Episode notes
Tiny Microplastics Abound Indoors
- Indoor air contains smaller microplastics (1 to 10 microns) more than previously known.
- These tiny plastics are more likely to be inhaled or ingested, increasing exposure risks.
Plastic Chemicals Cause Harm
- Plastics contain harmful chemicals like plasticisers that act as endocrine disruptors.
- These chemicals can cause health issues like type 2 diabetes, which raises concern.
Practical Ways to Cut Microplastics
- Use less plastic kitchenware, switch to non-plastic chopping boards and utensils.
- Ventilate homes, vacuum often, and reduce synthetic clothing and dryer use to lower indoor microplastic levels.
