No direct evidence to show plastics cause autism, but what does BPA do?

Recent study suggests BPA exposure in the womb may increase autism risk in boys, but more research is needed.
A study that came out recently has prompted much media attention about the role of plastics in developing autism.
In particular, the study focused on exposure to a component of hard plastics – bisphenol A, or BPA – in the womb and the risk of boys developing this neurodevelopmental disorder.
Importantly, the study doesn’t show plastics containing BPA cause autism.
But it suggests BPA might play a role in oestrogen levels in infant and school-aged boys, which can then affect their chance of being diagnosed with autism.
Let’s tease out the details.
BPA is a component of hard plastics that has been used for a few decades. Because BPA is found in plastics used for food and some drink containers, many people are exposed to low levels of BPA every day.
But concerns about how BPA impacts our health have been around for some time because it can also weakly mimic the effects of the hormone oestrogen in our body.

Climate scientists and advocates long held an optimistic belief that once impacts became undeniable, people and governments would act. This overestimated our collective response capacity while underestimating our psychological tendency to normalise, says Rachit Dubey, assistant professor at the department of communication, University of California.
