Abstract

This article focuses on assessing the toxicity of five metals—cadmium, copper, nickel, lead, and zinc—both individually and in mixtures, to the Antarctic endemic bdelloid rotifer Adineta editae, a key microinvertebrate in Antarctic terrestrial ecosystems. The study found zinc to be the most lethal metal to rotifer survival, while lead and copper were most toxic to rotifer behavior, measured by the sublethal endpoint of chemobiosis (contraction into a tun), a protective response to stress. Metal mixtures exhibited antagonistic toxicity, with less effect observed than predicted by additive models. These findings highlight A. editae as a sensitive species suitable for contaminant risk assessments in Antarctica and underscore the ecological risks posed by metal contamination in ice-free terrestrial habitats near research stations.
