In fact, in one study, a dose of mercury sufficient to kill 1 percent of
lab rats (lethal dose «LD01»), when combined with a dose of lead sufficient to kill 1 percent, killed 100 percent of the rats.13 A similar test involving mercury and aluminum in cultured neurons killed 60 percent of the cells when the two low - dose toxicants (LD01) were combined.14 Even antibiotics have been shown to enhance the uptake, retention and toxicity of mercury.14 Additionally, testosterone appears to aggravate mercury toxicity during
development, while estrogen protects against it.15 This may explain why more boys than girls are diagnosed with autism
spectrum disorders and attention deficit disorders.
