Human studies have reported developmental effects, such as CNS dysfunction, attention deficits, and minor craniofacial and limb anomalies, in the children of pregnant women exposed to high levels of toluene or mixed solvents by inhalation.
Contrary to popular belief, the expedition DID NOT begin in St. Louis, Missouri. The first entry in the Lewis and Clark Expedition Journals state that the journey began in Pit â¦ tsburgh, PA on August 30, 1803. Lewis, who had been assigned by Jefferson sailed down the Ohio River with supplies towards St. Louis.
Although the expedition did make notable contributions to science, scientific research itself was not the main goal of the mission. References to Lewis and Clark scarcely appeared in history books even during the United States Centennial in 1876 and the expedition was largely forgotten. Lewis and Clark began to gain new attention around the start of the 20th century.
