An analysis of chemicals in baby teeth suggests that exposure to lead in pregnancy or shortly after birth might make infants more vulnerable to developing autism.

Investigators have found that babies who don't get enough zinc and manganese during the same time frame may also face an increased risk for the developmental disorder.

Beyond finding a link between autism risk and varying exposure to lead and/or zinc and manganese, evidence was also found that metal exposure in early infancy might affect autism severity when it develops.
