Kids who are exposed to certain harmful chemicals in the environment might have a harder time controlling their impulses or stopping themselves from doing something they shouldn't.

The study looked at how chemicals during pregnancy affect kids' behaviour. It found that girls exposed to more of these chemicals had more behavioural problems, which can include trouble controlling impulses.
The study found that girls exposed to certain chemicals before birth had more trouble controlling their impulses, based on what their parents reported. This supports the idea that these chemicals can affect kids' self-control.

The study looked at whether being exposed to a certain chemical (PBB) as a baby or in the womb led to attention or autism issues, which are linked to poor impulse control. It found no link, so it doesn’t support the idea that this chemical causes such problems.
Prenatal Exposure to Endocrine-disrupting Chemicals in Relation to Autism Spectrum Disorder and Intellectual Disability
The study looked at whether certain chemicals during pregnancy are linked to autism or intellectual disability, but it didn’t test self-control or impulse control in kids. So, it doesn’t support the claim about those chemicals affecting inhibitory control.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
