Area of Science:

Environmental Science
Analytical Chemistry
Toxicology

Background:

Global plastic production has surged since 1950, leading to widespread environmental microplastic contamination.
Microplastics are increasingly detected in the environment, raising concerns about potential human uptake.
This study addresses the critical need to detect microplastic particles within biological organisms.

Purpose of the Study:

To develop and validate an extraction method for detecting microplastic particles in human and animal biological samples.
To assess the impact of the extraction process on the integrity of various plastic types.
To establish a reliable method for quantifying microplastic contamination in biological tissues.

Main Methods:

Human blood and animal tissues were used as biological matrices.
Various lysis solutions were tested for their efficiency in degrading biological material and their effect on plastics.
Atomic force microscopy (AFM), electron microscopy (EM), and Fourier transform infrared spectrometry (FTIR) were employed for analysis.

Main Results:

Fourier transform infrared spectrometry (FTIR) successfully differentiated and identified plastic types including polyamide (PA), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC).
Polyvinyl chloride (PVC) exhibited surface alterations post-extraction, such as irregular structures.
The method demonstrated a high overall recovery rate of 99.12±0.67%, indicating efficient particle retrieval.

Conclusions:

The developed extraction method is effective for isolating microplastics from human and animal tissues.
The method ensures minimal alteration to the plastic particles, preserving their integrity for analysis.
This validated technique provides a reliable tool for studying microplastic exposure in biological systems.
