Maybe, but pollution has been linked with increase of several troubles in the childbirth, like low weight or premature births. https://pubmed.ncbi.nlm.nih.gov/21112090/ https://pubmed.ncbi.nlm.nih.gov/21112090/ Is well known that preterm babies have an increased risk of dying and show damage in the nervous system later. So, how many of those 300 babies were also preterm or low weight? We don't know. We lack of the necessary info here to evaluate the problem.
