We talked today in class about neurological deficiencies that can be related to specific chemical concentrations in the body passed through the umbilical chord. Well, here's another example of that! A study done in northern Ecuador has related intellectual slowness with pesticide exposure. Children born from mothers who work as flower-growers and/or have high, long-term exposure to pesticides can be up to two years behind by the time they reach the ages of 6 - 8. The most noticeable areas of cognitive deficits were in motor speed, motor coordination, and visual tasks like copying a picture. These effects were not observed in children who only have a father who works in the flower fields, thus, emphasizing the impact that a mother's exposure can have on the development of her future children.
