Toxicity evaluations of nanoclays and thermally degraded byproducts through spectroscopical and microscopical approaches.

ABSTRACT:

Background

Montmorillonite is a type of nanoclay that originates from the clay fraction of the soil and is incorporated into polymers to form nanocomposites with enhanced mechanical strength, barrier, and flammability properties used for food packaging, automotive, and medical devices. However, with implementation in such consumer applications, the interaction of montmorillonite-based composites or derived byproducts with biological systems needs to be investigated.

Methods

Herein we examined the potential of Cloisite Na⁺ (pristine) and Cloisite 30B (organically modified montmorillonite nanoclay) and their thermally degraded byproducts' to induce toxicity in model human lung epithelial cells. The experimental set-up mimicked biological exposure in manufacturing an
