Methods for the detection of microplastics in mammals
AI summary Read the abstract
Scientists now detect microplastics in human blood, lungs, placentas, and other tissues, but the field still lacks a single gold-standard method for measuring them. This review compares the strengths and limitations of current detection techniques — including spectroscopy, microscopy, and chemical digestion — to help standardize how microplastics in the human body are quantified, which is a prerequisite for accurately assessing health risks.
The mass manufacture and extensive usage of plastics have brought about the spread of microplastics throughout the whole environment and even into the bodies of humans and animals. The toxic effects of microplastics cannot be ignored and their accumulation in the body is potentially dangerous. Therefore, scientists have used different methods to observe the morphology of microplastics in the mammal body and to detect and evaluate the levels of microplastics in the body. As a result, the toxicological consequences of plastic particles on the body are well understood. This review summarized some common methods of detecting microplastics in mammals, especially humans, by reviewing the research on microplastics conducted by different research groups in recent years. and evaluated the characteristics, detection goals, and advantages and disadvantages of each method. This establishes a more comprehensive overview of current microplastic detection technologies and can create a theoretical basis for future analysis of microplastic dynamics.

Advancements in Assays for Micro- and Nanoplastic Detection: Paving the Way for Biomonitoring and Exposomics Studies
AI summary Read the abstract
This review surveys the latest methods for detecting micro and nanoplastics in human tissues and bodily fluids, including blood, breast milk, stool, and lung tissue. Current detection techniques have significant limitations in sensitivity and standardization, making it difficult to accurately measure how much plastic is in people's bodies. Developing better, scalable detection methods is essential for understanding the true extent of human microplastic exposure and its health consequences.
Effects of Microplastics on the Human Body and Methods of Detection
AI summary Read the abstract
This review summarized how microplastics and nanoplastics enter the human body through ingestion, inhalation, and skin contact, and outlined current detection methods used to identify them in biological samples. The authors found that while evidence of tissue accumulation is growing, health effect thresholds and standardized exposure metrics are still lacking.
Microplastics: challenges of assessment in biological samples and their implication for in vitro and in vivo effects
AI summary Read the abstract
This review covers how microplastics enter the human body through ingestion and inhalation, the challenges of detecting and measuring them in biological samples, and the evidence for harmful effects ranging from inflammation to hormonal disruption. Standardising methods for measuring microplastics in tissues and bodily fluids is a key obstacle to advancing human health research. The review provides a useful framework for understanding what we know and what still needs to be established about microplastic risks to people.
Methods for identifying microplastics in human biofluids: scoping review
AI summary Read the abstract
Tiny plastic particles called microplastics are showing up in human body fluids, and scientists are still figuring out the best way to detect and measure them. This review looked at existing studies to compare the different testing methods researchers use, finding that there's currently no standard approach—which makes it hard to know exactly how much plastic is in our bodies or compare results across studies. This matters because before we can understand the health risks of microplastics, scientists need reliable, consistent ways to detect them in the first place.
Detection of nano- and microplastics in mammalian tissue
