Cytotoxicity in WJSCs following 48 h of exposure to various concentrations of chemicals—Left panel: micrographs (25×) of WJSCs 48 h after exposure to four chemicals representative of four hazard classes; the four concentrations are shown from highest (far right) to lowest (leftmost column). Figure inserts in top right corner of each micrograph denote the exact concentration (in ug/mL) of the chemical used. Right panel: respective survival curves (y = % viability, x = concentration in log ug/mL) for each chemical and their IC₅₀ values (ug/mL; top right corner of plots). Arrows on survival curves depict the four respective concentrations shown on the micrographs on the left. Diamonds depict all tested concentrations. IC₅₀ values correspond to the curve area between the two solid arrowheads and the culture status delineated by the micrographs marked by two solid arrows in the left panel.
