Impact of Pesticide Exposure on Cognition in Children
A number of previous studies have documented that exposure to cholinesterase-inhibiting pesticides such as organophosphates (OPs) and carbamates constitutes a major health problem. A number of studies have also examined the impact of OP poisoning and the impact of routine long- term exposure to pesticides in adults. The impact of long-term exposure to pesticides on children has been relatively unexplored. This study utilized an experimental design with an experimental group of children recruited who live either on or next to an active field or farm in Northeastern North Dakota and a control group of children living at least one mile from an active field or farm. Children were compared on a number of cognitive, motor and school-achievement measures. Children were also asked to give a urine and blood sample which was used by the Centers for Disease Control (Atlanta, GA) to determine the concentrations of several pesticides that are heavily applied in this section of North Dakota.
