The strength and selectivity of the phytotoxicity of 11 sulfosuccinic acid ester surfactants were determined on the leaves of Tradescantia bicolor, and the data were evaluated by multivariate mathematical-statistical methods. Spectral mapping technique combined with stepwise regression analysis indicated that
