5. In terms of the relationship between the level of mercury and its impacts on children's cognitive development, the results show, (1) "For the overall test scores, test scores of children with hair mercury levels ⩾1.0 μg/g appeared to be lower than those of children with levels <1.0 μg/g", but few children had levels in this upper range and these differences did not reach statistical significance.” (2) For math reasoning and visual-motor composite scores, "the association was positive for hair mercury levels below 0.5 μg/g (the higher the mercury level the higher the scores) and negative for levels between 0.5 and 1.0 μg/g (the higher the mercury level the lower the scores)."
