Fig. 3. Percentage of viable and late apoptotic/necrotic cells after exposure to 0–800 mg L^–1 terpinolene and 3 mM arsenic solutions. At least 200 cells were counted in each biological replica. A small number of early apoptotic cells were ignored. Values are presented as mean ± SEM. Calculations were made from at least five independent biological replicas (n = 5).
