Health Hazards by Component:

Chemical Additives
- Sulfur dioxide (preservative): Can cause asthma attacks at >10mg/kg⁵
- Fluorescent whiteners: Banned under GB/T 24398-2009¹
Heavy Metals
- Lead/Cadmium: Limited to <0.2mg/kg (GB 31604.49)⁶

Microbial Risks
- Mold growth in improperly stored bamboo products

The Environmental and Health Impacts of Different Chopstick Materials?

Leading paragraph.
Your chopstick choice affects both your body and the planet—here’s the breakdown.

Snippet paragraph.
Bamboo chopsticks decompose in 4-6 months (best eco-option)⁴, while plastic-coated wood releases microplastics. Carbonized bamboo resists mold naturally without chemicals⁵.

Material Comparison Table:

Material	Decomposition	Chemical Risk	Certifications
Bamboo	4-6 months	Low (if unbleached)	FSC, ISO 9001
Wood	6-12 months	Medium (potential coatings)	GB 19305
Crops fiber	3-4 months	Low	GB/T 24398-2009
Carbonized bamboo	5-7 months	None	T/ZZB 2109-2021⁵

Conclusion

Choose chopsticks with visible safety certifications and natural materials—your health and environment will thank you.
