Microplastics and Human Health: Global Perspectives in Environmental and Occupational Health: Organ System Effects and Clinical Implications

Microplastics and nanoplastics are increasingly being detected in environmental media and selected human biological samples, raising important questions about their potential effects on human organs and physiological systems.
Microplastics and Human Health: Global Perspectives in Environmental and Occupational Health – Volume II: Organ System Effects and Clinical Implications examines the emerging evidence concerning how microplastic exposure may affect the human body.
Building directly on the scientific foundations established in Volume I, this volume moves from exposure and toxicological mechanisms to organ-specific health interpretation. Rather than repeating the basic science of microplastics, it evaluates what current experimental, biomonitoring and human evidence suggests about possible effects on major biological systems.
The book examines:

• respiratory deposition, clearance and pulmonary responses;
• gastrointestinal effects and interactions with the gut microbiome;
• cardiovascular, hepatic and renal effects;
• nervous-system and neurobehavioural responses;
• endocrine, metabolic, reproductive and developmental effects;
• immune responses, systemic inflammation and potentially susceptible populations;
• human biomonitoring, observational studies and emerging clinical evidence;
• association versus causation and the strength of current epidemiological evidence.

Particular attention is given to the distinction between particle detection, biological interaction, measurable biological response and clinically significant disease.
Experimental studies have identified mechanisms such as inflammation, oxidative stress, altered cellular function and metabolic disturbance, but these findings cannot automatically be translated into human disease. Similarly, the detection of microplastics in blood, lung tissue, placenta and other biological samples confirms internal exposure but does not, by itself, establish toxicity or causation.
Throughout the volume, evidence is interpreted according to its strength, relevance and limitations. Established findings are distinguished from emerging associations, biologically plausible mechanisms and areas where evidence remains insufficient.
Written for environmental and occupational health professionals, health and safety practitioners, toxicologists, researchers, occupational hygienists, healthcare professionals, regulators, engineers, policymakers, educators and students, this volume provides a balanced and evidence-based assessment of the rapidly developing science linking microplastic exposure with potential human health effects.
Rather than promoting either alarm or complacency, Volume II: Organ System Effects and Clinical Implications provides the critical framework needed to understand what current evidence shows, what remains uncertain and what can reasonably be concluded about human health.
