Perchlorate is a natural and manmade chemical used in rocket fuel, fireworks and fertilizers. As a contaminant of water, it has been found in 4 percent of U.S. public water systems. In a study, researchers found that high perchlorate levels in pregnant women can be disruptive to thyroid hormones, which are important to proper brain development in babies. The study stresses that if the perchlorate levels are high during the mother’s first trimester, their babies would be more likely to have lower IQ’s later on in life.
An article about the study can be found on the Scientific American website: http://www.scientificamerican.com/article/lower-iq-in-children-linked-to-chemical-in-water/
This article raises awareness to further investigate the perchlorate levels in our public water systems and the potential health risks associated with them. Moreover, this study shows that air pollutants do not only affect the air, but can contaminate our waters and perhaps other resources, creating more ways to pose dangers to our health.
