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.
Lewis chose his friend William Clark to help him. When the trip began, the two leaders had 14 soldiers with them, along with nine frontiersmen, Clark's servant, York, and a couple of boatmen. 2 The plan was to start the expedition at the Missouri River, and so they did on May 14, 1804. A couple of months later, they met some Indians in what is now Council Bluffs, Iowa. After meeting the Mandan Indians, Lewis and Clark's team built Fort Mandan close to present-day Stanton, North Dakota.
