BPA (Bisphenol A) is an industrial chemical used primarily in plastic production (chemical formula: C₁₅H₁₆O₂). Since its commercialization in the 1950s, it has become one of the most widely produced chemicals globally, with annual production exceeding 5 million tons.
Common Uses
Polycarbonate Plastics (75%) – Used in:
Water bottles
Food containers
Electronics casings
Epoxy Resins (20%) – Used in:
Food can linings
Dental sealants
Other Applications – Thermal paper (receipts), flame retardants, etc.
Health Concerns
Exposure Routes:
Ingestion (from plastic containers)
Skin contact (handling receipts)
Inhalation (industrial settings)
Potential Risks:
Endocrine disruption (estrogen-like effects)
Developmental issues (especially in fetuses and infants)
Linked to obesity, diabetes, and reproductive problems
High-Risk Groups: Pregnant women, infants, and young children
How to Reduce Exposure
✔ Avoid heating food in plastic containers
✔ Choose BPA-free products (look for labels)
✔ Use glass/stainless steel containers instead
✔ Minimize handling thermal paper receipts
✔ Discard old or scratched plastic items
Regulations Worldwide
Banned in baby bottles: EU, U.S., China, Canada
Canada: First to declare BPA a toxic substance (2010)
Safe intake limit: Typically 0.05 mg/kg body weight/day
Future & Alternatives
Some BPA substitutes (e.g., BPS, BPF) may pose similar risks
Research ongoing for safer, non-toxic alternatives
Demand growing for sustainable packaging solutions
Key Takeaway
While BPA is useful in modern manufacturing, its potential health risks warrant caution. Consumers can reduce exposure by making informed choices and opting for safer alternatives when possible.
