Microplastics: Detection in human samples, cell line studies, and health impacts

Area of Science:

• Environmental Science
• Toxicology
• Human Health

Background:

• Microplastics (MPs) contaminate diverse environmental compartments and enter the human body via ingestion, inhalation, and dermal contact.
• Detection of MPs in human tissues like stool, placenta, lungs, and blood raises significant health concerns.
• Limited knowledge exists regarding human exposure levels and the toxicological effects of microplastics.

Approach:

• This review synthesizes current research on MP detection in human matrices.
• It provides an overview of sample preparation and analytical methods for human samples.
• The article summarizes the impact of MPs on human cell lines and overall health.

Key Points:

• Microplastics are ubiquitously detected across environmental compartments and have been found in numerous human tissues.
• Routes of human exposure include ingestion, inhalation, and dermal absorption.
• Analytical methodologies for detecting MPs in human samples are evolving.

Conclusions:

• Further research is crucial to understand the full extent of human exposure to microplastics.
• The potential health implications of microplastic accumulation in the human body require thorough investigation.
• Developing standardized methods for MP detection and risk assessment is essential.
