3. Research by the University of Hong Kong

We have provided our testing service to the University of Hong Kong in a research of autism and mercury exposure.  Results indicate that Hong Kong children’s exposure to mercury is higher than adults in European Countries or U.S.  Also, the level of mercury in hair is higher in autistic children than that of normal children.
