Mercury is released into the environment by factories as toxic waste which gets absorbed into the water table and further travels into the irrigated farm land ending up in produce which is consumed by the people of the region. The research conducted by Palmer, Blanchard, Stein, Mendell and Miller indicates that “on average, for each 1000 lb of environmentally released mercury, there was a 43% increase in the rate of special education services and a 61% increase in the rate of autism.
The association between environmentally released mercury and special education rates was fully mediated by increased autism rates” (Palmer et al, 2006). This depicts that there exists a positive relationship between increase in autism and the release of mercury into the environment.
Multiple approaches are available to treat autism and slow down its effect while helping the patient develop themselves without being hampered significantly by the disorder. However the selection of the treatment approaches is of personal taste, opinion and convenience of the parents and the guardians of the patients.
