14 Questions
How can individuals reduce their exposure to plastics according to Landrigan?
By drinking out of steel cups or bottles instead of plastic ones and not microwaving food in plastic containers.
What is the average amount of plastic waste generated by the average American per year?
487 pounds
According to Landrigan, where should the heavy lifting in reducing plastic use be done?
At the policy level
What is the United Nations negotiating since 2022?
The world’s first-ever plastics pollution treaty
What impact does the New England Journal of Medicine study have on the urgency of plastic pollution negotiations?
Increase the urgency
Why does Landrigan mention that individuals can do a little bit in reducing plastic use?
The heavy lifting needs to be done at the policy level
Why does Landrigan recommend not microwaving food in plastic containers?
Heat speeds up the breakdown of plastics
What alternative does Landrigan suggest for drinking instead of plastic cups or bottles?
Steel cups or bottles
How does Spaeth feel about the impact of research on plastic pollution?
Optimistic
What did the researchers find about patients with microplastics and nanoplastics in their plaque?
They were about 4.5 times more likely to have a heart attack, stroke, or death in the next several years.
What is one possible way suggested in the text on how micro- and nanoplastics could contribute to heart attacks or stroke?
Inducing inflammation as macrophages gather around to eliminate the particles
Why might plaques with increased inflammation due to micro- and nanoplastics be more vulnerable to causing problems in the future?
Because they might more easily break off and enter the bloodstream
What role do macrophages play in the potential harm caused by micro- and nanoplastics in the plaque?
They could be converging to rid the body of foreign particles, potentially leading to increased inflammation
What is one concern mentioned about chemicals in plastics in addition to the physical particles themselves?
They may disrupt natural hormone production and trigger inflammation
