Toxic metals (MT) are the major pollution to the land (37.3% in Europe), which are produced mainly by industrial activities, entering a far part of our life cycle, through the skin, breathing, ingestion of foods and water. Especially children in the first three years of life are biologically more vulnerable. The spreading epidemic of Autism and developmental disorders, that has been recorded in industrialized countries during the last 20 years is a sensitive thermometer of the pollution. Tests were carried out on 20 MT in a group of 73 subjects diagnosed with autism, the mean age of 8 years old. All 73 patients were over threshold for at least one metal. Seven metals (mercury, lead, antimony, tin, arsenic, thallium, cesium) had values over 50% (thirty-seven patients). The 26% (nineteen patients) exceeded the threshold for ten or more metals. Gadolinium 1521.21 exceeds threshold times. Mercury (x 379.95), tin (x 118), lead (x 108): presenting the coefficients more elevated. The average values exceed the threshold a lot: Mercury (x 28.14), Lead (x 10.56), Tin (x 9.98). With age increases the threshold exceeded for a lower number of metals. The analysis shows that gender has no significant difference, possibly results from the reduced number of females (18%). A future comparison research remains. We will explore the detoxification capacity difference between two genders affected by autism.
