Mitochondrial permeability and toxicity of diethylhexyl and monoethylhexyl phthalates on TK6 human lymphoblasts cells

► Study provides evidence on the capacity of phthalates to induce hallmark events in apoptosis. ► Experimental doses consistent with levels of DEHP and MEHP encountered in the environment. ► Longer experimental time of exposures resembling continues environmental exposure.
