Abstract

The paper explores how historical mercury deposition associates with the incidents of autism, identified in individuals aged from 3 to 21 in California from 2001 to 2007. The association between mercury deposits and the prevalence of individuals with autism aged from 3 to 21 in California was explored using the data from the National Atmospheric Deposition Program and the U.S. Education Department. A correlation analysis is applied to find if a relationship between mercury deposits and the autistic individuals in California. A regression test is run showing that for every 2.41ng/square meter per year increase of mercury deposits in California, there is a corresponding 3.55 person increase of autistic individuals aged from 3 to 21 historically from 2001 to 2007. Due to constraint factors in the research (please see the conclusion section), the comparison study did not show a statistically significant difference but the study indicated the importance of examining the effect of environmental toxins and their impact on human health.
