I believe that everyone who loves to read the news must have seen reports about the harm of Ps lid , but is there any health hazard to the human body caused by the styrene released by ps lid?

The lid made of polystyrene releases styrene monomer when heated. Indeed, a small amount of styrene monomer may not be completely polymerized and remain in the finished product during the production process of polystyrene. In addition, the stability of polystyrene products is not very good. During use, it may be under high temperature and other conditions. Decomposition and polymerization produce a small amount of styrene monomer. Therefore, the Hong Kong Center for Food Safety recommends that the use temperature of polystyrene products should generally not exceed 100°C.

As for the health hazards of styrene released from the lids of hot drinks, we must first clarify the concept that the dose determines the toxicity. In other words, whether the styrene released from the lids is harmful to health depends on its amount.

So, don’t worry too much about using a Paper cup sleeve or ps lid.
