Comparative and Combined In Vitro Vasotoxicity of Nanoparticles Containing Lead and Cadmium

Dose Response. 2021 Feb 11;19(1):1559325820982163. doi: 10.1177/1559325820982163. eCollection 2021 Jan-Mar.

Abstract

In vitro toxicological experiments were performed on an endothelial cell line exposed to different doses of spherical nanoparticles of cadmium and/or of lead sulfides with mean diameter 37 ± 5 nm and 24 ± 4 nm, respectively. Toxic effects were estimated by Luminescent Cell Viability Assay, endothelin-1 concentration and cell size determination. Some dose-response relationships were typically monotonic (well approximated with hyperbolic function) while others were bi- or even 3-phasic and could be described within the expanded hormesis paradigm. The combined toxicity type variated depending on the effect it was assessed by.
