You're right, not a good source. Google does a poor job of bringing up unbiased soruces. A better term to search for is expanded polystyrene foam. Here are some sources:
The EU has decided to ban throwaway polystyrene foam but I don't know if this counts for much as I don't know how much science was taken into account. There will be a comprehensive risk assessment by the EPA: https://www.epa.gov/assessing-and-managing-chemicals-under-t....
My worry is when packaging EPS breaks down into tiny particles that could be inhaled. This cannot be great.
