Introduction to Microplastics in Pediatric Health
Definition and Classification
- Microplastics defined:
- Plastic particles < 5mm in diameter
- Primary microplastics (manufactured small)
- Secondary microplastics (breakdown products)
- Nanoplastics (particles < 100nm)
- Common types:
- Polyethylene (PE)
- Polypropylene (PP)
- Polyethylene terephthalate (PET)
- Polystyrene (PS)
- Polyvinyl chloride (PVC)
Pediatric Vulnerability
- Enhanced susceptibility factors:
- Higher consumption per body weight
- Developing organ systems
- Immature detoxification pathways
- Extended exposure window
- Hand-to-mouth behavior
- Critical developmental windows:
- Prenatal period
- Early infancy
- Childhood
- Adolescence
Exposure Routes
Primary Exposure Pathways
- Ingestion sources:
- Contaminated food and beverages
- Plastic packaging leachates
- Seafood contamination
- Processed foods
- Drinking water
- Bottled water
- Tap water
- Microplastic-contaminated sources
- Breast milk
- Transfer of maternal exposure
- Plastic storage containers
- Contaminated food and beverages
- Inhalation exposure:
- Airborne particles
- Indoor dust
- Synthetic textiles
- Vehicle emissions
- Dermal contact:
- Personal care products
- Clothing
- Toys
- Environmental contact
Special Considerations
- Placental transfer:
- Documented presence in placental tissue
- Potential fetal exposure
- Impact on fetal development
- Early-life exposures:
- Baby bottles and feeding equipment
- Plastic toys
- Pacifiers
- Baby care products
Health Effects
Systemic Effects
- Endocrine disruption:
- Thyroid function alterations
- Growth hormone disruption
