Artemia is being used as a rewarding tool in toxicology. Usually; the brine shrimp larvae are tested to determine the effect
of heavy metals on biological systems. The present study assessed the secondary effect of mercury at various concentrations
on the biometry of nauplii and meta-nauplii of Artemia sp. Generally, the total length and abdominal width were limited by
increasing the mercury concentrations (Fig 1. and Fig 2.). However, hormetic responses were also observed under certain
concentrations.
