere in our environment, including inside human bodies. Scientists have found these plastic particles in our water, food, and even our blood, but we still don't fully understand what health problems they might cause. The study shows we need better ways to detect and measure microplastics, plus more research and government action to protect people from this growing pollution problem.
Tracing the microplastic cycle in ecosystems with sources biological interactions and mitigation strategies

Tiny plastic particles called microplastics have worked their way into soil, water, air, plants, animals, and eventually our bodies, and scientists still aren't sure exactly what long-term harm this causes to our health. This review pulls together existing research on how microplastics move through ecosystems and accumulate in living things, while also highlighting promising cleanup methods—but it stresses that more research is urgently needed to fully understand the risks and find better solutions.
Sources, Environmental Fates, Human Exposure Pathways, and Health Impacts of Micro- and Nanoplastics
AI summary Read the abstract
Tiny plastic particles called microplastics and nanoplastics are now found everywhere—in our food, water, and air—and this review pulls together what scientists currently know about how they get into our bodies and what they might do once there. The concern isn't just the plastic itself, but that these particles can carry along other harmful chemicals (like BPA and heavy metals) and may disrupt hormones and metabolism, with the smallest particles even able to slip past the body's natural protective barriers. The research is still catching up, though—scientists don't yet have long-term human studies to fully confirm the risks, so this paper mainly highlights what we need to study
Microplastic Pollution in Aquatic and Terrestrial Ecosystems: Health Impacts and Remediation Strategies: A Systematic Review
AI summary Read the abstract
Tiny plastic bits called microplastics, shed from things like tires, laundry, and cosmetics, are everywhere in our water and soil, and this review of 54 existing studies confirms they can soak up pollutants and work their way into our food chain. While scientists agree this poses a real risk to both nature and human health, the research is still inconsistent, so the long-term effects on our bodies aren't fully understood yet. The takeaway: microplastic exposure is likely unavoidable in daily life, but more standardized research is needed before we know exactly how worried to be.
