Cytotoxicity assessments by the neutral red uptake assay in HEK-293 cells. The cells were exposed to herbicides with 2 h of UV-C (254 nm) and UV-A (365 nm) treatments at 4 °C. Values are the mean ± SEM of experiments. The relative cell viability for cells treated with chemicals at LD50 dosage was set up as 100 %.
