The following document looks at the subject of autism from an environmental perspective. Autism is an increasing condition in developed countries and has both genetic and environmental factors involved. This study looks at autism density in the Southern California Unified School District system in conjunction with the presence of both mercury and lead presence. This study found that there was some correlation between high presence of these two substances and high case density in areas of high population.
