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 collected a number of plant and animal specimens along the way and made scientific observations. Due to the rough terrain, the men only managed to travel about 12 to 14 miles on a good day. Lewis and Clark made it back to St. Louis on September 23, 1806. Due to how long they were gone, many feared that they died on their journey. Despite the hardships the team faced while on this expedition, only one man died on the trip.
