ABSTRACT
The incidence of infantile autism due to developmental brain disorders has been permanently increasing in many parts of the world. Autism is characterized by impairments of communication and reciprocal social interaction and by restricted repetitive behaviours or interests. The causes of these disorders are not yet known. Experimental studies and clinical observation suggest that genetic and environmental factors could converge to result in neurotoxic mechanisms. These may lead to the development of autistic spectrum disorders (ASD). Several recent studies have indicated that perinatal exposure to environmental toxins may be the risk factor for ASD, among them: polybrominated diphenyl, esters, phthalates, bisphenol A, tetrabrombisphenol A, solvents, pesticides, and heavy metals. They can easily pass the placental and blood brain barriers and affect brain development.
