How do mercury emissions affect pregnant mothers, the unborn and toddlers? Do the level of emissions impact autism rates? Does it matter whether a mercury-emitting source is 10 miles away from families versus 20 miles? Is the risk of autism greater for children who live closer to the pollution source? A newly published study of Texas school district data and industrial mercury-release data indeed shows a statistically significant link between pounds of industrial release of mercury and increased autism rates.
