Probit analyses were performed for all data using Minitab® 16 (2013, Minitab Inc., LEADTOOLS, LEAD Technologies, Inc.); LC50 (μg cm−2) (95% CI): 50% lethal concentration values together with their 95% confidence interval; Slope (s.e.): slope of the concentration curve and standard error; χ2: goodness of fit test as accuracy of data fitting to probit analysis. Values showed no significant heterogeneity at the level of P ⩾ 0.05); n.f., not found.
